Email Tools
Is your email domain configured correctly?
Check your domain’s public email DNS settings for Microsoft 365, Google Workspace, or Hosted Exchange—all in one place.
Email platform DNS checker
Enter your email domain and select your email platform to check MX, SPF, DMARC, and applicable Autodiscover records for potential configuration issues.

These checks identify publicly observable DNS settings that may need attention. A passing result does not guarantee successful email delivery or validate every provider-specific requirement. Share your support report with True Synergy Networks if anything looks unusual.
Public DNS records are retrieved through a third-party DNS resolver. Results may reflect cached information. DKIM validation requires a specific selector and is not included in this basic platform check. No DNS settings are modified.
Understand your results
MX & Mail Routing
MX records determine where incoming emails are delivered. Incorrect records can prevent messages from reaching your mailboxes or direct them to the wrong provider.
SPF & DMARC
SPF identifies authorized email senders, while DMARC helps protect your domain against spoofing. Missing or incorrect policies can affect email security and deliverability.
Autodiscover & Configuration
Autodiscover helps compatible email applications locate their mailbox settings. Requirements vary by email platform, and some configurations may need verification by TSN.
