Win back Email Subject Lines – How to write a great one?

Writing an effective win-back email subject line is the best bet to capture the attention of your lapsed customers. The goal is to evoke curiosity, remind them of the value you offer, and entice them to open the email.

Here are some email subject line best practices to guide you to write great and compelling ones.

  • Understand Your Audience – Not every lapsed customer is the same, and not every customer lapsed for the same reason. Find out why they left to craft content to target and persuade them.
  • Create urgency – Time-bound phrases like “Limited time offer”, “Last chance”, or “24 hours left”.
  • Personalize – Make the message sound like it is tailored to them. You can use the recipient’s name or reference their last purchase.
  • Keep It Short and Snappy – The subject line should be concise, ideally under 50 characters, to ensure it’s fully visible in most email inboxes.
  • Convey Value – Highlight a benefit or what they’ve missed out on. “Unlock new features now!” or “See what’s new since your last visit.”
  • Inject Emotion – Nothing is more persuasive than an emotion. Phrases like “We’ve missed you!” or “Feeling out of the loop?” can tap into feelings of nostalgia or FOMO.
