New since the last launch: three free checkers. DMARC, SPF and MX. No signup, no card. Paste a domain and the record is parsed, not dumped: the DMARC policy and where reports go, the SPF all-qualifier and how many of the 10 permitted lookups you have spent, and which provider really runs the mail. Same DNS code that scores email and domains inside the API. A missing record says so; a DNS failure says that instead, because those are different answers.
