sequenzy-email-marketing

Primary agent guide for operating Sequenzy as an email-marketing platform. Use when an AI agent needs to authenticate, inspect identity, manage subscribers, create or edit campaigns/sequences/templates, control the campaign lifecycle (cancel, pause, resume, delete, duplicate), run campaign A/B tests, mutate lists/tags/segments, enroll subscribers into sequences, invite team members, triage and reply to inbox conversations, manage outbound webhooks, generate draft email content, send transactional email, read delivery stats, or decide whether a requested Sequenzy email-marketing workflow is currently supported. Prefer this over the generic sequenzy skill when both seem relevant.

Overview

Use this as the default skill for Sequenzy email-marketing/product operations: subscribers, lists, tags, segments, campaigns, sequences, templates, AI email generation, transactional sends, delivery stats, dashboard URLs, CLI/MCP behavior, and currently-supported workflow checks. Prefer the sequenzy CLI for supported workflows, treat the MCP server's tool list as the MCP source of truth when the task goes through MCP tools, and explicitly call out when a requested workflow is not wired in the current implementation. If both sequenzy and sequenzy-email-marketing match, load this skill first.

Ground Rules

1. Treat sequenzy --help and sequenzy <command> --help from the installed CLI as the source of truth for which commands and flags are actually wired.
2. Treat the MCP server's tool list (tool names, descriptions and input schemas) as the source of truth for MCP tool names, arguments, and validation.
3. Treat the API reference as the source of truth for request and response shapes.
4. Do not promise support for commands or tools that appear only in docs. Confirm them in --help or the MCP tool list, and report runtime "not implemented" or "unsupported" errors as limitations.
5. Prefer sequenzy login for interactive auth and SEQUENZY_API_KEY for automation.
6. Prefer inspection before mutation whenever the workflow allows it.

Create a draft directly from a complete selected group with campaigns from-audience --selection-json or --selection-file (MCP create_campaign_for_audience). Preserve every filter and all selected IDs; membership is frozen, while send eligibility stays live. Review selectedCount and eligibleCount before editing and scheduling.

Supported Workflows

For MCP tool effect annotations and feedback attribution, read MCP effect disclosures.

Read references/use-cases.md before executing anything non-trivial. The currently implemented CLI flows are:

