Understanding Your Results

Generates formatted DNS TXT and MX records (SPF, DMARC with Quarantine/Reject policy, Mail Exchangers) with 1-click zone file copying.

Practical Guidance & Next Steps

Google and Yahoo require all domain senders to have active SPF and DMARC records to prevent bulk email rejection.

What is this?

A domain management utility that builds standard email authentication DNS records.

How does it work?

1. Enter your root domain name. 2. Choose your email provider (Google Workspace, Microsoft 365, SendGrid, Custom). 3. Copy the generated SPF, DMARC, and MX records directly into your DNS manager.

Why use it?

Prevents phishing and guarantees your business emails avoid the spam folder.

Technical Scope & Calculation Limitations

Generates standard RFC-compliant DNS zone records for copy-pasting into domain registrars (Cloudflare, Namecheap, GoDaddy, Route53).

Frequently Asked Questions

DMARC (Domain-based Message Authentication, Reporting, and Conformance) tells recipient mail servers how to handle emails that fail SPF or DKIM checks (e.g. Quarantine or Reject).
