Domain Mail Check

Check how a domain is set up for email, whether Gmail and Outlook are likely to accept its mail, and who it is registered with, from public DNS, free blocklists and registry data. Ask "will Gmail accept mail from example.com sent from 203.0.113.7?", "is DMARC set up correctly for github.com?", "check SPF and DKIM for example.com", "which mail provider does acme.io use?" or "when does openai.com expire?".
