The world’s most thorough email validation tools

Our email validation tools make it easy to verify and clean your lists, ensuring your messages reach your audience every time.

Email Bounce Validator

Our email validation software tells you which emails will bounce. Scrub your list regularly so that your bounce rate never exceeds 2%.

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.

Toxic Domain Verifier

The API will help you identify domains known for abuse, spam, and bot-created emails. These domains are harmful to your sender reputation.

Gender Identification

We identify the gender of some emails in your list. Also, if you upload a list with first names, we’ll add the gender. If you don't have names, and we find a name, we’ll add it to your list.

Free Email Verifier

Use it anytime you want to quickly check an email address. It detects if the email belongs to a free domain and if it’s toxic or disposable. When available, we give you names as well as gender.

MX Record Detection

Our API will tell you if an MX Record was found for the domain we check. This way, you’ll know if a certain email address is genuine or fake.