• login and logout
• local auth/session check with whoami
• account inspection with account
• company inspection, creation, or brand/sender-identity updates with companies list|get|create|update
• stats overview or stats by campaign, sequence, or transactional ID, with custom --start/--end ranges, --email-type and --mailbox-provider scoping, --include-bots, and campaign clickedLinks plus poll/NPS polls arrays (sequence stats carry the same summaries per email step in steps[].polls)
• raw delivery/engagement event listing with events --campaign|--sequence, and per-delivery inspection with email-sends list|get plus bounce-suppression cleanup with suppressions get|remove
• subscribers list, add, update, get, and remove, with list fetching every page by default and supporting tag, segment, and list filters; add and update set native profile names via --first-name / --last-name (MCP add_subscriber / update_subscriber: firstName / lastName), so never store names in custom attributes; both also handle native phone numbers and SMS consent; add covers explicit list IDs with subscribers:write, while imports into explicit lists and dedicated list membership operations require lists:write; omitting list IDs keeps the default-list behavior
• background filtered-audience tagging with subscribers operations start|list|get|cancel; inspect failure samples, reuse request keys after uncertain starts, and reconcile uncertain contact updates before retrying
• contacts under Sequenzy review are held: a campaign whose audience includes them returns waiting_approval for every account and size, sequence emails to them pause the enrollment, and emailType: "marketing" transactional sends to them stay pending with an errorMessage starting "Held for review"; report this to the user instead of retrying or re-importing, which does not release them
• bulk subscriber imports with subscribers import / import-status, subscriber notes, custom event triggering with subscribers event (live or --occurred-at backfill), and bulk tag operations with subscribers tags add|remove
• B2B accounts with accounts list|get|upsert|members|add-member|remove-member|event|events|delete|suggestions|accept-suggestions; suggestions groups contacts by shared work email domain (read-only) and accept-suggestions <domain...> creates only the domains the user confirms; organization (account) attributes reach members as organization.* segment fields, sequence conditions and merge tags (account.* still works), event-started sequences can enroll once per organization with matching field organization.externalId, and account events can deliver to owners, admins, all members, or record only (customer organizations, not sequenzy account); accounts delete (MCP delete_account) deletes one customer organization and never the user's Sequenzy account, workspace or login, so never use it when a user asks to delete their own account
• lists list, create, update, delete, add-subscribers, remove-subscribers, and import alias for bulk list population from emails, JSON, CSV, or newline files
• tags list, create, update, and delete, with bare sequenzy tags still listing tag definitions for backwards compatibility
• segments list, create, update, delete, and count, including --match any, nested filter roots, custom event filters, push device/activity filters, and saved-segment composition filters
• templates list, get, create, update, and delete, with list supporting label filters and create/update accepting labels, raw HTML, or Sequenzy block JSON
• campaigns list, get, create, update including label and reply-to updates, schedule, and test, with list supporting label filters, create accepting labels plus raw HTML, Sequenzy block JSON, or prompt-generated content, update accepting labels plus raw HTML or Sequenzy block JSON, and schedule returning a review preview link; create and schedule both accept the audience via --segment or --target-lists-json/--target-lists-file
• campaign lifecycle control with campaigns cancel (stops scheduled, paused, waiting-approval, or sending campaigns immediately, no confirmation prompt), campaigns unschedule (returns a scheduled campaign or recurring series to draft), campaigns pause and campaigns resume for an active send (resume supports --spread-over-hours), campaigns update/campaigns schedule --max-recipients <count> to send to only the first N matching subscribers (--clear-max-recipients removes the cap), campaigns create/campaigns update --attach <files...> to send files such as a PDF report with every email (--clear-attachments removes them), campaigns delete (blocked while sending, scheduled, or paused - cancel first), and campaigns duplicate with --mode campaign|ab_test|variant
• For capped A/B campaigns, use at least one recipient per variant plus one for the winner. Raise or explicitly clear a rejected limit before scheduling again.
• campaign audience inspection with campaigns audience, true-to-send HTML previews with campaigns render / templates render / sequences render (subscriber or ad-hoc personalization, locale, tracking, --out), pre-send checks with campaigns check / templates check / sequences check --node (live broken-link and image verification plus the editor's content rules; --fail-on error for scripts), recurring sends with campaigns schedule --repeat weekly|monthly, and post-send re-engagement with campaigns resend-to-non-openers Preserve hard excludedCampaignOpenerIds through manual adjustments and repeated resends; audiences use live membership. Recreate older drafts missing this metadata from the original campaign, then review before scheduling.
• ab-tests list, get, stats, restart, update-variant, create, add-variant, delete-variant, and delete; create/add-variant/delete-variant/delete work on campaign A/B tests in draft status, variant A is the protected control, and restart reruns a finished sequence A/B test. For a sequence A/B step, sequences get --json and MCP get_sequence expose each variant's full blocks when ab_tests:read is granted; edit them only through ab-tests update-variant / update_ab_test_variant
• campaign variations (the editor's Canvas tab) with campaigns variations list|get|generate|create|update|section-options|discard|restore|use and the matching MCP *_campaign_variation(s) tools: generate returns at once (poll or --wait), nothing changes the campaign until use (drafts only, previous content kept as a variation), and variations are not A/B tests
