Using email vs. snail mail to make/close deals

Hello!

I'm a new member and wanted to start out by thanking Gordon and Dien for providing such an amazing resource packed with so much great information and inspiration for those of us seeking a better way.

I purchased Jim Straw's "Finders Fees" course, and while the business model itself is very straightforward, I'm getting hung up on the logistics, particularly the method of communication used to initiate and close deals. Jim is adamant about the use of letters via snail mail and warns against using email to do these deals. Obviously, he was extremely successful, so I'm in no way doubting his methods, but I was wondering if anyone has experience doing deals by corresponding with buyers/sellers electronically and not using snail mail?

It would be great if this business model could be done from anywhere in the world using email, so if you were to travel abroad or decided to move overseas, you could still make deals with buyers/sellers in the U.S. (or anywhere for that matter) without having to mail actual letters.

Thanks in advance!
