Check Your Domain's Email Health

A domain health checker is a tool that analyzes your domain's email configuration including SPF, DMARC, DKIM, MX records, and blacklist status. It helps ensure your emails reach recipients' inboxes instead of spam folders by identifying configuration issues and providing recommendations.

SPF (Sender Policy Framework) specifies which mail servers are authorized to send email on behalf of your domain. Without SPF, your emails are more likely to be marked as spam (up to 70% higher spam rate) and spammers can easily impersonate your domain for phishing attacks.

If your domain is blacklisted on RBLs like Spamhaus or Spamcop, most email servers will automatically reject or filter your emails. This severely impacts deliverability (often blocking 90%+ of emails), prevents messages from reaching recipients, and can damage your business reputation. Getting delisted can take days or weeks.

You should check your domain health weekly if you send regular emails, or immediately if you notice delivery issues. Regular monitoring helps catch problems early before they impact your email campaigns. Set up monthly checks at minimum, especially before important email campaigns.

DMARC is required by major email providers like Gmail and Yahoo (as of February 2024 for bulk senders). It protects your domain from spoofing and phishing attacks, and significantly improves email deliverability. Without DMARC, Gmail and Yahoo may reject your emails entirely.

A score of 90-100 is excellent (all records configured correctly), 70-89 is good (minor issues), 50-69 needs improvement (missing important records), and below 50 is critical (major deliverability issues). Aim for 90+ for optimal email performance.

Yes! You can check as many domains as you need. Simply enter a different domain and run the check again. This tool is completely free with no limits, making it perfect for agencies and businesses managing multiple domains.
