An email verifier, or email checker, is a tool to validate that an email address exists and can receive emails.
Tomba Email Verifier does a complete check of email addresses, verifies if it appears publicly on the web and returns the sources.
The Email Verifier directly connects to the SMTP server without sending an email.
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 similar cases, the Email Verifier can't confirm if 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.
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%.
Yes, you can verify a list of professional email addresses with the Bulk Email Verifier.
When logged in, one verification costs one request, except when we fail to verify the email address.
With a free account, you can validate up to 50 email addresses per month. If you need more, please check the pricing for more information.
