Gmail, Outlook/Hotmail, Yahoo, GoDaddy, and some other major mailbox providers maintain their own blacklists to stop spammers from messaging their users. Mailbox providers reference blacklists to identify bad senders and decide where to place their emails: in the spam folder, or block them completely.

In order to protect their users from unsolicited emails, mailbox providers developed blacklists to flag bad senders, somewhat like a blocked senders list. Likewise, safe senders with proper email authentication, positive reputation, and great list management, should have better deliverability and inbox placement. If you have bad sending practices, it can lead to serious deliverability problems and ultimately land you in the spam folder. Your sender reputation and email performance are directly dependent on your sending workflow.
