This looks awesome. I have a bunch of thank you cards that I need to send (or rather, I should have sent 3 months ago), so I may give it a shot. My one concern is that you don't seem to get much control over formatting, as far as I can tell the entire message is just a big string.
Hi russell. Right now the formatting is pretty simple. You can use whitespace to break up the message or indent a paragraph. We're currently working on a card designer interface that will allow much more customization. If you have any specific requests please shoot me an email at cole (at) sendwrite.com.
