The Dos and Don'ts of IP Warming

IP warming should start with clean, engaged recipients and increase volume gradually while bounce, complaint, and engagement signals remain healthy.

Do start clean

Verify the initial audience. Start with recently engaged contacts. Increase volume only while metrics stay healthy.

Don’t blast cold lists

Avoid purchased lists and long-dormant segments during warm-up. Pause growth when bounces or complaints rise.
