What’s easiest FTP for a user? Can one EMAIL>ftp

I need a user (non-technical) to send a file to the website each month (where it’s incorporate into the website). They already email it to many people. Can one email to a website?
If not, what the easiest way of them posting it. I’ve thought of creating a network neighborhood on their PC … onto which they could drag&drop the file. Has anyone got any better ideas?
Thanks … Barry
