Check a domain's email DNS records

The Email DNS check looks up a domain's MX, SPF, DKIM and DMARC records and explains them in plain language. It flags common mistakes, such as multiple SPF records, more than 10 SPF DNS lookups or a missing DMARC policy, and each result appears as soon as its check finishes. DKIM keys are found by trying common selector names, and you can also check your own selector.

The lookup tabs now include Email next to DNS, so you can check the email setup of the domain you're already looking at without entering it again.
