Sequenzy Email Marketing

Agent guide for operating Sequenzy. Use when Codex needs to authenticate, inspect identity, manage subscribers, create or edit campaigns/sequences/templates, generate draft email content, send a transactional email, read delivery stats, or decide whether a requested Sequenzy workflow is currently supported. Prefer the CLI when it is implemented, and fall back to the dashboard or direct API use when the current CLI surface is only partial.

Overview

Use this skill when the task is to operate Sequenzy, not to change Sequenzy's source code. Prefer the sequenzy CLI for supported workflows, treat packages/mcp/src/tools/index.ts 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.

Ground Rules

1. Treat packages/cli/src/index.tsx as the source of truth for which commands are actually wired.
2. Treat packages/cli/src/commands/ and packages/cli/src/api.ts as the source of truth for CLI behavior, payload shape, and API routes.
3. Treat packages/mcp/src/tools/index.ts as the source of truth for MCP tool names, arguments, and preflight validation.
4. Do not promise support for commands or tools that only appear in docs or --help text without an attached implementation.
5. Prefer sequenzy login for interactive auth and SEQUENZY_API_KEY for automation.
6. Prefer inspection before mutation whenever the workflow allows it.

Supported Workflows

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 or creation with companies list|get|create
• stats overview or stats by campaign/sequence ID
• subscribers list, add, get, and remove
• lists list and create
• tags list
• segments list, create, and count, including --match any, nested filter roots, custom event 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
• 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
• sequences list, get, create, update, enable, disable, delete, and cancel-enrollments, 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)
• AI generation with generate email, generate sequence, and generate subjects
• 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, and guide
• API key creation with api-keys create
• send one transactional email by template or raw HTML

Unsupported Or Placeholder Workflows

Treat missing subcommands as unsupported even when the noun exists. For example: campaign immediate send, pause/cancel flows, list deletion, tag mutation, and bulk subscriber import are not available through the current CLI handlers.

Execution Pattern

1. Check auth first with sequenzy whoami or by verifying SEQUENZY_API_KEY is set.
2. Pick the narrowest command that matches the use case.
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.
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. 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 being a stubbed success path in the current backend, and conditional email content requiring block JSON rather than raw HTML.

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}

Useful settings tabs include domain, tracking, localization, integrations, events, tags, goals, sync-rules, api-keys, widgets, and team.
