MX Record & Mail Server Lookup
Inspect your domain's Mail Exchange (MX) records, priority preferences, host IP mappings, reverse DNS (PTR) validation, and verify SPF & DMARC authentication status.
Why Correct MX Records & Email Authentication Are Vital
Mail Exchanger (MX) records are foundational DNS entries that tell the internet where to deliver email addressed to your domain name (e.g. info@yourdomain.com). Without valid MX records, sending mail servers cannot establish a connection, causing emails to bounce back to senders with delivery failure errors.
Optimizing Email Deliverability for Gmail & Yahoo Requirements
In 2024, Google and Yahoo introduced strict email sender guidelines. To ensure your business emails land directly in the recipient's primary inbox rather than the spam or junk folder, your domain must meet three critical requirements:
1. Valid MX Host & Reverse DNS (PTR): The IP address resolving to your mail server must match its forward DNS name, proving the server is legitimate.
2. Sender Policy Framework (SPF): An SPF TXT record lists the authorized server IP addresses that are permitted to dispatch emails using your domain identity.
3. DMARC (Domain-based Message Authentication, Reporting & Conformance): Protects your brand against email spoofing and domain impersonation by dictating what receivers should do with unauthenticated messages.
