Mailbox sending limits

Each mailbox carries its own limits, shared across every campaign it sends for.

Steps

1. Go to Email Accounts.
2. Click the daily limit on the mailbox row to open Daily sending limit.
3. Enter the New limit (emails/day). The popover shows Limit, Sent today and Remaining.
4. Save.

Hourly limit is set when you connect the mailbox and can be adjusted from the account detail.

Recommended values

30 to 50 campaign emails a day for a warm mailbox on a healthy domain. Scale by adding mailboxes, not by raising one mailbox's limit.

Important notes

• The daily limit maximum is 2000, but using anything close to it on cold outreach is a reputation risk, not a feature.
• Campaign limits and mailbox limits both apply — the tighter one wins.
• The Email Accounts page shows a Daily sending capacity bar for the whole workspace.
