Email verification is a means to ensure the message a sender wishes to send to an address gets delivered. The process works by validating the existence of an email address, so the message sent would not bounce or trigger anti-spam blocking mechanisms on the receiver’s end. Some security solutions may not be equipped to do that, and so the sender can end up on a spam blacklist. As such, email verification can help users avoid the hassle that results from being tagged as “spammers.” Any company that relies on email marketing would thus do well by integrating an email verifier into their existing security solution to ensure that not only are they protected from incoming threats but also that they won’t end up being seen by recipients as such.
