In every email list, there is a "Zombie Segment."

These are customers who bought once, 6+ months ago, and haven't engaged since. Most brands ignore them to chase new leads.

This is a mistake. These people already trust your credit card processor. They just need a reason to care again.

Do not send a "We miss you! Here is 20% off!" email immediately. It smells desperate and trains customers to wait for discounts.

Resurrect your dead leads with psychology, not just coupons.

🎯 Email 1: The "Have You Seen This?" (No Discount)
Highlight a major product improvement, a new bestseller, or a viral media mention that happened since they last bought.
Subject: "We've changed a lot since you left"
Goal: Curiosity and re-education.

🎯 Email 2: The Emotional Check-In
A plain-text email from the founder.
"Hey [Name], noticed it's been a while. I wanted to personally make sure you were happy with your last order. Reply and let me know?"
Goal: Guilt-free engagement and feedback.

🎯 Email 3: The "Break Up" Offer
Now, you offer the discount. But frame it as a goodbye.
"I don't want to clutter your inbox. Here is a $20 credit valid for 48 hours. If you don't use it, I'll take you off the list so we don't bother you."
Goal: Loss aversion.

You will either get a sale, a reply, or an unsubscribe. All three are better than a zombie subscriber costing you money.
