Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

email-marketing scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Email Marketing

This skill handles end-to-end email marketing — from strategy and copywriting to campaign execution and performance analysis.

When to Use This Skill

  • Drafting newsletters or email campaigns

  • Writing subject lines and preview text
  • Segmenting email audiences
  • Analyzing email campaign performance (open rates, CTR, conversions)
  • Planning email marketing calendars
  • A/B testing email variations
  • Creating lead magnets and opt-in sequences
  • Writing transactional emails (order confirmations, receipts, shipping updates)

Capabilities

1. Campaign Strategy

Email Types You Can Create:

  • Newsletters (weekly/monthly updates, curated content)
  • Promotional emails (launches, sales, limited offers)
  • Drip sequences (automated series triggered by actions)
  • Welcome sequences (new subscriber onboarding)
  • Re-engagement campaigns (win-back inactive subscribers)
  • Event invitations and follow-ups
  • Educational series (courses, tips, how-tos)
  • Transactional emails (receipts, confirmations, shipping)

Strategy Framework:

  1. Define the goal (awareness, engagement, conversion, retention)
  2. Identify the audience segment
  3. Choose email type and frequency
  4. Write copy following proven frameworks
  5. Design layout structure
  6. Set up automation triggers
  7. Define success metrics

2. Copywriting Frameworks

Subject Line Formulas:

  • Curiosity gap: "The one thing most [audience] get wrong about [topic]"
  • Urgency: "[First name], this expires in 24 hours"
  • Benefit-led: "How to [achieve result] without [pain point]"
  • Social proof: "[Number] people already [action] — here's why"
  • Question: "Are you still [struggling with X]?"
  • Personalized: "[First name], I noticed you [action]..."

Email Body Frameworks:

  • PAS (Problem-Agitate-Solve): Identify pain → amplify it → present solution
  • AIDA (Attention-Interest-Desire-Action): Hook → engage → create want → CTA
  • BAB (Before-After-Bridge): Current state → desired state → how to get there
  • 4Ps (Promise-Picture-Proof-Push): Make promise → paint picture → show evidence → CTA
  • Story-Lesson-CTA: Share relatable story → extract insight → drive action

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
