Abuse Email Detection

These accounts have a history of marking emails as spam, and the next one could be yours. Our email list verifier detects them to protect your sender reputation.


Spam Trap Detection

Our email validator app identifies many spam traps that may be lurking in your list. Removing spam traps is essential to your email hygiene and inbox placement.


Disposable Email Check

These temporary email accounts self-destruct and end up bouncing. We run a thorough email list cleaning to weed them out for you.


Catch-All Email Check

ZeroBounce identifies catch-all domains so you can isolate them from your list. All these domains will return a “valid” result and you can later score them.
