Which auxiliary tool can send messages on WeChat with one click?

Share a wave of experience with you and do a good job in answering questions. If it helps you, I hope to triple! !

More than 200 salespeople in our company send messages to their friends and groups every day. Our company has used "mass worry-free" for almost five years. Anyway, I started using it when I entered the company, which really saved a lot of time. I used to send messages one by one (silly crying).

Learn to use tools and do it yourself. You can't do anything in one morning. Everyone in our company has about 2 Wechat, and everyone basically has to maintain more than 3,000 friends.

Ps: WeChat friends must do a good job of labeling, so that the group sending efficiency is high.
