AI email fix-prompt generator
AI is great at rewriting email, if you tell it what's actually wrong. Paste your HTML to get a grounded prompt for Claude or ChatGPT that spells out every CSS compatibility issue and its fix, so the model gets it right the first time.
Frequently asked questions
What does this generate?
A structured markdown prompt containing your original email, a per-client compatibility summary, and every CSS issue with its recommended fix. You paste it into an AI assistant and it has everything it needs to rewrite the email correctly, instead of guessing about email-client quirks it doesn't know.
Why not just ask the AI to 'fix my email'?
General models don't reliably know that Outlook ignores flexbox, or that Gmail strips <style> blocks. A vague request produces plausible-but-wrong edits. This prompt grounds the model in the specific, verified issues in your email and the exact fixes, so the output is accurate.
Which AI assistants does it work with?
Any of them: Claude, ChatGPT, Gemini, or the AI built into your editor. It's plain markdown, so paste it wherever you work. The more capable the model, the better the rewrite.
Do you send my email to an AI?
No. This tool only analyzes your HTML and builds the prompt text. You choose if and where to paste it. Nothing is sent to any AI provider by us, and your HTML is not stored after the response.
