How to write a mass SMS notification?

Good afternoon. I am the head teacher of this semester!

Please rest assured that your child is in this class. I also hope that everyone can understand and support each other in their future work!

For better home-school cooperation, I want to make some small requirements in the group:

1. The class group is a working group. Please abide by national laws and regulations, and don't make any illegal and disciplinary remarks among the masses.

2. You can't publish any advertisements for product promotion.

3. Some ideas and good suggestions about school work, class management and teachers' work, don't follow suit in the group. It is suggested to have a private chat with me so that I can report it step by step.

4. There are many things in class management. In addition, we should give consideration to teaching. Parents sometimes can't reply to the information sent by everyone in time, please understand.

5. In order to facilitate the later contact and avoid deleting the notes by mistake, please ask parents to change the notes: xxx parents/father/mother/sister.

In short, let's work together for a better tomorrow for our children!
