    About this tool

    The MX Record Lookup tool queries DNS Mail Exchanger (MX) records for any domain name. It sorts results by preference priority number and identifies email providers (Google Workspace, Microsoft 365, ProtonMail, Fastmail, Amazon SES, Mailgun, SendGrid) automatically.

    How to use

    1. Enter domain name

      Type a domain name such as example.com or gmail.com.

    2. Select DoH resolver

      Choose your preferred DNS-over-HTTPS provider (Cloudflare, Google, or Quad9).

    3. Inspect MX records

      View mail servers sorted by priority along with detected mail service provider.

    Use cases

    Email setup verification

    Check whether your custom domain email service is correctly configured and pointing to your mail provider.

    Domain migration

    Confirm that MX records have propagated to new email servers during domain transfer.

    Common mistakes

    Mistake:Confusing priority numbers.

    Fix:Lower priority numbers indicate higher preference (Priority 5 runs before Priority 10).
