Email domain check
Inspect MX, SPF, DMARC and DNS records for an optional DKIM selector.
No registration · Free
How to use
Enter a domain such as differline.com and optionally a DKIM selector. See the detected records and recommended next checks.
Record presence does not prove delivery or security. SPF includes, actual DKIM signatures and DMARC alignment are not validated. We inspect the entered domain, not organisational-domain DMARC inheritance.
