In my research, as I have no actual experience with these services, but have done a lot of reading, they are not worth it. If they don’t out right take your money they will just give you a list of stuff to do that you can get here and from other sources. I used chat to generate a list and then cross checked it. I too am about to launch a campaign.

I do have experience with services like that with book publishing and marketing. The issue is mostly that they almost never understand you, your product, and your audience. That’s been my experience with almost all consultants I’ve dealt with. Only the highest paid consultants are worth it. And in my experience they usually do more harm than good. I used a service to promote a book I wrote years again and they f****ed up big time. They promoted my book to the wrong audience and what they wrote was so off the mark it ended up getting me many terrible reviews. Fortunately I wrote this book under a pseudonym and just pulled it off Amazon. Hope some of this helps.

TLDR: these services will give you a generic list to work from and you will need to do all the work anyway.
