Cold Email Sequence

When NOT to use

• Warm leads who already know the sender — use a direct one-off email instead
• Lifecycle, onboarding, or nurture flows for existing users — use marketing-skills:email-sequences
• Transactional emails (receipts, password resets, notifications)
• Post-call follow-ups — use sales-skills:follow-up-emails
• Long-form newsletters or content emails — use marketing-skills:newsletter

Prerequisites

• Context on the target audience
• The product/offer being pitched
• Social proof or case studies (with real numbers)
• The source/trigger connecting the sender to these leads

The Framework: James Shields Cold Email Rules

Rule 1: Personalize the Subject, Not the Body

• Subject references the trigger (post, event, comment)
• Body uses {{firstName}} only

Rule 2: Three Sentences + PS

• S1: Context/trigger (why you are emailing)
• S2: What you built / the offer
• S3: Social proof (specific numbers)
• PS: Soft opt-out

Rule 3: Irresistible Offer

• Free access, no strings
• "I just want honest feedback"
• No demo, no call, no commitment

Rule 4: Low-Friction CTA

• Reply with one word: "I'm in"
• NOT "book a call" or "schedule a demo"

Rule 5: No Fluff

• No em dashes (use periods)
• No "I hope this finds you well"
• No bullet points or formatting in the email output (this rule applies to what you send to prospects, not to this skill doc)
• Write like texting a colleague

The Workflow

Step 1: Gather Inputs

1. Trigger/source: What connects the sender to these leads?
2. Product: One-line description
3. Social proof: Case study with numbers
4. Offer: The free/low-friction offer
5. CTA: Reply word (default: "I'm in")
6. Sender: First name only
7. Existing draft: Any copy to work from?

Step 2: Email 1 — The Opener (Day 0)

Subject: [personalized to trigger, lowercase, casual]

Hey {{firstName}},

[1 sentence: I saw your {trigger}. Brief validation.]

[1-2 sentences: What I built. Concrete.]

[1-2 sentences: Social proof. Specific numbers.]

[1 sentence: The offer. Free, no strings.]

[CTA: Reply "I'm in" and I'll {action}.]

[Name]

PS [Soft opt-out]

Present to user. Refine until approved. Do NOT proceed until locked.

Step 3: Email 2 — The Follow-Up (Day 3)

Subject: (same thread — blank)

Hey {{firstName}},

[1 sentence: Follow up. Acknowledge inbox noise.]

[2 sentences: NEW social proof. Different client, different numbers.]

[1 sentence: Restate offer.]

[Same CTA.]

[Name]

• Shorter than Email 1 (no PS)
• NEW social proof (never repeat)
• Same CTA

Present to user. Refine until approved.

Step 4: Email 3 — The Breakup (Day 7)

Subject: (same thread)

Hey {{firstName}},

Last one from me on this.

[1 sentence: Tool is live. Others using it.]

[1 sentence: Final CTA.]

[1 sentence: I won't email again.]

[Name]

• 4 sentences MAX
• "I won't email again" creates urgency
• No new pitch

Present to user. Refine until approved.

Step 5: Save Complete Sequence

Save to the current working directory as {campaign-name}-sequence.md with all 3 emails, timing, contact list info, and send-from address.

Quick Reference

Formatting rules (output emails): no em dashes, no exclamation points in body, no bold/italic/bullets, lowercase subject, short paragraphs (1-2 sentences), {{firstName}} for personalization, first-name-only signature.

Output file: {campaign-name}-sequence.md — ready to load into your sending platform (Instantly, Smartlead, Lemlist, Apollo, etc.).

Common Mistakes

Examples

These are fully written sample emails for a fictional company called Acme Analytics selling a free Slack analytics teardown. Replace {firstName}, the trigger, and the proof with the real campaign data.

Example Email 1 — Opener (Day 0)

Subject: your post on slack sprawl

Hey {{firstName}},

Saw your post about every team spinning up its own Slack channel and nobody knowing where decisions live. Same pattern at every 200+ person company we look at.

I built a free teardown at Acme Analytics that maps your top 50 channels, flags the dead ones, and shows where decisions are actually getting made. Takes about 10 minutes to run.

We did this for the ops team at Northwind last month and they killed 38% of their channels in a week.

No call, no demo, no pitch. I just want to see if it holds up on a bigger Slack workspace.

Reply "I'm in" and I'll send the teardown link.

Felipe

PS If this is not your problem right now, just reply "not now" and I'll go away.

Example Email 2 — Follow-Up (Day 3)

Subject: (blank — same thread)

Hey {{firstName}},

Following up once in case my last note got buried.

Ran the same teardown for a 400-person fintech yesterday. They found 12 abandoned project channels and one private channel where their old CTO was still pinned as admin.

Still free, still no call.

Reply "I'm in" and I'll send the link.

Felipe

Example Email 3 — Breakup (Day 7)

Subject: (blank — same thread)

Hey {{firstName}},

Last one from me on this.

The teardown is live and four ops leads ran it this week.

If you want yours, reply "I'm in" today.

I won't email again after this.
