DNS checker
Members onlyCheck any domain's email and website records in one go: SPF, DKIM, DMARC, MX, MTA-STS, blocklists and when the domain expires. You get a plain-English verdict on each, with the exact record to add if something's missing.
Only the domain name is checked. Nothing about your email is read or kept, and reports are deleted after 7 days.

What it checks
Who can send as you
SPF, DKIM and DMARC, read the way a receiving mail server reads them, with the fix spelt out.
Where your mail goes
MX records, the provider behind them and whether MTA-STS keeps mail encrypted on the way in.
Trouble spots
Ten blocklists, the domain's expiry date and the registrar, so nothing lapses quietly.
