Email Deliverability Scanner & DMARC Checker
Check your domain’s SPF, DKIM, and DMARC configuration
Email authentication plays an important role in protecting your business from email spoofing and helping legitimate messages reach their destination. Use our free Email Deliverability Scanner to check your domain for the DNS records commonly used to authenticate business email.
Enter your domain below to scan for:
- DMARC – Helps protect your domain from email spoofing and phishing while defining how receiving mail systems should handle messages that fail authentication.
- SPF – Identifies the mail servers and services authorized to send email on behalf of your domain.
- DKIM – Uses digital signatures to help receiving mail systems verify that a message was authorized by your domain and wasn’t altered in transit.
Why Email Authentication Matters
Improperly configured or missing email authentication records can contribute to legitimate messages being sent to spam, rejected by receiving mail systems, or make it easier for attackers to impersonate your business.
SPF, DKIM, and DMARC work together to improve email authentication and give domain owners greater control over how their domain is used for email.
*This tool only checks if the proper records exist. To ensure they are correct, you should have someone familiar with email system configuration analyze them. If you are looking for someone to do this, contact us about our managed service options.
