Email Campaigns — Universal Email Marketing

Write high-converting email campaigns for any business — newsletters, re-engagement sequences, B2B cold outreach, promotional emails, and automated drip camp...

Security Scan

This is an instruction-only skill that provides email subject-line formulas, templates, and prompt scaffolds for writing campaigns; its requirements and instructions are proportionate and consistent with its stated purpose.

Purpose & Capability

The name/description (email campaigns, templates, subject lines, segmentation strategies) match the SKILL.md content. There are no unexpected environment variables, binaries, or install steps required.

Instruction Scope

SKILL.md contains only templates, example prompts, and content-generation guidance. It does not instruct the agent to read local files, access system paths, exfiltrate environment variables, call external endpoints, or perform actions outside writing email copy.

Install Mechanism

No install spec or code files are present — instruction-only — minimizing filesystem and code-execution risk.

Credentials

The skill requests no credentials, environment variables, or config paths; nothing disproportionate to a copywriting/template skill is required.

Persistence & Privilege

always is false and the skill does not request persistent/system-level privileges. It does not modify other skills or agent configurations.

Assessment

This skill is a set of templates/prompts for writing email copy and appears safe to install. Before using outputs in production: 1) review and edit generated copy for accuracy, tone, and legal compliance (CAN-SPAM, GDPR, etc.); 2) do not paste or request sensitive customer data or credentials into prompts; 3) ensure unsubscribe links and delivery best practices are handled by your mailing platform — this skill does not send emails itself; 4) be cautious if you combine this skill with other skills that have send-email or SMTP credentials — those could cause the generated content to be sent automatically. If you need the skill to actually send messages, prefer explicit, auditable integrations that require the appropriate service credentials.

Keep each under 50 characters for mobile. No clickbait — must match email content.

[CTA]
[Single, clear action: read full article / book a call / reply with X]

[Acknowledge the time apart]
[Remind them of the value they signed up for]
[Give them a reason to re-engage — exclusive content or offer]

[Respect their time — this is the last one if they don't engage]
[One final compelling reason to stay]
CTA: [Keep me subscribed / Remove me from the list]

3. B2B Cold Outreach

[BRIDGE — why you're reaching out and how it's relevant to them specifically]

[VALUE PROP — 1-2 sentences: what you do + the specific result for their type of business]

[SOCIAL PROOF — brief: "I've helped [type of company] achieve [result]"]

[SOFT CTA — make it easy to say yes]
Would it make sense to have a quick 15-minute call to see if there's a fit?

[PROBLEM — the specific challenge your offer solves]

[OFFER INTRODUCTION — present it as the natural solution]

[WHAT'S INCLUDED — bullet points, keep it brief]

[SOCIAL PROOF — testimonial or result]

[URGENCY/SCARCITY — deadline, limited spots, or bonus]
