# Verify SPF and DKIM Records

SPF, DKIM, and DMARC records tell receiving mail servers how to verify that email claiming to be from your domain is legitimate. Misconfigured records mean your legitimate emails land in spam, or worse, anyone can send email pretending to be you.

The lookup_dns skill retrieves your TXT records so you can verify SPF, DKIM, and DMARC are set up correctly. Check that your SPF record includes all your sending services, that DKIM selectors resolve properly, and that DMARC policies are in place.
