Quick answers to the questions that usually come up in a hurry.

​
My email isn’t arriving

Work through this checklist in order:
1

Is your sending domain verified?

Go to Settings → Domain. The domain must be Active. If it’s Pending verification or Verification failed, fix the DNS records and click Verify DNS. See Sending domain.
2

Are you hitting the warming quota?

New domains send under a daily limit that grows over time. If a campaign reached only part of its audience, check the warming status and daily quota on the Domain page.
3

Check the subscriber's status

Open the subscriber. Bounced, Complained, Suppressed and Unsubscribed contacts don’t receive mail. Pending confirmation means they haven’t confirmed double opt-in yet. See Subscribers.
4

Check consent for the topic

A campaign only goes to subscribers with valid consent for its topic. Check the subscriber’s Consents tab.
5

Review the pre-send analysis

Open the campaign and re-run Send: the pre-send analysis flags spam-score, content and configuration problems that hurt delivery.
6

Check the report

The campaign report shows delivered vs bounced counts. Hard bounces mean the address is invalid; soft bounces are temporary.

​
How do I stop or cancel a send?

It depends on the campaign’s status:
Always send a test email and review the pre-send analysis before scheduling. Once sending starts, there is no undo.

​
A subscriber didn’t get the double opt-in email

  1. Open the subscriber’s Consents tab and check the topic’s consent state.
  2. If it’s Pending confirmation, use Resend confirmation.
  3. Confirmations can expire. Resending issues a fresh link.
  4. Ask the subscriber to check their spam folder; if your domain isn’t verified yet, confirmation emails are more likely to land there.

​
My campaign shows Failed

Open the campaign for details. Common causes are a missing or unverified sending domain, no deliverable recipients, or blocked merge tags. Fix the cause and try sending again.

​
The assistant isn’t responding

  • “AI credits depleted”: you’re out of credits. Top up or upgrade under Settings → Subscription. See AI credits & plans.
  • “AI connection lost. Your progress is saved”: click Retry. Your work isn’t lost.
  • Offline: the chat needs a connection; builders fall back to the Editor while you’re offline.

​
Email sending is disabled

If your subscription becomes restricted (for example, a failed payment), sending is disabled until it’s resolved. Check Settings → Subscription.
