Checking the existence of email addresses is simple
Atomic Mail Verifier is a unique program that checks email addresses for validity. Unlike other email verification software, our email verifier uses three levels of verification to ensure that you will never lose any valid email address.
After you load your mailing list or paste in email addresses for validation, our bulk email verifier begins to verify the addresses. All addresses are checked in multithread mode to speed up the entire process.
Our email verifier software checks the availability of the domain: i. e., it marks valid addresses like firstname.lastname@example.org or email@example.com, and marks nonexistent domains as invalid.
