Check your email deliverability instantly

Email deliverability is whether your emails actually reach the inbox — not the spam folder, not a bounce, not a silent drop into nowhere. It depends on a chain of DNS records and reputation signals that email providers check every time you send.

SPF tells receivers which servers are allowed to send on your behalf. DKIM proves your message wasn't tampered with in transit. DMARC ties them together and tells receivers what to do when checks fail. MX records control where incoming mail goes. BIMI lets you display your brand logo in supporting inboxes. And blacklists track IPs and domains with a history of sending spam.

If any of these are missing, misconfigured, or out of date, your emails may silently fail. Our free checker tests all six in one lookup. Enter any domain to see its full authentication status and find issues before your recipients do.