• sequence-wide AI edits (the sequence editor's Emails view) with sequences edit-emails <id> --prompt "..." [--emails ids] [--sections ids] [--dry-run] and MCP edit_sequence_emails: without --emails the prompt decides (every email unless it names some), a look change is identical across the emails it restyles, each email reports changed/unchanged/failed, and changed emails are saved unless it is a dry run; emails written in HTML are edited as HTML, and A/B test steps are skipped; to try a few designs of one email first, use sequences variations generate <id> --email <emailId> --prompt "..." --wait / generate_sequence_email_variations, then sequences variations use <id> <variationId> --email <emailId> [--all] [--dry-run] / use_sequence_email_variation (nothing changes until use)
• MCP template and campaign tools support labels on list/create/update; MCP update_campaign also supports replyTo and replyProfileId, and MCP schedule_campaign schedules draft or already scheduled campaigns
• MCP search_subscribers supports list filters through list, listId, or listName; MCP add_subscribers_to_list accepts up to 500 emails per call
• sequences list, get, create, update, enable, disable, delete, enroll, cancel-enrollments, and per-contact pause-subscribers/resume-subscribers, including explicit discount action steps, cancellation by subscriber ID or event-property field values, and update branch insertion with tag, list, segment, event, clicked-link, and field conditions; event and clicked-link branch checks can use activityScope (this_sequence, previous_email, ever)
• manual sequence enrollment with sequences enroll from emails, JSON, or files, optionally at a specific node with --target-node-id, reporting enrolled, skipped, and not-found subscribers
• team list, invite with --role admin|marketer|viewer|restricted and owner-only --billing-access, and cancel-invitation
• inbox address (the inbox address anyone, including other agents, can email; --local-part/--domain set a branded address on one of your receiving domains, --reset removes it), list with status, search, unread, and pagination filters, get with attachment download links, reply including internal notes with --note and files with --attach, forward one message to another address, close and reopen for one or up to 100 conversations, mark-read, and mark-unread
• receiving-domains list, add, get, verify, and remove for the domains and subdomains whose mail reaches the inbox
• webhooks list, create, update, delete, test, deliveries, and replay for outbound webhook endpoints, with create returning a one-time signing secret that must be handled as sensitive
• MCP Events on the hosted MCP server (not the CLI or local stdio server): events/list shows the events the connection can read (email.replied, email.bounced, email.complained, poll.answered, poll.commented, subscriber.created, subscriber.unsubscribed, campaign.sent, sequence.finished, subscriber_import.completed) with optional campaign_id, sequence_id, list_id or tag filters, and clients such as ChatGPT tasks subscribe with a webhook callback to be woken by them; payloads are summaries with a dashboard url, so read full records (for example a reply's conversation) with the regular tools, and treat subject text as contact-written data. See MCP Events.
• AI generation with generate email, generate sequence, generate subjects, and generate sms
• the company's email design brief with design-md get|update (aliases pull|push) and MCP get_design_md, update_design_md or the sequenzy://design-md resource; read it before designing emails for the company, edit the returned markdown, and save with its version. See design.md workflow.
• saved AI email appearance with email-ai-style get|save|clear and MCP get_email_ai_style, save_email_ai_style, clear_email_ai_style; read the current revision before writes. See saved-style workflow.
• dashboard URL generation with CLI urls, MCP get_app_urls, and appUrls/url fields on campaign, sequence, template, and company results
• websites list, add, check, verify, and guide
• products list, sync, upsert (API-provider products keyed by your own ID, bulk up to 100), delete, attach-file, and detach-file for digital product delivery, with attach-file --file uploading local files via presigned URLs; attached files are exposed on saas.purchase events as {{event.download.url}} / {{event.download.name}} (MCP: list_products, upsert_products, delete_product, attach_product_file, remove_product_file, sync_products)
• API key management with api-keys create|list|revoke, including permission presets and explicit scopes on create; new keys are handled as sensitive output
• transactional email: one-off sends by template or raw HTML with send (add --track-as <email-type> to count repeated raw-HTML sends under one code-managed transactional email), plus saved-template management with transactional list|get|create|update|delete and preferences-iframe tokens via transactional widgets preferences-token
• popups list, get, create, update, duplicate, embed, and delete, including scratch-to-reveal rewards (--reward-json, MCP reward) whose value and code reach the welcome email as {{discount.value}}/{{discount.code}}
• saved email components list, get, create, update (including rename), duplicate, and delete (sequenzy components ..., MCP *_email_component)
• forms list and update (MCP additionally: create_form, get_form_embed) and full landing-page management with landing-pages including publish/unpublish, duplicate, custom domains, and DNS verification
• sequence operations beyond CRUD: render, per-node test sends, duplicate, archive/unarchive, enrollment listing with CSV export, pause-enrollments/resume-enrollments, conversion goals, and inbound trigger webhook get|configure|rotate
• template AI/manual localization with templates localizations set|sync, and company-wide translation of sequence and transactional emails with templates localizations coverage|translate-missing
• integrations: catalog, connect (API-key/webhook-secret providers; OAuth providers connect in the dashboard), list, get, activity, sync, disconnect (Lemon Squeezy, including cleanup retry, and SparkLoop), enable-sync/disable-sync, Shopify pixel/enable-pixel, two-way Attio sync with attio/set-attio-lists, and guide
• Meta Ads audience syncs with audience-syncs list|ad-accounts|create|update|delete|sync
• warehouse sync in from Snowflake/BigQuery/Redshift/Postgres with warehouse connections list|get|create|update|delete|test|preview and warehouse syncs list|get|create|update|delete|run|runs (MCP: create_warehouse_connection, preview_warehouse_query, create_warehouse_sync, run_warehouse_sync, list_warehouse_sync_runs and related tools)
• warehouse data exports to S3/GCS buckets with data-exports list|get|create|update|delete|test|run|runs (MCP: list_data_exports, create_data_export, update_data_export, delete_data_export, test_data_export, run_data_export, list_data_export_runs)
