Generate 10 Cold Email Subject Lines for a Persona

Generate 10 cold email subject lines under 5 words for a persona, mixing question, statement, and curiosity formats.

About this prompt

This prompt generates 10 short, no-clickbait cold email subject lines for a specific persona and email topic — mixing question formats, direct statements, curiosity gaps, and pattern-interrupt approaches. Use it before launching a cold email sequence when you want to test multiple angles before committing to a single approach.Subject lines determine whether cold emails get opened — this prompt generates a testing library rather than a single guess. Provide your [target persona], [topic of the email], and [what the email is about] to get 10 subject line variants under five words each, covering four distinct approaches: question-based lines that prompt curiosity, direct statement lines that lead with the benefit, curiosity-gap lines that create an incomplete thought, and pattern interrupt lines that break from the expected format. Use this over a single-subject-line prompt when you're running A/B tests or need to select the strongest opener before deploying a sequence at scale. Tip: the direct statement lines consistently outperform curiosity-gap lines in B2B contexts where buyers are senior — 'Your pipeline forecast process' typically beats 'The question your CRO is asking' because experienced buyers prefer specificity over intrigue.
