Daily sending limit
The maximum number of messages one mailbox sends in a day, set low enough to look like a person rather than a machine.
A daily sending limit is a cap you place on each mailbox: once it has sent that many messages in a day, it stops and waits for tomorrow. The provider has its own hard ceiling, but the useful limit is far below it, at the level of a busy human who writes many emails but not hundreds.
The limit matters because mailbox providers judge behaviour. A new or quiet address that suddenly sends two hundred similar messages in an afternoon looks like a compromised account or a spammer, and the provider responds by filtering or blocking. Sending fewer messages per mailbox, spread across the day with irregular gaps, keeps each address inside the range the provider expects. If you need more volume, the answer is more mailboxes: 3 mailboxes at 30 a day is 90 a day without any single address standing out.
In Seegnals each connected mailbox has its own daily limit that you set, shown in the mailboxes list alongside its pace. A campaign rotates across the mailboxes you picked, in the order you picked, and a prospect keeps the mailbox it started with so follow-ups stay in one thread.
