Emails going to spam

Symptoms

• Recipients find your messages in the spam or junk folder.
• Some recipients never see messages from your domain.
• Email providers show a warning that the sender could not be verified.

Common causes

• SPF, DKIM or DMARC records are missing or wrong. See Email authentication records.
• The sending server is not authorized for the domain.
• Messages contain content or links that look like spam, or send large batches without warning.
• The recipient's provider has low trust in the sender.

Safe initial checks

1. Check the SPF record: dig TXT yourdomain.com +short.
2. Check the DMARC record: dig TXT _dmarc.yourdomain.com +short.
3. Send a test message to a mailbox you own, and open the message headers to see the authentication results.

Step-by-step solutions

1. SPF missing or wrong. Publish one SPF record that lists the authorized sending service. See Configure SPF.
2. DKIM not set up. Add the DKIM record shown in your email settings. See Configure DKIM.
3. DMARC missing. Add a DMARC policy, and start with a monitoring policy. See Configure DMARC.
4. Content. Remove unnecessary links and attachments, and send to recipients who asked for your mail.

How to confirm the issue is fixed

• The message headers show passing SPF, DKIM and DMARC results.
• Test messages reach the inbox for at least two providers.

When to contact support

Contact support if the records are correct, the headers show failures, and the problem continues after a few days.

Information to include in a support ticket

• The domain name, and the message header results.
• The sending address and the recipient provider.
