Email list management - and how to do it (with or without AI)

How to manage your email list effectively

Good list management is really about removing dead weight before it drags down deliverability and Klaviyo costs.

1. 1.

   Identify chronically unengaged subscribers - No opens or clicks in 90-180 days signal risk to sender reputation.

2. 2.

   Segment by decay trend, not just status - A subscriber sliding from active to quiet needs different treatment than one dead for a year.

3. 3.

   Cross-reference with purchase history - Someone who bought recently but doesn't open email may still be a valuable customer.

4. 4.

   Draft a sunset or re-permission campaign - Give unengaged users one last chance before removing them from paid sends.

5. 5.

   Track list size vs engaged list size monthly - A shrinking total list with rising engagement rate is a healthy sign, not a bad one.

6. 6.

   Suppress or remove after the grace period - Cutting dead weight improves open rates and lowers your Klaviyo tier cost.

Takeaway: Run this audit monthly rather than reacting when deliverability drops - hygiene is cheaper as prevention than as cleanup.
