bad timing, {{FirstName}}?

re: {{previous subject}}
still worth a look?
picking this back up?
didn't want to assume
quick nudge on {{topic}}
last one from me, promise
bumping this up your inbox
did this get buried?
{{FirstName}} — good time or not?

Why it works: follow-ups fail when they sound impatient. These stay light and give the reader an easy out (“bad timing?”, “should I close this out?”), which lowers pressure and, counterintuitively, gets more replies. Reusing “re: {{previous subject}}” keeps the thread together so context isn’t lost.

Swap in

  • {{previous subject}} — paste your original line to keep one thread.
  • {{topic}} — the value point from your first email, restated briefly.
  • Space touches 3–5 business days apart; stop after the break-up line.
