Cold Email Copy That Gets Opened

What it does

Writes four-email cold sequences prioritizing subject line and first line to maximize opens, includes a personality fallback when there's no personalized hook, uses spintax variations, and respects deliverability constraints. Runs a mechanical AI-tell lint (like em dashes) before delivering the final draft.

When to use it

• When you need a new cold email sequence for an offer or niche.
• When your current emails sound generic or AI-written.
• When you use Email Bison or Instantly and need copy compatible with those platforms.

Steps

1. Share the offer, the ICP, and any angle you've already tested.
2. The assistant writes the four-email sequence with an opens-first focus.
3. It applies the personality fallback when no personalized hook is available.
4. It generates spintax variations for A/B within deliverability limits.
5. It runs the AI-tell lint and fixes whatever it finds.
6. It delivers the sequence as a draft for your review before loading it to the platform.

# Cold Email Copy That Gets Opened

## 1. What it does

- Writes four-email cold sequences prioritizing subject line and first line to maximize opens, includes a personality fallback when there's no personalized hook, uses spintax variations, and respects deliverability constraints. Runs a mechanical AI-tell lint (like em dashes) before delivering the final draft.

## 2. When to use it

- When you need a new cold email sequence for an offer or niche.
- When your current emails sound generic or AI-written.
- When you use Email Bison or Instantly and need copy compatible with those platforms.

## 3. Step by step

- Share the offer, the ICP, and any angle you've already tested.
- The assistant writes the four-email sequence with an opens-first focus.
- It applies the personality fallback when no personalized hook is available.
- It generates spintax variations for A/B within deliverability limits.
- It runs the AI-tell lint and fixes whatever it finds.
- It delivers the sequence as a draft for your review before loading it to the platform.

## 4. Safety rules

- Safety rules: everything ships as a draft first; nothing is sent, published, or paid for without your explicit approval; no data, numbers, or results are ever invented; no credentials or secrets are typed into chat.

## 5. Best practices

- Always review the full draft before approving any send, publish, or payment.
- If real information (data, numbers, results) is missing, ask for it to be flagged as pending instead of invented.
- Keep credentials and keys out of chat; set them in environment variables or your secrets manager.

## 6. GoHighLevel integration

- Where relevant, results can be saved as contacts, tags, tasks, or notes inside your GoHighLevel sub-account.
- No automation inside GHL (workflow, campaign, trigger) activates without your review first.
