How it works

  1. 1

    Connect

    Authorise Securify once. We read your contacts — nothing else in your account is ever touched.

  2. 2

    We validate

    Each email runs through a disposable-domain check and a live SMTP probe. Clean, risky, disposable, or undeliverable.

  3. 3

    Tags land on your contacts

    Verdicts are written back as contact tags within seconds — segment on them immediately to suppress fakes.
