Response cards make keeping track of your guest list much easier.
The response card is inserted with a wedding invitation and is engraved or printed in the same style and paper stock as the invitation. Most people pre-address and stamp the reply envelope to make as easy as possible for guests to RSVP via mail. If you would like to receive replies via email or telephone, that's fine, just include the necessary information on the response card.
Regardless of the medium, RSVPs are essential tools to help you organize and monitor your guest list.
