The verifications are never totally sure, but we can guarantee that more than 95% of "Valid" email addresses won't bounce.
When you perform an Email Verification, the result might be "Accept all". Some email servers accept all the email addresses on the same domain name, whether they have actually been created or not. In this case, we can't make sure the tested email address actually exists and return the "Accept all" status.
To help you decide whether it's safe to use the email address, we also return a confidence score in percentage.
