While looking at Invitation templates, I noticed one included two RSVP options. One was the traditional mail-your-reply, and the other said to reply by emailing or calling. Which do you prefer? I kind of like the idea of having guests email or call me instead, because nothing will get lost in the mail, I wouldn't have to deal with return envelopes and postage, and I would hear from them exactly who is attending without confusion.
Thoughts? 
*Update*- A third option is a postcard RSVP. So guests would fill out & mail a pre-stamped postcard included in invitation suite. This would skip the return envelope hassle.
