Problem
The campaign is Active, the queue has messages, nothing goes out.
Possible causes
- You are outside the sending window right now
- The daily limit is already reached for today
- Every assigned mailbox is warming, paused or in error
- No mailbox is assigned to the campaign
- All remaining recipients are suppressed or already stopped by a stop rule
- Every assigned mailbox requires attention
How to check
- Compare the current time in the campaign's timezone with its window.
- Campaign → Queue: how many scheduled, and for when?
- Campaign → Email Accounts: is at least one mailbox Active?
- Email Accounts page: any Errors or Alerts?
How to fix
- Wait for the window, or widen it.
- Fix or add mailboxes using the action shown in mailbox details.
- Raise the daily limit only if the mailboxes can genuinely support it.
When to contact support
Window open, mailboxes Active, queue full, and nothing has moved for several hours.
