There is a bunch of smarts you can do with facebook advertising.

Not many people are aware, that you can upload your email lists, as private lists, to facebook.

Facebook matches them for you, and for the US its common to get 70% matching, or more with B2b.

After you’ve uploaded the list, you can use facebook marketing to get to those folk.

PLUS you can then segment the advertising, based on all the demographic info facebook has on your users in your private list.

THEN you can expand the advertising to people LIKE your private lists.

So if you arent processing your email lists through facebook, you are missing HUGE opportunities for smart marketing.
