How it works
For each email submission, our tool connects to the email server, simulates sending a message, and verifies if the mailbox really exists. No actual email is sent.
Sending emails to invalid adresses results in hardbounces and low email open rate that get your future emails labelled as spam. Improve your deliverability and increase your email open and click rates!
