About this prompt
This prompt generates ten cold email subject lines for a specific topic or pain point, following strict format rules: under 8 words, no ALL CAPS or clickbait, no overused openers, with at least three curiosity-based options and two that reference a specific company signal. It's for SDRs and AEs testing subject line variants in a sales engagement platform. Use it when starting a new outbound campaign or refreshing a sequence where open rates have declined.Subject lines are the only part of a cold email that 100% of recipients see — and most reps write them last, in under a minute, as an afterthought. This prompt treats subject line generation as a structured task with real constraints that mirror what actually works in B2B outbound: brevity, specificity, and pattern interruption. Fill in FILL IN TOPIC OR PAIN POINT with the core angle of your email (e.g., sales rep ramp time at fast-growing SaaS companies, ERP implementation failure rates). The prompt produces ten options across different angles — curiosity-based, signal-based, and direct — giving you a test set rather than a single guess. Use this prompt to build a subject line bank when launching a new campaign, then A/B test in your SEP tool to identify what resonates with your specific ICP before committing to one across the full sequence. A signal-based subject line referencing a specific company trigger (recent funding, new job posting) should be paired with a personalized email body — don't use a signal-based subject line on a generic email.The prompt
