Question 1

How does email validation work?

Accepted Answer

Our email validator returns a confidence score for any email address in under two seconds. No emails are sent to the recipient — results are based entirely on signals we can observe externally.

Question 2

Can I validate multiple emails at once?

Accepted Answer

Yes, our bulk email validation feature allows you to validate up to 100 email addresses at once. Simply paste your email list (one per line) and get instant validation results for all addresses.

Question 3

Is the email validator free to use?

Accepted Answer

Yes, our email validator is completely free to use. You can validate individual emails, bulk validate up to 100 emails, and discover emails by name and company domain without any cost.

Question 4

Can I find someone's email address using their name?

Accepted Answer

Yes, our email discovery feature allows you to find email addresses by entering a person's first name, last name, and their company domain. We test common email patterns to discover valid email addresses.

Question 5

Does the validator have an API?

Accepted Answer

Yes, we provide a free REST API for email validation. The API supports single validation, bulk validation, and email discovery endpoints. No authentication is required and CORS is enabled for easy integration.
