send a hand-typed letter, via email
Why send someone an email when you can send an email to a service that will type it out and send it to someone for you instead?
Introducing Type-O-Matic, an online service that will do just that. They turn your emails into letters by typing them out on vintage typewriters (and nice paperstock) that will catch your recipient's attention and show them thoughtfulness and care. The only catch is you might have to deviate from your standard "yo - what's up?" email style to make using this service worthwhile.
