Email Trust Center

Understand and improve trust in your email domains

Email Trust Center helps security teams review email authentication, understand their sending environment and investigate domain-trust risks. Use the findings to prioritise improvements across your email ecosystem.

From findings to action

Connect authentication posture with practical follow-up

Identify configuration issues, review sending activity and understand which domains or services need attention. Use that context to plan changes with the teams responsible for email and DNS.

What Email Trust Center monitors

  • Email authentication records (SPF, DKIM, DMARC and related DNS)
  • DMARC reports sent by receiving mail systems
  • Services seen sending email for your domains
  • Lookalike and impersonation domains

What your team does with it

  • Investigate failures and unknown senders
  • Plan DNS and policy changes with the teams responsible
  • Move towards appropriate DMARC enforcement
  • Report posture and progress to leadership

Monitoring shows what is happening. Changes to DNS records, mail flow and policy are made by the teams responsible for them.

DNS records

Domain trust monitoring

Monitors the DNS records that govern email trust and flags changes, expiries and exposures for review.

  • SPF, DKIM, DMARC, BIMI, MX and related records
  • Change detection
  • Expiry, MTA-STS and TLS-RPT checks
  • Subdomain-takeover exposure

Domain trust score

A starting point for investigation

Four weighted sub-scores (authentication, infrastructure, threat exposure and operational health) roll up into a single 0–100 score, recalculated as your posture changes. Review the factors behind it; it is not a certification that a domain is safe.

Vendors send email in your workflows every day. Email Trust Center can extend trust monitoring to the supplier domains you choose.

Vendor domain trust monitoring

Track the authentication posture and trust score of the supplier domains you add.

Lookalike vendor alerts

Flags typosquat and homograph domains that imitate your suppliers.

Supplier onboarding checks

Check SPF, DKIM, DMARC and infrastructure for a new vendor domain.

FAQ

Frequently asked questions

What is Email Trust Intelligence?
Email Trust Intelligence brings together information about email authentication, sending sources and domain-related risks. It helps teams understand their environment and decide what needs investigation or improvement.
Does DMARC stop every impersonation attempt?
No. DMARC helps receiving systems evaluate messages that claim to use a domain based on aligned email authentication. It does not address every lookalike domain, display-name impersonation or compromised-account message.
