Email Verifier APIAn email verifier, or email checker, is a tool to validate that an email address exists and can receive emails. Verifying is important before contacting new recipients to avoid bounces and protect your sender reputation.
Hunter's Email Verifier does a complete check of email addresses, verifies if it appears publicly on the web and returns the sources.
The Email Verifier does the validation without sending an email, by directly connecting to the SMTP server.
This is the list of validations the Email Verifier performs:
The email addresses recently verified and marked "Valid" are safe to use. We usually observe a bounce rate lower than 1% for these email addresses.
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, the Email Verifier can't make sure the tested email address actually exists and returns the "Accept all" status.
These email addresses are less safe to use than the email addresses with the "Valid" status. To decide whether to use them, you need to evaluate the level of risk you're willing to take.
For moderate risk, we recommend selecting only the highest-quality email addresses by using the confidence score returned by the Email Verifier. For example, you can keep only email addresses with score higher than 80%.
