About this prompt
This prompt generates 10 cold email subject lines for a specific job title, industry, and solution — two for each of five distinct approaches. It's for SDRs, BDRs, and AEs building outbound sequences. Use it when you're writing a new email and want to test multiple subject line angles before selecting one, or when a sequence has plateaued and you need fresh variants.Choosing a subject line by instinct produces low variation across sequences and gives you nothing to learn from. This prompt generates two subject lines each for: curiosity gap, personalization, benefit-first outcome, question, and pattern interrupt — all labeled by approach for easy comparison and A/B testing. Each line is constrained to under 45 characters for mobile display and is written to avoid spam trigger words. Fill in [JOB TITLE] with the specific persona, [INDUSTRY] with the vertical, [YOUR SOLUTION] with what you sell, and [BRIEFLY DESCRIBE THE EMAIL CONTENT] with the core message or offer — the content context is important because the benefit-first and curiosity gap approaches need to reflect what is actually in the email body to avoid a click-through disconnect. Use the pattern interrupt lines carefully: they work best in early sequences where you have no prior touchpoints and need to break inbox noise; in a later follow-up where the prospect has already engaged, a personalization or question line typically performs better.The prompt
