List Hygiene

Also: List Cleaning

The ongoing practice of keeping your email list clean, removing invalid, bouncing, unengaged, and unsubscribed addresses so you only mail people worth mailing.

Why it matters

A clean list protects deliverability and sender reputation and keeps your metrics honest, while a dirty one quietly drags down everything you send.

What good looks like

Good hygiene means regularly removing hard bounces and chronically unengaged contacts, honoring unsubscribes immediately, and verifying new addresses.
