$3.99
Works in Claude + ChatGPT
01Outputs all 4 emails in one shot: opener, follow-up 1, follow-up 2, and a breakup that actually gets replies
02Every email comes with a subject line, {{personalization tokens}}, and a specific CTA — paste-ready for Apollo, Instantly, or HubSpot
03Drop in your existing draft and get an annotated teardown showing exactly why your reply rate is under 1% — and a fixed version
04Subject lines pulled from a swipe file of 30 proven formulas, matched to your opener angle (pattern-interrupt, outcome-first, mutual connection, etc.)
05Works even if you have zero customers — includes a beta/no-proof-yet angle that doesn't feel desperate
06Refuses to write a 10-email spray-and-pray sequence; pushes back with what actually books meetings at your stage
What it does
You know your product. You've done the customer interviews. You can explain the pain in your sleep. But the moment you open a blank sequence in HubSpot, you write something that sounds like a press release, a LinkedIn post from a vendor you'd ignore, or worse — 'Just following up on my last email!'
This skill takes your ICP description, your value prop, and whatever proof you have (even if it's just one beta customer in Texas), and produces a complete 4-step cold email sequence in about 90 seconds. Every step has a subject line, body copy written in a human register, the right personalization tokens for your targeting level, and a CTA matched to where your prospects are in the buying journey. It also ships with a 30-formula subject line swipe file (subject-line-formulas.md) so you can swap angles without starting over.
Already have a draft? Paste it in and the skill loads sequence-teardown-examples.md to run a before/after teardown — the same format a $500/hr sales consultant would use — then rewrites the sequence with the problems fixed. It won't write you a 10-email follow-up chain, because that's not what books meetings at pre-seed. It will tell you why, and give you the four emails that do.
Frequently asked
Does it just generate the emails or does it also write the subject lines and tell me where to put personalization?
All four emails come with subject lines, {{personalization tokens}} already placed in the copy (e.g., {{CompanyName}}, {{JobTitle}}, {{RecentFunding}}), and a specific CTA for each step. You paste into your sequencer and fill the tokens — nothing left to figure out.
I don't have any customers yet. Will it just tell me I need social proof I don't have?
No. There's a no-proof-yet angle baked in. Tell it you're in beta and it writes sequences that lead with the problem and the mechanism, not a case study. It'll flag where a proof point would strengthen the copy so you know what to add when you land that first win.
Can't I just ask Claude to write a cold email sequence without buying this?
You can. You'll get a generic, slightly-too-long sequence that sounds like it was written by someone who has read about cold email but never sent one. This skill is tuned specifically for founder-led B2B SaaS outbound — the tone, length, follow-up pacing, and CTA logic are calibrated to what actually gets replies at pre-seed, not what looks good in a blog post.
Does it work with Claude.ai, ChatGPT, or my existing AI setup?
This is a Claude skill — it runs inside Claude.ai on a Pro or Team plan. It won't work in ChatGPT or via raw API calls. If you're already on Claude.ai, you just add the skill and it's available immediately in any conversation.
Is this included in my Claude subscription or is it a separate purchase?
It's a separate purchase on top of your Claude.ai subscription. You need an active Claude Pro or Team plan to run it, but the skill itself is bought here and added to your account.
