Email warm-up

Gradually raising your sending volume from a new domain or IP so providers learn to trust it.

In practice

Start with small sends to people who want your mail and increase over weeks, watching bounces and complaints. Rushing, or sending to an unchecked list at the start, damages the reputation you are trying to build.

Verification and sending

Verify before warm-up begins. Early bounces are weighed heavily because there is no history to offset them.
