DNS & MX Health Checker
Instantly analyze DNS records (MX, SPF, DMARC) to ensure your domain is properly configured and secure.
Why Check DNS Health?
Proper DNS configuration is crucial for email deliverability and website security. Our DNS Health Checker validates your MX, SPF, and DMARC records to prevent email bouncing and spoofing attacks.
Email Deliverability
Missing MX records or invalid SPF/DMARC policies can send your emails straight to spam. Use our tool to verify that your domain is authorized to send emails and trusted by providers like Gmail and Outlook.
Technical Insights
