Google in the classroom

I have been using Gmail to communicate with parents and students, but there are many features that I was not aware of. Through this online class, I have learned how to add a signature and theme to personalize it. I'm looking forward to using the labels, filters and archiving messages to keep student/parent information organized and easy to access.  I also did not know about the unsend option, I have accidentally sent emails by mistake so this is good to know. I'm looking forward to continue to learn more options that gmail has to offer that can be used in my classroom.
