The Evite system serves as a party-planning device because it guides the user through a planning process, allows the user to manage their guest list, and alerts the user any time a person RSVPs for the event.
Invitations orders may take a month or more to process, and you will need to include time for sending out the invitations, as well as for the recipients to respond to the RSVPs.
Some couples are beginning to collect RSVPs via their wedding websites.
Words such as "cordially invited" and "your presence is requested" are typically found on formal notes, and RSVPs are usually required.
As an added bonus, you'll be pleasantly surprised to find out just how easy it is to keep up with RSVPs when you use an electronic inaction that can be sent via email.
