I'm considering going into doing email marketing, and have found that one of the ways that people build their lists is via Solo Ads.
However, when I see different solo ads vendors' sales pages, it almost never says anything about what niche it's for.
Is it presumed that it's only for the IM niche?
I'm just thinking that sending a solo ad to an IM list, and the ad is about a completely other topic it would not work.
What am I missing here?
