Campaign is active but nothing is sending

Diagnose an active campaign with no outgoing mail.

Updated Sep 10, 2026 1 min read

Problem

The campaign shows Active and the queue has scheduled messages, but nothing goes out.

Possible causes

  • Outside the sending window
  • Daily or hourly limits already consumed for the period
  • All assigned mailboxes are warming, paused or in error
  • No mailbox assigned
  • Every assigned mailbox requires attention
  • Every remaining recipient is suppressed or stopped

How to check

  1. Current time versus the window, in the campaign's timezone.
  2. Campaign → Queue: counts by status and the scheduled times.
  3. Campaign → Email Accounts: at least one Active mailbox.
  4. Email Accounts page: Errors and Alerts tiles.

How to fix

Open the window, fix or add mailboxes, or accept that limits are pacing you.

When to contact support

Window open, mailboxes Active, queue full, nothing sent for hours.
