Frequently asked questions

Email validation is the process of checking whether the emails you’ve provided are real or fake.

A valid email address is an address that really exists and is currently used by its owner.

It doesn’t reach the addressee and returns to the sender. You may receive such notifications as ‘invalid email address’, ‘mail delivery failed’, ‘mail returned to sender’, etc.

Paste one or more emails into a special field on the Email Validator’s start page and launch the bot.

To find the email verification page on Botster, click on the green “Start bot” button at the top of this page.
