Chapter 1 of 3 · Why bad addresses cost you
About this video
People change jobs. Domains close. Typos slip into signup forms. Send to those addresses, and the bounces drag down your sender reputation. Check them first, and you know which ones are safe to use.
Each address gets four checks: syntax, domain, mail server, and a live mailbox check. If a mail server won't give an answer, the result is unknown, and unknown is free.
This channel shows how each feature works, what each result means, and how to connect your tools.
