I heard about shoutcart long ago but I was not able to get in that platform because I was having my paypal account and then it got locked because of my changing name spelling on paypal. It was a lose for me and after that I not joined any site which accept paypal.
Geting account approved is also a tricky one since they almost rejected all the multi-niche account and all instagram account that have follower less than 10K,
But since it's all targeted they got so many advertiser especially in travel,fashion and luxury niche ,
I hope unboxed will have a same standart (or maybe higher) with shoutcart when accepting worker (influencer)
Unboxed is more better than that in their cooperation with their users and they are more friendly. They have many partners for advertisement which you can see on their website. They are the bigger brands which got partnership with unboxed.
