For files in excess of 50mb, we ask that you use one of the many free file sharing services to create a "share link". So rather than needing someones email, or sending your email, you just upload your files, and then you generate a link which you can send to other users, and they can access the files directly via that link. You can paste a share link right into the communication thread within AirGigs.

Here are two popular free services that allow you to create "share links"

WeTransfer
