Upload or paste your contacts and instantly catch invalid, risky, disposable and typo addresses before they hurt your deliverability.
The checks above run free on this server and remove most bad addresses. To additionally confirm that each specific inbox truly exists (catch-all, spam-trap and real-mailbox detection), connect a verification provider's API — ZeroBounce, NeverBounce, Kickbox or Bouncer. The engine has a provider-agnostic hook ready: add your own API key and deep verification runs automatically on addresses that pass the in-house checks. Status: not configured.
