Email DNS Checker looks up and analyzes the DNS records that control how email is sent and authenticated for a domain. Enter any domain and get an immediate report on its DMARC policy, SPF configuration, and DKIM selectors — including validation, provider identification, and plain-language guidance on what the records mean and whether anything looks wrong.
It's intended for developers, IT administrators, and anyone responsible for managing email for a domain. It's useful when setting up email authentication for the first time, troubleshooting deliverability problems, or just verifying that existing records are correct.
No account or login is required. Results are based entirely on live DNS lookups.
