How Verifalia works

Our validation process
Your contacts will never receive an email message from Verifalia. We verify the existence of the individual mailbox, without ever sending a message to them.
Protecting your email data is our job. Your list will never be shared, sold, rented or even seen by anyone outside of our company. Read our Terms of Service for more details.
