Email Security & Deliverability Tools

Email deliverability diagnosis

Comprehensive email deliverability analysis checking SPF, DKIM, DMARC, MX records, and blacklist status. Get an overall deliverability score with actionable recommendations.

Check email authentication

Check all email authentication mechanisms (SPF, DKIM, DMARC) for a domain in a single view. Identify configuration gaps and alignment issues.

Validate SPF records

Validate Sender Policy Framework (SPF) DNS records. Check syntax, DNS lookup limits, includes, and mechanisms for proper email authentication.

Validate DKIM records

Validate DomainKeys Identified Mail (DKIM) DNS records. Verify selector records, key types, and signing configurations.

Analyze DMARC policy

Analyze Domain-based Message Authentication, Reporting & Conformance (DMARC) policies. Understand policy enforcement levels and reporting configurations.

Check BIMI records

Check Brand Indicators for Message Identification (BIMI) DNS records. Verify logo availability and VMC certificate configuration.

Check MTA-STS configuration

Check Mail Transfer Agent Strict Transport Security (MTA-STS) configuration. Verify DNS records and HTTPS policy files for enforcing TLS in email delivery.

Check MX records

Check Mail Exchange (MX) records for a domain. Verify mail server configuration, priority settings, and connectivity to mail servers.

Test SMTP connection

Test SMTP server connectivity and capabilities. Check STARTTLS support, authentication methods, and server response codes.

Check blacklist status

Check if an IP address or domain is listed on email blacklists (DNSBLs). Monitor blacklist status to maintain email deliverability.
