Know exactly
who is authorised
to send your email.
Authorize.email analyses the DNS and authentication infrastructure behind any domain — including SPF, DKIM, DMARC and MX — so you can see whether email is properly configured before it becomes a deliverability problem.
Give AI agents email intelligence.
Authorize.email gives AI agents a machine-readable interface for inspecting domains, understanding email authentication and verifying authorised infrastructure. Human users get the visual report. AI agents get the structured evidence through the Authorize.Email API.

Email doesn't just need to send. It needs to be authorised.
A domain can have a perfectly valid website while its email infrastructure is incomplete, misconfigured or completely absent. Authorize.email separates those systems and checks the actual DNS evidence.
Sender Policy Framework
Identify the servers and services authorised to send mail on behalf of a domain.
DKIM Verification
Inspect published DKIM selectors and determine whether a public signing key is available.
DMARC Policy
See whether the domain publishes a DMARC policy and understand the enforcement level.
Mail Exchange
Determine whether the domain actually publishes MX infrastructure for inbound email.
DNS Intelligence
Inspect the underlying DNS configuration and expose records that matter to email delivery.
