Random something where a body text is replaced.

Kind of a silly idea, but where the body text is replaced on an email gateway, allow something random to be placed in there instead. For example:

Bitcoin price at time of sending

Unix fortune

Unix fortunes from the obscene file

Random stock quote

Current weather for a location

Something else that randomly changes through the day

Catfacts (You can't stop them!)

I realize that would defeat the purpose for many professional users, but for personal users such as myself that simply want a notification where otherwise, none was available, it's...well, not useful, but fun.
