Email Health Check
Check your domain's email authentication configuration. Analyze MX, SPF, DKIM, and DMARC records.
Frequently asked questions
- What is an email health check?
- An email health check analyzes your domain's email authentication records (MX, SPF, DKIM, DMARC) to verify they're correctly configured for secure email delivery.
- What is SPF?
- SPF (Sender Policy Framework) is a DNS record that specifies which mail servers are authorized to send email on behalf of your domain, helping prevent email spoofing.
- What is DKIM?
- DKIM (DomainKeys Identified Mail) adds a digital signature to outgoing emails, allowing recipients to verify the email hasn't been tampered with and comes from an authorized sender.
- What is DMARC?
- DMARC (Domain-based Message Authentication, Reporting & Conformance) tells receiving servers what to do with emails that fail SPF or DKIM checks, and provides reporting on authentication results.
- What does a good email health score mean?
- The score summarizes completed checks. A high score can still need review: read the findings for missing records, configuration problems, and checks that could not finish. Finding DNS records does not guarantee email delivery.
