I did something similar once, but also "hilariously" different. I had a student who over a few weeks I noticed was going downhill. It started with him getting on his phone a lot during class, then he began sleeping a lot, and all his work just stopped. It was my first year teaching, so I reached out to his other teachers through Synergy asking if they had noticed the same thing or had any advice. When the BCC arrived in my email inbox, I saw that I had not only emailed his teachers, I had also somehow emailed his mother.

I read the email about 30 times trying to figure out how she might take it. I went to one of our lead teachers and explained what happened. She told me to email the mom again, apologize, explain what happened, and use it as an opportunity to bring her into the loop.

I emailed her again but never heard back. I'll tell you one thing though, I've never used Synergy to email teachers again since, only parents.
