Testing
Two versions to A/B test
Write a second version of a cold email that tests one clear difference against the first.
The prompt
Here is our current cold email:
{{email}}
Write a version B that changes only ONE thing, so an A/B test tells us something. The thing to test: {{what_to_test}} (for example: the opening line, the proof, the question at the end, the length).
Return:
1. Version B.
2. One sentence on what's different and what we'd learn if it wins.
Keep everything else identical, including {{tags}}.Example of what it writes
1. (same email, new closing question) ...Who handles new business at {{companyName}}?
2. Tests a 'who's the right person' ask against an interest question; if it wins, our list reaches the wrong people too often.How to use this prompt
- Copy it into any AI tool, such as ChatGPT or Claude.
- Replace each {{field}} with real details about you and the person you're writing to. The more specific they are, the less generic the result.
- Check every fact, name and number in what comes back: AI can sound sure about things that aren't true.
- Cut it down if it runs long. A cold email reads best under about 75 words.
- Send it to yourself and read it on your phone before anyone else sees it.
