Sending a save the date ecard
We know that sometimes the only planning you have done for an event may be just having a date (or a few possible dates). However, in order to snag future yes RSVPs from your guests you would like a way to tell them to save the date(s) in their calendar. In these cases, we suggest that you create an ecard. The ecard gives you more flexibility to add or remove information, as needed, for an event whose details have not yet been finalized. For example, you don't need to specify a date and time for an ecard since you can enter whatever information you want in the ecard message.
To create your 'save the date ecard', create an ecard, enter the possible dates or ideas for your event in the ecard message and, if needed, the ecard web page message. Then send it to your recipients or simply publish it. See Sending ecards to recipients and Publishing your event/ecard web page for more general information on sending/publishing an ecard.
When you decide on the specific details of your event, you can convert your ecard to an event invitation by clicking the "copy" icon for the ecard on your 'dashboard' and selecting "copy to an invite". This will copy the design, recipient list, message, etc...to an invite. With the invite, you will have event management features such as managing RSVPs, managing guest party size and more.
