need to selling and new advice

Hi there New to drop shipping here and need advice. I’ve set up my shop if I store for drop shipping with Zen drop. Currently I only have the free subscription of Zendrop and the things are not going so well. Zendrop Denied my fulfillment request and dont even have a phone customer service. Eventually my goal is to have a Walmart store Amazon store, tik tok shop right now I’m thinking of only drop shipping but might look into white labeling a product down the road.

I realize it’s not gonna be easy to Change my drop shipping partner and I have seen people talk about some options such as Zen drop, spocket, dsire, CJ…, When I think about a drop shipping partner I’m thinking about the following questions let me know if there are other factors I should consider and also please comment on the following questions:

– Which partner offers the most number of products to drop ship?

– Which partner can ship to customer the fastest?

– Which partner can add new products to the list faster?

– Which partner has more U S based drop shipping suppliers?

– Which partner offers the most automation services to make my life easier?

– Which partner is not nickling and diming for different services and does not have hidden cost?

– Which partner will be easy to switch from if needed down the road?