• deliverability and sending config: sender-profiles list|update, tracking settings|update (open/click tracking, direct third-party unsubscribe links with --unsubscribes off, --store-content off to keep no email content, subjects or open/click IP addresses, strict bot filtering, attribution window, double opt-in, auto-UTM), and sequence/step-level sending windows
• Shopify automation settings with shopify settings get|update (browse abandonment, cart abandonment, price drop)
• SMS operations with sms settings, sms update (label, brand prefix, link shortening), sms send-test, SMS sequence steps, and generate sms
• push notifications with push settings, push web, push ios set / push android set, push devices, push send-test, push campaigns, and type: "push" sequence steps for web, iOS, and Android, each with per-language versions (localizations; translate with push campaigns translate or push translate)
• moving a push audience from OneSignal, Braze, Customer.io or a CSV with push imports preflight|start|get|list|resume|cancel (MCP get_push_import_preflight, create_push_import, add_push_import_rows, start_push_import, get_push_import, list_push_imports, cancel_push_import): show the preflight warnings before starting, because imported APNs/FCM tokens only work with the same bundle ID, Apple team and Firebase project; web push is never imported; opted-out devices stay unsubscribed; contacts are matched by external ID then email and created quietly for opted-in devices (push-only, with no email or phone, when the device has only an external ID). See push imports
• iOS Live Activities and Android Live Updates with push live-activities list|start|update|end (MCP list_live_activities, start_live_activity, update_live_activity, end_live_activity): start remotely on one contact's iPhones (iOS 17.2+, alert required, attributes must include every field of the app's struct) and Android devices whose app observes the same type (platforms counts each), then update or end every running copy by the same contact and your activityId (end needs the final content state); tokenCount: 0 means nothing was sent. For many people at once (a game for every fan), start --segment|--list|--tag (MCP segmentId, listId, tag; up to 100,000 devices, needs campaigns:send) with a shared activityId, then update|end --broadcast (MCP broadcast: true) reaches every signed-in device running it; never broadcast a per-person id like an order. Confirm with the user before starting one, since a repeated start shows a second activity, and before any audience start
• in-app messages and content cards with type: "in_app" sequence steps (modal, banner, fullscreen, card, or html: custom HTML/CSS/JS such as a Survicate survey or Braze custom HTML, shown sandboxed by the SDKs with a JS bridge, Braze Liquid converted) that the customer's app (or the Sequenzy SDKs) fetches and renders, plus in-app list, in-app event, in-app delete, in-app stats, in-app templates (ready-made step configs), in-app write (AI copy from a brief), and in-app html validate|set (check a custom HTML document, put it on a step); a button with action: "request_push_permission" (template push-primer) is a push primer that asks for notification permission, with results in in-app stats, the app opt-in rate in push settings, and the contact's pushPermission attribute for segments
• in-app campaigns with in-app campaigns create|update|send|unschedule|stop|duplicate|estimate|stats: one in-app message or card for a list, segment, tag or filter audience, optionally scheduled, with --priority and --ends-at; launching writes nothing per contact, and each contact in the audience gets it the next time their app fetches its feed while the campaign is live, including people who join the audience later
• mobile apps: the iOS, Android, React Native and Flutter SDKs identify contacts, track custom events, register push tokens and show in-app messages and cards with a publishable key restricted by web-tracking create|update --app-ids com.example.app (MCP allowedAppIds on create_web_tracking_key / update_web_tracking_key) plus an identity token the app's backend mints with POST /api/v1/web-tracking-identities (for email, or externalId for users without one, then identifyUser(externalId, ...) in the app); never put a secret key in an app. App events cannot use built-in names such as saas.purchase
• mobile app companies: set websiteType: mobile_app (companies update --category mobile_app, MCP update_company) to get push-first journeys from sequences templates / list_sequence_templates; create them with sequences create-from-template / create_sequence_from_template (RevenueCat, Superwall and Adapty events; has_push_device branch with email fallback; daytime waits in each contact's timezone)
• integration event-to-tag sync rules with sync-rules get|update
• personal notification preferences with account notifications get|set
• account health with account-health (report), account-health run, account-health settings (--enabled/--no-enabled for the fixed Monday 05:00 UTC check, --autonomy draft_fixes|report_only; findings ride in the Monday weekly report and each person opts out with notifications set --account-health off) and account-health insight <id> dismiss|snooze|resolve|reopen, account-health fix <insightId> to build the draft sequence a finding asks for, account-health feedback <insightId> useful|not_useful [--comment <text>|--clear-comment] to pass on whether a finding helped the user (it reaches the Sequenzy team only and changes nothing; send it only when the user says so) (MCP: get_account_health, update_account_health_settings, run_account_health_check, update_account_health_insight, create_account_health_fix, submit_account_health_feedback); checks need more than 1,000 active subscribers and an email sent in the last 14 days, drafted fixes are inactive sequences named for the business with titled email steps; the check writes no email, they are written when the draft is opened in the dashboard or account-health fix <insightId> is run for it, and nothing is sent or activated
• single-contact createdAt values at most one hour old remain eligible for signup notifications; older dates and bulk imports do not notify on creation, but double opt-in confirmation can still notify, and sequence enrollment defaults are unchanged
• product feedback with feedback, sending missing-capability reports, bug reports, and other product feedback straight to the Sequenzy team (MCP: submit_feedback; not on the OpenAI-reviewed route)

