Cold Email Sequence Architect
Designs a multi-touch cold email sequence with the breakdown that actually gets opens, replies, and meetings.
What it does
Builds a 3-7 email sequence targeting a specific ICP. Each email has a clear job (open / engage / pattern-interrupt / hand-off). Avoids the spam-filter triggers, the over-templated voice, and the "send 10 followups they all get ignored" pattern.
When to use
- ✓New outbound campaign for a specific ICP segment
- ✓Existing sequence has 0.5% reply rate and you want to redesign
- ✓Pitching a new product where existing playbook doesn't fit
When not to use
- ✗You haven't validated the ICP yet — get one good conversation first via warm intro
- ✗You're spamming a list of 50,000 — that's not cold email, that's spam

# Cold Email Sequence Architect
A good cold sequence makes one well-targeted person reply. A bad one annoys 1,000 people into spam-marking you. The difference is design, not volume.
## Required inputs
1. **ICP** — title, company size, industry, pain you're solving for
2. **Offer** — what you'd actually deliver
3. **Differentiation** — why this prospect would care about your version vs. alternatives
4. **Sequence length + cadence** — number of touches, days between
5. **CTA per email** — what action do you want from the recipient
## Output
### Email 1 — intro (sent day 1)
- Subject line: 4-7 words, specific to prospect's world, no urgency theater
- Opening: name the specific reason you reached out (named role at named company)
- Value statement: 1 sentence on what you'd offer
- CTA: low-friction (15-min call, async question, link to short asset)
### Email 2 — proof / specific (day 3-4)
- Reference a specific public signal about the prospect's company (recent hire, launch, news)
- Show 1 proof point relevant to them (case study, metric, named customer)
- Same low-friction CTA
### Email 3 — pattern interrupt (day 7-8)
- Short. 2-3 sentences max.
- Different angle than emails 1-2 (if they were rational, try emotional; if they were features, try social)
- Optional: a soft "should I close the loop on this" framing
### Email 4 — handoff (day 14)
- Honest "I'll stop following up but here's how to find me"
- One useful artifact (link to relevant guide, calendar link)
- Closes the loop
## Anti-patterns
- "Hope this finds you well"
- "Quick question" subject (lying — it's never quick)
- "Following up" or "Bumping this" as a touch (no new value, just guilt)
- Emoji in subject from a corporate email
- Mass-personalized "I saw you went to [school]" (creepy at scale)
## Voice rules
- Read each email out loud — if it sounds like a sales template, it is
- Variable insertion that breaks on edge cases (name fallback, company variants)
- One sentence per paragraph, white space matters in cold
## Validation
- A/B test subject lines, not body copy
- Track reply rate by touch # — if all touches have similar reply rate, the sequence isn't working
- Track unsubscribe / spam-flag rate — if > 1%, the targeting is wrong
Example prompts
Once installed, try these prompts in Claude:
- Build a cold sequence for VP Engineering at Series B SaaS (50-300 employees). Offer: our agent-eval platform. 4 emails over 14 days.
- My current 7-email sequence has 1.2% reply. Help me redesign — keep the offer the same but rebuild the structure. [paste current sequence]
