One of the best ways to avoid an email blacklist is to provide a useful and relevant email experience for your customers. You're less likely to be reported as spam if your contacts engage with your emails. Plus, you'll receive a bump in your email metrics.

Most major ISPs maintain their own internal blacklists. In some cases you can query them; in others, you can't. For example, Gmail Hotmail (now Outlook.com) and Yahoo maintain their own internal blacklists within their spam filtering technology.

Blacklisting is the name for the practice of identifying IP addresses associated with spam content and blocking content from those addresses. The point of blacklisting is to prevent unwanted spam content from untrustworthy sources.

I realized my roadrunner email being a set up as a POP3 account was a problem and needed to be changed to IMAP.

FIRST I did a backup: In Outlook 2013, hit "File" in upper left hand corner