Company Tracking Domain

Tracked links use one company tracking domain, shared by every sending domain (for example links.example.com). The first sending domain creates it on its root and returns its CNAME as website.dnsRecords.trackingRecord; publish it with the other records. It is optional and never blocks verification or sending: until it verifies, or if it breaks or is removed, links use the shared Sequenzy domain. Read it with tracking domain or get_tracking_domain. Set or change it with tracking domain set <hostname> or set_tracking_domain (any subdomain works; confirm the hostname with the user first), check it with tracking domain verify or verify_tracking_domain, and remove it with tracking domain remove --yes or remove_tracking_domain only after the user confirms: links and images in emails already sent through it stop working. Changing it keeps those links working while the old CNAME stays. websites configure and configure_sending_domain are deprecated.

New sending domains publish their bounce subdomain as one CNAME (website.bounceRecords.cnameRecord, the Bounce: line in the CLI), which also works where the DNS host blocks custom MX records. Domains added earlier show SPF TXT and MX records instead (bounceRecords.style is mx_txt); keep those. Never publish both at the same name.

When dnsRecords.platformDnsRecords is present (domains added from October 2026), publish those CNAMEs instead of the DKIM TXT in byodkimRecord: the sq1 and spare sq2 DKIM selectors and an rp2 return-path CNAME (bounces on domains added October 14, 2026, srp on some domains added October 15, 2026). Publish all of them; only entries with required: true block verification, and that return-path CNAME, once it resolves, aligns SPF on every email.

Use sequenzy websites add <domain>, websites check <domain>, and websites verify <domain> for sending-domain setup and verification. MCP provides add_sending_domain, check_website (get_sending_domain on the OpenAI-reviewed route), and verify_sending_domain.

When website.dnsUpgrade.status is available (a verified domain on the previous record set, including an older SES-only domain that has a working DMARC record; without one the start returns 400 and the status is unavailable, so help the user add DMARC first), websites upgrade-dns <domain> or upgrade_sending_domain_dns moves it onto the current per-domain CNAMEs without removing it: a recommended, optional one-time upgrade to our new DNS structure for better deliverability and security. Confirm with the user first, since they must edit DNS. Relay dnsUpgrade.records (four CNAMEs) to add next to the current records, removing nothing; the domain keeps sending on its current records and switches by itself about an hour after the required ones are visible on public DNS (websites verify checks now but does not skip the wait). Sending is normally not interrupted at the switch; if that isn't possible for a domain, emails sent through Amazon SES can be held for a few minutes. The domain also gets a new 2048-bit DKIM key; the four CNAMEs stay the same. When status is completed, tell them they may delete oldRecords (optional; each is marked removed once gone from public DNS; replacedRecords lists them before the switch) after deleteOldRecordsAfter (8 days after the switch; for an older SES-only domain that includes the old return path MX and TXT at send.<domain> and the DKIM TXT, and DMARC stays). Once started, an upgrade can't be cancelled; until the switch it changes nothing.

