How to Check MX Records
MX records define which mail servers receive email for a domain. Use this workflow before acquisitions, migrations, or deliverability troubleshooting.
Step 1: Open the MX lookup tool
Navigate to the MX record lookup hub or enter your domain on the homepage search.
Step 2: Review priority and exchange values
Lower MX priority numbers route first. Confirm multiple exchanges exist for failover if mail is critical.
Step 3: Cross-check SPF and DMARC TXT records
Use the SPF/DMARC checker or full DNS report to ensure mail policy TXT records align with MX hosts.
Step 4: Document baseline before transfers
Save MX priorities and TXT policies before registrar or hosting migrations to detect drift later.
