With a ZeroBounce account, you'll receive 1 Inbox Placement test every month (plus 1 Email Server Test, 1 Blacklist Monitor and 10 Email Finder queries).

Yes, we do have API available and you can validate your emails by using it. Here is a link to our documentation on our API: https://www.zerobounce.net/docs/email-validation-api-quickstart/
