How to send a notice in a group without notice?

Generally, it is indicated at the end of the notice that no further notice will be given.

To notify things in a group, you can use the following format:

Attention, team members Here is an important notice:

We will have a team meeting in the conference room at 3 o'clock this afternoon. Please arrange the time in advance and attend on time.

If there are any changes or problems, please inform us in the group in time.

Thank you for your cooperation!

The above is a simple example, you can adjust and modify it according to the actual situation. When notifying, try to be concise and to the point, so that the team members can understand and accept it quickly. If you need to explain in detail, you can gradually expand it in the subsequent chat.
