The check you just ran shows your current configuration. But DNS records change, sometimes without you knowing. A well-meaning IT change, a third-party provider update, or an unauthorized modification can break your email delivery overnight.
Configuration Drift
IT changes that accidentally break authentication
Provider Updates
Third-party services changing their SPF includes
Unauthorized Changes
Attackers modifying records to send as you
DMARCTrust monitors your DNS records continuously. When something changes, you get an email alert with exactly what changed and why it matters. No more surprises when customers complain their emails bounced.
Run a free email authentication check (DMARC, SPF, BIMI).
We will generate a shareable URL for your domain.

Showing domains checked by our users. All data is from public DNS records.
We analyze your domain's email authentication: DMARC policy and alignment, SPF record and includes, and BIMI logo/CV when present.
Healthy authentication improves delivery and blocks spoofing. Major inbox providers increasingly require DMARC and robust SPF/DKIM practices for senders.
This check shows a snapshot. With DMARCTrust, you get continuous monitoring of your DMARC reports and DNS records, with instant alerts when something changes.
