Hi!
I don't recommend them at all.
I found Quuu Promote the beginning of this year and I opted-in so they charged my credit card $49 every single month. Then I realized after that if you don't use your credit, they will take it away after 60 days.
So what I did is promote a number of our blog posts but then they were REJECTING them. The sent one email and because they use an automated platform, Gmail puts them in Spam and you don't even realize it.
So in short, they took my credits anyway regardless if they see I tried to redeem it. Also, their platform is very bad, they don't tell you where the credits were used or had been taken away. See the attached screenshot.
I canceled the service but they still had my CC on file so they kept charging it and 10 months later, i saw I had a $400 charge from them. OH GEEZ!
Also, the results were not amazing. One of my posts went through a while back before I opted in on a monthly service.
In my own experience
