How it works

Three steps, then it runs itself

No implementation project, no onboarding call you have to sit through.

  1. 1

    Drop one endpoint into your form

    A single REST call. It works from any language and takes minutes to wire into a signup flow.

  2. 2

    Every address is checked in real time

    Syntax, domain, MX, role prefix, disposable provider, and a live SMTP handshake — before the user finishes signing up.

  3. 3

    Block, challenge, or allow

    You get a verdict and a risk score with the reason attached, and you decide what your form does with it.

Who it is for

Built for the way you actually work

Stopping fake signups

Throwaway addresses are the single biggest source of junk in a SaaS database. Block them at the door, not in a cleanup job later.

Protecting sender reputation

A bounce rate above 3% starts damaging your domain. Verification at the point of capture keeps the list clean by construction.

E-commerce checkout

A mistyped email means a lost receipt, a support ticket, and a refund request. One inline check prevents all three.
