A red banner that says Email sending paused means too many of your emails bounced, were marked as spam, or were blocked. Waiting does not clear it. If the cause is permanent bounces, clean your list and resume it yourself from the banner. Any other cause needs a support review.

Read the reason

Click Learn more on the banner. The dialog shows the reason and the steps that apply to you. Reasons look like this: A pause stops campaigns, sequences, transactional email and test sends for that company. Your other companies keep sending. The thresholds are in Sender Health.

Resume after a bounce pause

1

Fix where the bad addresses came from

Verify the rest of your list with an email verifier and fix the form or import that let invalid addresses in. Addresses that already bounced are suppressed for you, so you do not need to delete them. See How do I see or remove contacts that bounced?
2

Open the banner dialog

Click Learn more. If the automated review is still running, wait a few minutes and reopen it.
3

Confirm and resume

Tick I confirm that I removed invalid or bounced contacts and reviewed the audience before sending again, then click Resume sending. Only the owner or an admin sees this button.
Resuming resets the bounce rate so it is counted from your next sends. Paused campaigns and due sequence steps are queued again.

When you cannot resume yourself

The dialog or a message tells you why:
  • “Sending cannot be resumed automatically for this account” or “Automatic resume limit reached. Support review required.” You already used the self-service resume, or it is turned off for the account.
  • “This pause reason requires a support review.” The pause is for complaints, temporary bounces, blocked emails or a manual hold.
  • “Email sending suspended.” The account is suspended and needs a review.
In each case message support with your account email, what caused the problem, and what you changed.

Other pauses that look similar

  • Monthly email limit reached. You used your plan’s allowance. See What counts as an email, and when does my limit reset?
  • One campaign paused, the rest still sending. A campaign pauses on its own when its own results are bad, for example Campaign bounce rate (34.6%) exceeded threshold (20%) after 52 emails. Clean that campaign’s audience, then click Resume on the campaign. See Campaign Pauses.
  • Temporary bounces or blocked emails. A mailbox provider is refusing your mail. Blocked Emails & Spam Placement shows how to find the provider’s reason and what to change before you ask for a review.
