Looking for the Best Book Marketing Services – Any Suggestions?

Hey everyone,

I’m currently exploring options for book marketing services and wanted to tap into the community for some advice. I’ve recently come across Ottenheimer Publishers and was wondering if anyone here has any experience working with them? Are they just a publishing house, or do they offer marketing support too?

That said, I'm open to other recommendations as well. Whether it's a full-service agency or a specialized team that focuses on author branding, social media marketing, or Amazon promotions – I’d love to hear what’s worked best for you.

Any feedback, tips, or personal experiences would be greatly appreciated!

Thanks in advance!
