I've spent weeks trying to understand what a real book marketing service actually does beyond social media posts and email blasts and honestly, I'm still unclear. Every option sounds the same on paper. So I'm asking here which book marketing service (https://selfbookpublishing.co/book-marketing-services) surprised you with results you didn't expect, and what made their approach feel genuinely different? Where did you feel your budget was wasted? What do you wish you had asked upfront? Real answers only, please.
