Best Book Marketing Services in 2025 – Who’s Actually Helping Authors Succeed?

[michaeladams]

Hi everyone!

I'm in the process of launching my book and want to make sure I'm investing in the right Best book marketing services—one that's not just flashy, but actually delivers results. With so many options out there, it's hard to know who's truly effective and trustworthy.

I'm looking for services that offer:

Proven marketing strategies (Amazon ads, email campaigns, influencer outreach, etc.)
Genre-specific experience
Transparent pricing and deliverables
Strong client testimonials or case studies
Ethical practices (no fake reviews or spam tactics)
Some names I've come across include BookBub Ads, Smith Publicity, BooksGoSocial, and Reedsy Marketing Services. But I'd love to hear from authors who've actually used these—or others—and can speak to their experience.

If you've worked with a marketing service that helped boost your visibility, reviews, or sales, please share your story. What worked? What didn't? Any red flags to watch out for?

Let's help each other make informed decisions and get our books into the hands of more readers.
