What Are the Best Book Marketing Services for New Authors?

Hey fellow writers,

I’m currently exploring different book marketing services to help get my book in front of the right audience. With so many options out there, it’s a bit overwhelming trying to figure out which ones are truly effective.

While doing my research, I came across Ottenheimer Publishers. I’m curious—has anyone here worked with them, particularly for marketing support? Do they offer any promotional services, or are they more focused on traditional publishing?

Also, if you’ve had great experiences with other marketing agencies or platforms, I’d love to hear your recommendations. I’m looking for something that offers a mix of digital visibility, social media outreach, and possibly Amazon promotion.

Appreciate any advice or feedback you can share!

Thanks
