I want to buy a short message group sending platform! What do you want to introduce?

It is best to use Huatang e-guest as a short message platform. I have used many platforms, and I feel that the gateway is better, but the card is not so good! However, there are too many SMS companies now. I don't know which is better. After using so much, I still think Huatang is good. Their products are more convenient to use and humanized in design! Sales and after-sales service personnel are very good, you can Baidu.
