Common Errors

Error

Not delivering to a previously bounced address

Solution:

1. Click Sending → Suppressions
2. Choose the domain at the top
3. Search for the recipient's email
4. Select the recipient and click the trash icon on the right to remove them from the Bounces tab

Error

Recipient unsubscribed accidentally

Solution: switch to the Unsubscribes tab and remove the email from there.

Error

Unauthenticated email from a custom domain

Solution: set DMARC to none for the custom domain.

If you're using Gsuite email, you can configure DMARC to none here.

Error

Unauthenticated email from yahoo.com / hotmail.com / aol.com / outlook.com

Quick workaround: switch the sender email from yahoo.com, aol.com, or any other free-mail domain to your own domain or gmail.com.

For example, switch name@yahoo.com to name@gmail.com or name@your_domain.com.

FAQ

Q: I can't find the email in Mailgun logs at all — why?

Double-check that you have the correct domain selected in the logs view, and that your filter/date range covers when the email was actually sent. Logs are scoped to a single domain at a time.

Q: What's the difference between a bounce and an unsubscribe?

A bounce means the mailbox provider rejected the message (invalid address, full inbox, etc.). An unsubscribe means the recipient explicitly opted out. Both suppress future sends, but they're removed from different tabs — Bounces vs. Unsubscribes.

Q: How long does Mailgun retain sending logs?

Retention depends on your Mailgun plan. If you need to look up an older delivery, check your Mailgun plan's log retention window or reach out to Mailgun support directly.

Q: Can I search logs across all my domains at once?

No, the Logs view filters by one domain at a time. Make sure the correct domain is selected (Step 4) before adding your recipient filter.

Q: Why would DMARC cause an "unauthenticated" error?

If a domain has a strict DMARC policy (quarantine or reject) and the sending setup isn't fully aligned with SPF/DKIM, mailbox providers flag the message as unauthenticated. Setting DMARC to none relaxes enforcement while you sort out authentication.

Q: Do I need my own Mailgun login to check this?

Yes — you'll need access to the Mailgun account/dashboard tied to your sending domain to view logs and manage suppressions directly.