Receiving Domains

A receiving domain is a domain or subdomain whose mail reaches the Sequenzy inbox: mail to any address on it arrives. A workspace has one, and like the tracking domain it serves every sending domain: once it is verified, replies to emails from all sending domains come back to reply addresses on it. Until then, replies use Sequenzy's shared address. Workspaces that set up several before keep them; replies then prefer the sender's own domain or one on the same root, else the oldest verified one. Adding a second one returns 409 limit_reached. Manage it with sequenzy receiving-domains (list, add <domain>, get <domain>, verify <domain>, remove <domain> --yes) or MCP list_receiving_domains, add_receiving_domain, get_receiving_domain, verify_receiving_domain and remove_receiving_domain. After adding one, publish its MX record (and the TXT record when listed), then verify; the first verification turns Inbox on. verified means mail arrives and new reply addresses use it; pending means the records are not found yet (a new name is reserved for 7 days); failed means something broke: mail that still arrives is accepted, but new reply addresses use Sequenzy's address until it is fixed. A domain that already receives email elsewhere (its MX points at Google Workspace, Microsoft 365, Cloudflare Email Routing...) is refused with 409 domain_has_mailbox: suggest a subdomain such as support.acme.com and confirm the name with the user. 503 dns_check_failed means the MX lookup got no answer; retry in a minute. Turning Inbox on with replyTrackingEnabled (companies update --enable-reply-tracking, MCP update_company) returns 409 receiving_domain_required when the workspace has no verified receiving domain and has never received a conversation; add a receiving domain instead. Remove one only after the user confirms: all mail to it stops, including replies to emails already sent, and a branded inbox address on it is cleared. Sending domains (websites, add_sending_domain) no longer set up receiving; inbound* fields that may still appear in website.dnsRecords describe an older reply setup.

Unsupported Or Placeholder Workflows

Treat missing subcommands as unsupported even when the noun exists. The main remaining gaps: campaign immediate send (no "send now" command - schedule with a near-future --at timestamp instead), form creation and embed snippets (MCP create_form / get_form_embed only), and image asset upload (MCP upload_image_asset only, PNG/JPEG/GIF/WebP up to 10MB). Cropping an already hosted image is supported: sequenzy images crop <url> --aspect 16:9 (MCP crop_image_asset). Bulk list population is supported through sequenzy lists add-subscribers and its sequenzy lists import alias, not through subscribers add. Send feedback only when the user explicitly asks you to send it. Before submitting, tell the user that the message goes to the Sequenzy team. Follow the active MCP tool's data restrictions; omit credentials, unrelated subscriber data, email content, and raw API/debug payloads.

Workspace Roles

Inspect sequenzy account or MCP get_account before choosing a privileged workflow. Account-key permissions combine selected scopes with your current workspace role; roleRestrictedScopes identifies scopes blocked by that role. canSendLive means at least one delivery workflow is available, not that every send tool is allowed.

Marketers can manage marketing content, subscribers, campaigns and sequences, including marketing test sends and unscheduling. They cannot use transactional sending or manage team, billing, integrations, API keys, sending identities or workspace settings. Choose existing sender/reply profiles; inline creation of a new profile is also restricted. Transactional-backed templates and their campaign, A/B and sequence sources stay protected through copies, previews, share links, analytics and retained send history. Use the narrowest eligible role; billing access cannot be granted to marketers or restricted members.

Execution Pattern

1. Check auth first with sequenzy whoami or by verifying SEQUENZY_API_KEY is set. If MCP tools return MCP_AUTH_REQUIRED, the server has no key: relay the signup link and setup steps from howToFix to the user instead of retrying.
2. Pick the narrowest command that matches the use case. With an account key (seq_user_) that reaches more than one company, pass --company (MCP: select_company or companyId). Without it the API runs in a default company; the CLI prints a Note: line on stderr naming it, MCP appends a note to the tool result, and REST responses carry X-Sequenzy-Company-Id plus X-Sequenzy-Company-Defaulted: true. After a subscriber write, check sequenceTriggersRan: false with sequenceTriggersSkippedReason: "missing_scope" means the key lacks automations:trigger, so the write was saved but no sequence started. Tell the user instead of reporting that the sequence started.
3. Validate IDs, recipient email, subject, template, or content input before issuing a mutation.
4. Surface CLI limitations directly instead of inventing a workaround.
5. If the workflow is unsupported in the CLI, say whether the next-best path is the Sequenzy dashboard or direct API use. Submit feedback only if the user explicitly requests it, after explaining that it goes to the Sequenzy team.
6. When you create, inspect, or schedule a campaign, sequence, template, or company and the user may want to review/edit it, surface the dashboard URL from url, previewUrl, or appUrls in the tool/CLI output. If needed, generate it with sequenzy urls or MCP get_app_urls.
7. Destructive commands (delete, delete-variant, cancel-invitation, and similar) prompt for confirmation. Pass --yes (or -y) to skip the prompt; --yes is required when stdin is not a TTY, which covers most agent and CI runs.
8. Treat API keys, webhook signing secrets, and other one-time credentials as sensitive output. Do not paste raw secret values into chat, logs, tickets, or public transcripts. Capture them to a user-approved secure destination such as a password manager, secret store, encrypted file, or local .env file outside version control; otherwise redact the value and report only where it was saved plus a short fingerprint.
9. Call out implementation caveats that matter operationally, such as whoami using cached local auth state, sequence creation supporting both --goal and explicit step modes, explicit discount steps requiring Stripe before activation, generated sequences being capped at 10 emails, campaigns test queuing a real email rather than confirming delivery, and conditional email content requiring block JSON rather than raw HTML.

