Speed of confirmation, stats were useful as a show off feature. I had considered using email but as with postal I didn't have everyones address (can't actually think of the last time I emailed friends), we had around 90% of peoples telephone numbers and so it became the logical mode of communication for this project.

I had thought about a phone call out with a prerecorded message to our guests and then collect their input via dtmf ;) But SMS was the easiest method for our needs, but it depends on what networks your guests use I guess.

I've seen many of my friends get married and it can be so expensive (tens of thousands) and for a single day!
