Email health score
One-click check of a domain's SPF, DMARC, DKIM and MX configuration, with a weighted overall score and recommendations.
Usage
• Enter a bare domain without https:// (e.g. example.com)
• The overall score is a weighted sum of SPF, DMARC, DKIM and MX
• Results can be saved as a link, QR code or embed snippet
What is the email health score for
Email health checks summarize SPF, DMARC, DKIM and MX lookups and rule checks into a score and findings. Configuration queries do not send a test email or establish acceptance or inbox delivery.
It is handy for verifying a new domain's email setup, confirming the authentication chain after switching mail providers, troubleshooting messages flagged as spam, and sharing a clear email-security health report with clients or colleagues.
Frequently asked questions
How is the email health score calculated?
Each of SPF, DMARC, DKIM and MX is scored individually, then combined by weight into a 0–100 overall score and an A–F grade. Items that could not be evaluated (status 'Not evaluated') are excluded from the overall score.
If my score is low, what should I fix first?
Fix items marked 'Critical' first — usually a missing SPF/DMARC record or an MX that cannot receive mail — then address 'Warning' items such as a DMARC policy still at p=none or a short DKIM key. Recommendations are sorted by severity.
Can I share the report?
Yes. Click 'Save & share' to generate a report link valid for 30 days; you can copy the link, share a QR code, or embed it as an iframe in a web page.
Does the score guarantee security or delivery?
The score summarizes tested items under the current rules. It is not a certification, penetration test or delivery guarantee. Cite the time, findings and untested items with the score; missing data does not establish the absence of problems.
References and result limitations
Online results reflect the queried source or probe state at that time. Record the target, time, nodes or data source, and parameters when citing them. A single result does not establish continuous availability everywhere.
