MyRSVPLive provides telephone and online RSVP services to help people organize guest responses for weddings, anniversaries, birthday parties, corporate events, seminars, and other special occasions. Its service lets hosts create and manage guest lists from a computer, tablet, or mobile phone, while guests can respond and review event details online or by phone at any time.

Through a customized web portal, event organizers can track responses, manage guest counts, and collect useful information such as meal preferences and food allergies. Hosts can also share details including directions, transportation options, hotel recommendations, and gift registry information. An RSVP limit feature helps prevent guests from responding for more people than permitted, and the service can contact guests by phone if event details change.

MyRSVPLive is designed to reduce the time and expense associated with traditional RSVP methods, including postage and response cards. The company offers packages for events of different sizes, with account access provided for six months.
