Verify Your Domain

Ensuring your domain's email authentication records are correctly configured is crucial for email deliverability and security. We provide a free tool to help you verify your DMARC, SPF, and DKIM records.
Check Domain Health

How it works

Our domain checker tool automatically retrieves your domain's DNS records. It specifically looks for:
  • DMARC: Checks for the existence and validity of your DMARC policy.
  • SPF: Verifies your Sender Policy Framework record to ensure authorized IPs are listed.
  • DKIM: Attempts to retrieve common DKIM selectors to check for proper signing configuration.
The tool will highlight any syntax errors, missing records, or potential misconfigurations that could impact your email delivery.

Manual Verification

If you prefer to check your records manually using the command line, you can use the dig tool.

Checking DMARC

To check your DMARC record, query the TXT record for _dmarc.yourdomain.com:
dig +short TXT _dmarc.example.com

Checking SPF

To check your SPF record, query the TXT record for your root domain:
dig +short TXT example.com
Look for a string starting with v=spf1.

Checking DKIM

To check your DKIM record, query the TXT record for your DKIM selector. You either need to know your selector or try common ones like "default" or "selector1":
dig +short TXT selector._domainkey.example.com
Look for a string starting with v=DKIM1.
