Use the result well

Three details that make a single check useful

  1. Send one complete email address

    Send the local part, the @ sign and the domain together, for example name@example.com. The domain is what selects the check route.

  2. Read registered

    The SaaS dashboard and the synchronous API return mailbox registration status in the same response shape.

  3. Use the returned result

    A successful response returns registered synchronously. Run a new check for an updated status, and obtain consent before contacting a person.
