What is cold-email-sequence-generator?

A tool for writing personalized cold-email campaigns made of several messages sent over time. It supports different campaign lengths, follow-ups, subject-line variations, timing suggestions, social proof, and calls to action.

Use it to create sales sequences, lead-generation campaigns, event outreach, and re-engagement emails for different audiences.

It organizes repeated outreach so prospects receive a planned sequence instead of one isolated message. It also helps compare different subject lines and adjust follow-up timing.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00059	$0.05033
Opus 5	$0.00030	$0.02516
Sonnet 5	$0.00012	$0.01007
Haiku 4.5	$0.00006	$0.00503

Security

Grade A, and why

cold-email-sequence-generator 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 9d 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.
