DNS Checker vs Domain Health

While our Domain Health tool analyzes your current DNS configuration and scores it, the DNS Checker specifically compares your records against the expected values for your email provider. Use DNS Checker when you want to verify your setup matches provider requirements.

Common DNS Issues

  • Missing SPF include - Your SPF record doesn't authorize your email provider
  • DKIM not found - The DKIM selector doesn't exist or is misconfigured
  • DMARC policy too weak - Using "none" policy provides no protection
  • Wrong MX records - Email may not reach your provider's servers

Supported Providers

The DNS Checker supports automatic detection of expected records for Google Workspace, Microsoft 365, and Zoho Mail. For custom setups, we still check record validity and best practices.
