Connect
- Sign in with Google or Microsoft: fastest and safest. No password is stored, and you can revoke access any time from your Google or Microsoft account.
- Any other host (SMTP and IMAP): enter the server settings and an app password. It's encrypted before it's stored and never shown again.
Go to Mailboxes → Add mailbox. Each mailbox can have its own signature (plain text) and sending window.
Daily limit and ramp-up
A mailbox sends 40 emails a day by default (up to 200); 30 to 50 is safe for most mailboxes. New mailboxes start at 20% of their limit and reach 100% over 21 days, and emails go out a few minutes apart.
The ramp-up paces volume only. For inbox placement, pair the mailbox with a dedicated warm-up service. Need more volume? Add mailboxes rather than raising limits: campaigns rotate leads across them.
Replies and bounces
We check for replies every few minutes over IMAP once the mailbox sends campaign email. A reply stops the lead's sequence and lands in the inbox. Bounced addresses are marked so they're never emailed again.
How many mailboxes
Each LinkedIn account seat includes mailboxes: 1 on the trial, 2 per account on Pro and 3 per account on Agency.
