Email DNS determines where your mail is delivered and how it is authenticated. An email-focused DNS lookup helps verify MX, SPF, DKIM, and DMARC records in one workflow.
Email setups commonly depend on MX for receiving mail, SPF for sender authorization, DKIM for signing, and DMARC for policy and reporting.
Use email DNS checks when setting up business email, changing providers, fixing delivery issues, or improving domain trust.
Check that your MX records point to the correct provider and that SPF, DKIM, and DMARC are published consistently for your sending services.
Typical errors include wrong MX priorities, multiple SPF records, missing DKIM selectors, and publishing DMARC before the underlying email setup is ready.
