How to Fix DKIM Issues in Gmail for Better Email Deliverability

DomainKeys Identified Mail (DKIM) is an essential email authentication method that helps protect your domain from spoofing. If you're seeing DKIM errors in Gmail, follow these steps to resolve them:

1. Log in to your domain provider and locate your DNS settings.
2. Add or update the DKIM TXT record provided by Google Admin Console.
3. Allow DNS changes to propagate (can take up to 48 hours).
4. Verify DKIM status in Google Admin Console under Apps > Google Workspace > Gmail > Authenticate Email.

Proper DKIM setup ensures your emails are less likely to be marked as spam and improves your sender reputation.
