I have a personal development blog, but the list I want to build is in the IM niche. Would I be able to have an opt-in on the blog for say: "Want to start making money online? Join are newsletter to learn how. _________" (just an example off the top of my head)
Would this work? IM falls under personal development, but would this be worth doing since personal development is such a broad term.
Opinions please, thanks.
