SPF / DKIM / DMARC checker
Inspect published email authentication records. This checks records at the entered domain; it does not validate SPF recursion, DKIM signatures, alignment, or inherited organizational-domain policies.
Open tool ↗DNS health checker
Review public address, mail, nameserver, authority, and certificate-authority records. Missing optional records do not necessarily indicate a problem.
Open tool ↗SSL certificate checker
Check the certificate presented by one public HTTPS endpoint, including hostname trust and expiry. Only port 443 is checked.