campaigns test requires a verified sending domain and returns emailSendId and jobId. Inspect delivery with sequenzy email-sends get EMAIL_SEND_ID. Use websites check to read stored status and websites verify to run a fresh DNS check; DNS verification and readiness to send are separate outcomes.

Dashboard URLs

Use SEQUENZY_APP_URL as the dashboard base when it is set; otherwise default to https://sequenzy.com.

Prefer actual URLs returned by the CLI/MCP result:

• sequence editor: /dashboard/company/{companyId}/sequences/{sequenceId}
• campaign editor: /dashboard/company/{companyId}/campaign/{campaignId}
• campaign preview/review: /dashboard/company/{companyId}/campaign/{campaignId}?step=review
• template/email editor: /dashboard/company/{companyId}/emails/{emailId}
• settings: /dashboard/company/{companyId}/settings
• settings tab: /dashboard/company/{companyId}/settings?tab={tab}

campaigns goals / list_campaign_goals also show company-wide Settings goals in companyGoals. These already apply after an open or click within their window; do not recreate them as campaign goals merely to make them apply. Inactive goals remain listed. Manage company-wide definitions in Settings.

Useful settings tabs include domain, tracking, localization, integrations, events (includes sync rules), tags (includes labels), goals, api-keys (includes SMTP), widgets, and team. Older sync-rules, labels and smtp tab links still open the tab that contains them.

References

• references/command-reference.md: exact command shapes, env vars, behavior, and caveats.
• references/use-cases.md: decision trees and examples for the most common agent tasks.

For default footer changes, preserve the requested scope and use the preview/token workflow in the command reference. Render before/after HTML when a visual check would help.

For event-driven sequence testing, use the live sequence test workflow in references/command-reference.md. Supply cart IDs and arrays as event properties, inspect the returned run before retrying, and account for real action side effects.

Reuse received event data for sequence tests

Use sequenzy events sample <eventName> --company <companyId> --json, MCP get_event_sample, or GET /api/v1/events/sample?eventName=<eventName> to read the latest retained payload in your workspace. Requires subscribers:read. This includes older and custom events across all subscribers; sample: null means none exists. Copy sample.properties into the test run's customVariables (CLI --event-properties) and edit as needed. The dashboard's Use latest received event button replaces the JSON field. Copying data does not change the selected recipient or fire an event. Clear the field, omit the properties, or pass {} to test without overrides. Lookup errors are safe to retry; starting a real test still has delivery side effects.

When renaming a company, offer optional exact-match footer replacement with update_company (name, renameMatchingFooters: true, previousCompanyName from get_company). Preserve custom names and protected campaigns. Omit the flag unless requested; refresh and reconfirm on 409. See the command reference for CLI usage.

For footer typography, patch emailTheme.typography (footerFontFamily, footerFontSize 10-16px, footerLineHeight 1-2; null resets each) with update_company: it styles footer blocks and the auto-added footer, and a footer block's own fontFamily still wins. Change the auto-added footer's colors and copy with update_company footerTheme, a merge patch where null resets a field; do not replace brandColors for this. Edit the double opt-in confirmation email (consent.doubleOptInEmailId from get_tracking_settings) with update_template, keeping {{DOUBLE_OPT_IN_URL}} in the content: an edit without it returns 400.

