JumboMail is more than just a file transfer platform for sharing large files, JumboMail is a communication tool as well. It's not just about sending the files to someone and forgetting about it, it's about connection with each other and sharing experiences.
When viewing the download page, you can comment on a specific file, or on the whole email. All you need to do is log into JumboMail or Facebook and leave your comment. Tell the sender how lovely his photos look, or Let other recipients know what image you like best.
