Largest video file for Email?

I'm curious what's the largest size videos people are e-mailing these days and getting away with.
I want to include a trailer (output from Davinci) in a press kit that would be emailed to hundreds of media outlets and would rather send the actual video than just a link. Or is that a mistake? I've got my file down to 33MB as an H-265.mov so far but can shorten the trailer to cut that to 16MB if that would make a difference. I guess I could use an app like Handbrake to make it smaller, but I would rather keep this entirely in DR if possible.
