The weekly list-hygiene routine that saves your domain

The weekly list-hygiene routine that saves your domain

Everyone says: "Clean your list when bounces spike." Myth. By the time bounces spike, your sending reputation is already bleeding. Hygiene is a routine, not a rescue:

— Verify every new contact before it enters a sequence, not after.
— Suppress anyone who opened nothing across a full sequence — they're a dead address or a hard no.
— Pull catch-all domains into a slower, lower-volume lane.
— Re-verify any list older than 30 days; people change jobs constantly.

Deliverability isn't a setting you fix once, it's a chore you do Mondays.
