Write Email Subject Line Variations
Write subject lines and preview text in different styles, so an A/B test compares approaches rather than synonyms.
The Prompt
Write 10 subject lines for a [campaign] email to [audience]. Use five styles, two lines each: direct, curiosity, benefit, urgency, and personal. Keep each under [character limit] characters and pair each with preview text that adds new information rather than repeating the subject. Avoid spam-trigger formatting such as all caps and repeated exclamation marks. Recommend two to A/B test first.
How to use this effectively
- Set a real character limit matching your email platform's preview cutoff.
- Ask for genuinely different styles, not synonyms, so the test tells you how your audience wants to be spoken to.
- Write preview text that adds new information — repeating the subject line wastes the second line.
