Troubleshooting
| Issue | Solution |
|---|---|
| Authentication failed | Check the credentials are correct and still active in MailerSend. |
| Domain not verified | The sender domain has to be verified in EmailElement and in MailerSend. Check its SPF and DKIM records. |
| Run Test fails for one domain | That domain is not set up in MailerSend. Check it there, and check its DNS records. |
