The cap
A mailbox's daily cap rises only while bounces and complaints stay low. It does not rise on a timer.

Every mailbox has a daily cap that rises only while bounces and complaints stay low. Rules you set pause a campaign or rest a mailbox before harm is done, and sending domains are checked.

A mailbox's daily cap rises only while bounces and complaints stay low. It does not rise on a timer.

Placement is tested with seed inboxes. When placement slips, the mailbox is rested. You can also set rules on hard-bounce rate, complaint rate, placement and blocklists.