For cart design, use preview_cart_items or sequenzy blocks preview-cart to inspect supplied items, suggest fields and preview edge cases. Confirm numeric price units explicitly; apply selected mappings and preset settings through existing block update tools. Scenario previews never save. See the command reference for inputs and reset behavior.

Automation input and errors

Use send --json --company COMPANY_ID for scripted sends and provide one stable --idempotency-key per logical email. Keep the accepted receipt and inspect its emailSendId; queued does not mean delivered. Supported text-file inputs accept - for stdin, with one logical stdin input per invocation; binary uploads still require paths. Parse CLI stderr as JSON Lines, preserving warning/recovery records and their request keys before terminal error envelopes. Inspect stdout on nonzero exits too: partial event imports retain their counts and row failures there without a terminal stderr error. MCP failures include the error envelope in structuredContent while retaining isError and text. Honor advisory retryAfterSeconds, but inspect status and reuse the original key and input before repeating a write. Both clients retry a read (GET) up to 3 times within about 3 seconds after a 502, 503, 504 or network error; writes are never retried automatically.

For sequence review, keep the same sample contact across email steps and A/B variants. Use simulation to check readiness and the existing activation and enrollment commands when requested. See use cases.

Campaign A/B progress, live audience/time changes, early finish and recovery are described in the command reference.

Transactional labels

Organize transactional templates with company labels using transactional create/update --label Billing Receipts, transactional list --label Billing, and transactional update receipt --clear-labels. MCP create/update/list tools accept labels; [] clears assignments, while omission preserves them on update. Get/list responses include label names. Labels only organize templates; they do not send email. See the command reference for validation and retry behavior.

Private lists support allowMemberUnsubscribe in API/MCP and --allow-member-unsubscribe / --no-allow-member-unsubscribe for CLI list create/update. Default off; omission preserves on update, false clears, null is invalid. When enabled, current members see the name and may opt out; they cannot join or rejoin through preferences. Public lists ignore this stored setting.

Interactive MCP previews

Use render_email to show a saved campaign, template or sequence email in desktop/mobile preview in MCP Apps clients. Before scheduling a campaign or activating a sequence, run check_email (CLI: campaigns check, sequences check --node, templates check) and fix error issues, especially links.broken; restricted links refused an automated check and only need a manual look. Use preview_sequence with explicit company and sequence IDs for a connected flow; click steps to render their saved emails and available A/B variants. Previews are read-only and never authorize sends, activation or enrollment. Respect personalization warnings and unavailable variant content. See the command reference for host restrictions and text-only fallbacks.

Keep email and sequence previews primary. For supporting workflows, use open_image_upload for an explicit user-submitted image and monitor_subscriber_import for an existing import. Pin companyId; check the image library before retrying uncertain uploads.

open_sequenzy (all inputs optional) opens a workspace view listing a company's sequences and campaigns; Claude also lists it on its Artifacts page so users can open it without a prompt. Views can expand into Claude's side panel or full screen. While a preview is open it offers view tools: call get_view_state before acting on "this email", open_sequence_step / open_sequence / open_campaign_email / show_sequence_overview / set_preview_width to change what it shows, and reload_view after you edit the content on screen so the user sees the change. View tools only change the display; edits still go through the normal write tools.

Capture submission history

Use sequenzy submissions <type> <id> --json or MCP list_capture_submissions to inspect immutable accepted payloads and labels. Requires subscribers:read plus widgets:read for forms/popups or landing_pages:read for landing pages. Filter using --field session --value morning (MCP field and value); both are required together. Follow nextCursor with unchanged filters. CLI --csv exports all matching pages; MCP format: "csv" adds a CSV string for one page. Tracking covers forms, popups and landing pages. Reconstructed history is explicitly marked with payload.recovery; treat its date as an evidence event time, not a verified submission time. Records contain normalized accepted answers, not raw headers/tokens or current profile values, and are not proof of double opt-in. Contact/form/company deletion removes snapshots. Never invent historical answers or automatically resubmit a form to recover a missing record: retries can repeat subscriber side effects.

The submission-payload tool is available on standard MCP. The OpenAI-reviewed MCP profile excludes it under its existing raw-payload restrictions; use the dashboard, API or CLI for this workflow on that profile.

For reconstructed submissions, preserve payload.recovery provenance and describe source attribution as inferred. CLI human output labels event time. CSV exports containing recovered rows append record_origin, timestamp_meaning and recovered_at. Do not fabricate missing answers or perform an operator recovery through subscriber writes.
