What do you mean by ordering SMS balance to send takeaway tips?

This requires the use of third-party tools. There are many backstage users, so you need to recharge your SMS. There was an experiment in the early stage. You can try, search SMS marketing directly in the seller's service. You can try it first, such as payment care, reminder, delivery notice, evaluation invitation and other functions are still very good. It has a certain effect, and also has a good effect on the management of its own members. Before some activities, you can set up group recommendation, which is more direct. I have used several models. But it's the same. You choose a relatively cheap SMS with stable system. Try a few more, many of them are free for you!

Thank you, I hope I can help you!
