So, I came across real "snail mail"

The people at 'Boredom Research Labs’ have designed ‘the world’s first webmail service using real live snails.’

Yes you read that correctly.

Actually, the thinking behind the project, or at least post-event justification, is to slow technology down, as a form of discipline or meditation. You send your email in the normal way, and this is then stored in a device in the snail’s tank. When a snail, fitted with a RF chip, crawls by, the data is loaded onto the chip. When that snail eventually passes another device, the information is passed from the RF chip, and the mail is delivered as usual. You therefore have no idea when your message is going to eventually be delivered.

Utter fruitloops, completely mad, and the rest of it. But rather an interesting gesture.
