Generate 5 Cold Email Subject Lines by Strategy

Produce five distinct subject lines — curiosity, urgency, personalization, benefit, pattern interrupt — for any cold

About this prompt

This prompt generates five cold email subject lines, each using a different proven opening strategy, for SDRs and BDRs writing first-touch outreach. Each line stays under 50 characters and avoids spam triggers. Use it when you're about to deploy a new cold sequence and want to A/B test approaches before committing to one.Weak subject lines kill cold email programs before a single word of body copy gets read. This prompt gives SDRs and BDRs five ready-to-test options — curiosity, urgency, personalization, benefit-driven, and pattern interrupt — so you can split-test across your sequence rather than guessing which angle lands. Fill in [TOPIC/PRODUCT FEATURE] with the specific capability or pain point you're leading with, [JOB TITLE] with the exact persona you're targeting, and [INDUSTRY] and [COMPANY/NAME] to enable the personalization variant. Use this early in sequence build, before you've committed to a send strategy — once you have reply data from a pilot, you can retire the weaker variants. For best results, run the five options past a colleague who matches your target persona and ask which one they'd open; gut-check beats guesswork at this stage.
