Emails aren't sending

Work through these checks in order. Most campaigns that aren't sending fail at one of the first three.

1. Is the campaign running?#

On Campaigns, the status should be Active:

2. Can the mailbox send?#

1. Open Integrations.
2. Check that the mailbox shows Active: switched on, and not Access revoked.
3. Open it and use Test → Test connection, then Send test email.

See Test a mailbox integration.

If the campaign's mailbox was deleted, choose a new one under Email → Settings → Send from.

3. Is it inside sending hours?#

Emails go out only during the campaign's sending hours, in its timezone. When sending hours are off, they go out between 09:00 and 17:00 UTC. Outside those hours, planned emails wait.

4. Is anything planned?#

Open the campaign's Schedule tab.

• Nothing planned yet: today's plan is made when sending hours begin. Click Plan today (or Plan tomorrow once today's hours are over) to plan now.
• "Everyone in this audience has been contacted": the round is finished. See Resends and rounds.
• Lots of Skipped (undeliverable): many addresses would bounce. See A company has no email.

5. Did messages fail?#

Look at the Failed tab in the Outbox, or the campaign's Messages tab, for the reason.

To retry, open the message on the Schedule tab and click Retry now, or use Send now on it in the Messages tab.

If many fail at once, you'll get a Sending failures notification.
