How to send shop notification SMS in groups?

I just saw this problem somewhere else. Don't we all use WeChat now? Does your company have no WeChat group? You can build a group, or everyone has received it. You can ask everyone to add your WeChat and send it to them in groups. You can add a label to everyone in your company with the help of software such as Reed Assistant, and employees can update the label when they leave and join. Every time you send a group message, you can send it according to the label or send it intimately, that is, bring the other person's name, so that the other person doesn't look like a group.

You can also set up multiple customer groups or send them according to group chat. It can be operated by mobile phone. It's simple.
