The teacher sent a mass notice. How should parents reply?

1, reply the receipt in time and do as required. If you are not clear, you can ask the teacher privately.

2. The news involves your children's problems. Thanks to the class teacher's concern and reminder, parents will actively follow up and deal with related problems simultaneously.

The news has nothing to do with children. Thanks to the notice of the class teacher, I will tell other parents to pay more attention and help them actively when necessary.
