About this prompt
This prompt produces five follow-up subject lines for SDRs and BDRs re-engaging a prospect who didn't open or respond to a first cold email. Each line indirectly references the prior outreach and creates a new hook — no lazy 'just following up' phrasing. Use it when you're building touch two or three of a cold sequence and need subject line options that don't sound like a nag.The follow-up email is where most cold sequences fall apart — reps either repeat the same subject line or use 'Following up...' phrasing that signals low effort and gets ignored. This prompt generates five alternatives that each create a fresh reason to open, without telegraphing that you've already been in the prospect's inbox. Provide [PROSPECT NAME/TITLE] and [TOPIC] so the output is grounded in the actual context of your initial email. Each line is capped at 45 characters to preserve mobile preview. Use this prompt for touches two through four of a sequence — not for the first email, which has its own subject line prompt (0043). For best results, pick the follow-up subject line that takes the biggest tonal or angle departure from your first email; consistency across touches trains prospects to ignore you.The prompt
