Warmup and mailbox health

What warmup does and how to read the health score.

Every connected mailbox joins the warmup network unless you turn it off. It starts at 2 warmup emails a day and adds 2 a day up to 40. Receiving mailboxes open them, sometimes reply, and move them out of spam.

Health is the share of a mailbox’s warmup emails that reached the inbox over the last 14 days. It appears after at least five placements. Below 80, slow down: lower the daily limit and check the domain.

Warmup emails never appear in the team inbox. They do arrive in the mailbox itself.
