Email Deliverability Checker

Check SPF, DMARC, DKIM, MX, BIMI, MTA-STS and TLS-RPT in one report, with an overall health score and clear fixes. No signup, no API key, results are live.

What email deliverability depends on

When you send email, the receiving server decides whether to deliver, junk or reject it based on how well your domain is authenticated. SPF lists the servers allowed to send for your domain, DKIM cryptographically signs each message, and DMARC tells receivers what to do when SPF or DKIM fail - and where to send reports. Get these three right and legitimate mail reaches the inbox while attackers can no longer spoof your domain.

MX records route inbound mail, MTA-STS and TLS-RPT enforce and report on encrypted transport, and BIMI can show your brand logo next to authenticated messages. This report checks every one of those records at once and links to a dedicated tool for each so you can dig into the details.

FAQ

Which records matter most for deliverability?
SPF, DKIM and DMARC do most of the work. Publish all three, then move DMARC from p=none to p=quarantine or p=reject once your reports look clean.
Why does the report say no DKIM when I have it?
DKIM keys live under a selector you choose, so we can only probe common selectors. If you sign with a custom selector, open the DKIM tool and enter it directly.
Are MTA-STS, TLS-RPT and BIMI required?
No. They are enhancements for encrypted transport, reporting and branding. Missing them does not lower your core score.
Is my email valid but still going to spam?
Authentication is necessary but not sufficient - sending reputation, content and list hygiene also matter. Fix authentication first, then warm up sending.
