Email Intelligence API

Decide on an email before you accept it.

Send an address. Get a single reachability verdict plus every signal behind it: syntax, MX, SPF, DMARC, disposable and role detection, and domain age — fast enough to run inline at signup.

Use cases

Every signal an inbox can reveal.

Stop fake signups at the door

The is_reachable verdict folds syntax, MX and disposable checks into one answer, so your form logic stays trivial.

Catch disposable and role inboxes

Flag throwaway domains and admin@ / billing@ role accounts that signal abuse or low intent.

MX and auth before you trust an inbox

MX presence, SPF strictness, and DMARC enforcement tell you whether the domain can receive mail and how seriously it authenticates senders.

Read domain trust at a glance

Domain age, registrar, SPF strictness and DMARC enforcement reveal freshly-registered or unauthenticated domains used in fraud.
