Free Email Tool
Check MX, SPF, DMARC, and BIMI records for any domain in one click.
Check all critical DNS records for a sending domain: MX, SPF, DMARC, DKIM presence, and BIMI. Quick deliverability pre-flight check.
A properly configured email-sending domain requires at least four DNS records to work correctly: MX records for receiving replies, an SPF record authorizing senders, a DKIM record for signing, and a DMARC record for policy enforcement. This tool checks all of them simultaneously, giving you a complete picture of your domain's email DNS configuration in a single check.

| MX Records | yourdomain.com | Receiving email |
| SPF TXT | yourdomain.com | Authorizing senders, anti-spoofing |
| DKIM TXT | sel._domainkey.yourdomain.com | Email signing, required by Gmail/Yahoo |
