Sample output
Subject: quick question about your migration
Hi Sarah,
Saw on your engineering blog that you migrated from Heroku → Render last quarter — and that the Postgres rebuild took 3 weekends.
We built a tool that mirrors the same kind of migration in roughly 2 hours, with rollback. Three teams that switched off Heroku last year saved 40+ engineering hours each.
Worth a 15-min look? Yes or no — I'll send a calendar link if yes.
— Mark founder @ shiplane.dev
P.S. Happy to skip the call entirely and just send the 90-second demo if you'd prefer.
Variation B (specific observation):
Subject: the OAuth issue from your blog
Hi Sarah, your post on the Heroku → Render migration mentioned the OAuth callback URLs broke for 11 minutes during cutover. We built tooling that prevents that exact scenario — keeps both stacks live until you flip the DNS.
Worth a 15-min look?
— Mark
Variation C (peer reference):
Subject: Vercel's eng lead said you'd care
Hi Sarah, James at Vercel mentioned you ran a Heroku migration in October. We built the cutover tooling his team now uses — saves 30+ engineering hours on the Postgres step.
Worth 15 minutes?

FAQ
The single most important thing in cold email: the first line. It must prove you did 30 seconds of research. AI cannot do that for you — replace {your_research_hook} with a real fact about them. The prompt targets ChatGPT (GPT-4) and lives in the Marketing & Sales category on mycopyprompt.
This prompt is written for ChatGPT (GPT-4). It's a text/chat prompt — paste it into ChatGPT (GPT-4) (or compatible LLMs like Claude or GPT-4) to get the expected output.
1. Click the Copy button on this page to copy the full prompt. 2. Open ChatGPT (GPT-4). 3. Paste the prompt into a new conversation. 4. Replace any {placeholders} with your specifics, then send. Most prompts produce the right output on the first try; complex ones may need 1-2 iterations.
Yes — every prompt on mycopyprompt is free forever. No paywall, no signup wall for browsing or copying. You can use it for personal or commercial work, just don't redistribute the entire mycopyprompt library.
Absolutely — most prompts are templates. Look for {placeholders} (curly braces) and swap them with your own values. You can also reword sections, add constraints, or chain it with other prompts.
See the "Sample output" panel above — that's a real example of what ChatGPT (GPT-4) returns when this prompt runs. Your output will vary in wording but should follow the same structure and depth.
