How can I bypass snail mail (use email) to generate a physical letter that can be sent to a physical address?

Question

Or, is there another method I can use.

This is intended for overseas mailing.

*I do not have a fax number to use*

Answer 1

If you email it somewhere that magically turns it into a a physical letter, with a correctly addressed physical envelope, where do you keep it safe while you physically travel there and put it in the physical mailbox?
