Inbox rotation

Inbox rotation (also called mailbox rotation) means a campaign does not send from one address but takes turns across a set of mailboxes you have connected. The first prospect gets a message from mailbox A, the next from B, the next from C, and back to A. Each mailbox stays within its own daily limit, and the campaign’s total capacity is the sum of those limits.

It matters because volume is the thing providers watch most closely per address. A single mailbox sending a hundred cold emails a day stands out; four mailboxes sending twenty-five each look like four busy people. Rotation also contains damage: if one address develops a reputation problem, the others keep working while you investigate. The rule that makes rotation safe for conversations is consistency per prospect. The follow-up must come from the same address as the first email, or the thread breaks and the reader sees a stranger continuing a conversation they never had.

In Seegnals you pick the mailboxes for a campaign and their order; the campaign rotates through them in that order, each with its own daily limit. A prospect keeps the mailbox it started with, so follow-ups land in one thread, and gaps between messages are randomised.
