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-sequences 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 5d 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 Sequences

Plan and write email campaigns. Sequences (multi-message flows triggered by events) and broadcasts (one-off sends). Stack-agnostic. Works with any email service provider.


When to use

  • Writing welcome and onboarding email sequences
  • Planning lifecycle campaigns (activation, retention, win-back)
  • Writing transactional emails (receipts, password resets, notifications)
  • Newsletter design and writing
  • Abandoned-cart or re-engagement flows
  • Writing a one-off broadcast, launch announcement, or news email
  • Drafting email subject lines and preview text for any send

When NOT to use

  • Landing pages and conversion pages (use landing-page-copy)
  • Long-form articles (use content-and-copy)
  • Brand voice work (use brand-voice)
  • Analytics setup for email (use analytics-strategy)

Required inputs

  • The audience (segment or list)
  • The trigger or context (signup, purchase, abandonment, time-based, manual)
  • The goal of the email or sequence
  • Brand voice
  • Any technical constraints (provider, deliverability requirements)

If the audience is undefined, define it before writing. Generic emails to "everyone" perform worse than targeted ones.


The framework: 6 sequence types

Most email programs run a handful of standard sequence patterns. Each has its own goals, structure, and pitfalls.

1. Welcome / onboarding

Triggered by signup. Goal: get the user to first value.

Typical structure (5 emails over 14 days):

  • Email 1 (immediate): Welcome. Confirm they're in. State what happens next. Single CTA: the next obvious action.
  • Email 2 (day 1 or 2): First-value step. Help them get to a quick win or core action.
  • Email 3 (day 4 or 5): Education. Show them something they probably haven't discovered yet.
  • Email 4 (day 8): Social proof. Customer story or use case relevant to their segment.
  • Email 5 (day 14): Outcome reminder. Where they could be in 30/60/90 days. Soft commercial cue.

Common failure: Front-loading product features. Users don't care about features yet; they care about getting to value.

Changes

What this file has done since we first saw it

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.
