Email Health Checker
Free email health check and email health checker for your domain. This email domain health checker checks email health with a comprehensive email domain health check across MX, SPF, DKIM, DMARC, and reputation.
What Is Email Health?
Email health describes how well your domain is configured to send and receive email. It covers DNS records, email authentication (SPF, DKIM, DMARC), server connectivity, and reputation. A healthy domain is far less likely to have its email marked as spam or rejected.
What Does Email Health Check Test?
An email health check looks at the systems that determine whether your mail reaches the inbox:
- MX records - which mail servers accept email for your domain
- SPF - which IPs are allowed to send email for your domain
- DKIM - digital signatures that verify message authenticity
- DMARC - policy that tells receivers what to do with unauthenticated mail
- Blacklist status - whether your domain or IP is listed on DNSBLs
- SMTP & PTR - mail server connectivity and reverse DNS
- MTA-STS & BIMI - transport security and brand indicators
How to Improve Email Health
- Publish a valid SPF record and keep it within the 10 DNS lookup limit.
- Sign your mail with DKIM and verify the selector resolves correctly.
- Publish a DMARC policy and move from none to quarantine or reject over time.
- Make sure your MX records point to reliable mail servers and that PTR records match your sending hostname.
- Monitor blacklist status and sender reputation regularly.
- Consider adding MTA-STS and BIMI for stronger security and branding.
Common Email Configuration Problems
Receivers may treat your mail as suspicious. Check with the SPF Checker.
A p=none policy does not protect your domain. Use the DMARC Checker.
Being listed on a DNSBL hurts deliverability. Check with the Blacklist Checker.
Wrong MX records or missing PTR can cause mail to bounce or go to spam.
FAQ
What is a good email health score?
A score of 80 or above usually means your domain is configured well. Scores below 60 often indicate authentication or DNS problems that need fixing.
Why is my email going to spam?
Common reasons include missing SPF/DKIM/DMARC records, blacklisted IPs, poor sender reputation, and spammy content.
How often should I check email health?
After changing DNS records, and then monthly, is a good baseline. Check again if you notice deliverability drops.
