Hi there and welcome to Just Answer. My name is Steve and I am one of the Canon experts here. I am in Maryland and have been helping customers like you on this site since 2005.
I'm sorry to hear about your issue - let's get started!
You can adjust the size, and the compression of your JPG image files. Both of these will reduce the file size.
To adjust this on the 4000D, go into the RED Shooting menu and look for Image Quality. There are (in order of size from Large to Smalll) two Large, Two Mediums and three Smalls.Select the one you want that best suits your email requirements.
Please let me know if you need further help. I'll be here.
All the best.
