The Postcard Manager module is a great way to have an eCard or Evite feature on your site. You can use this to have the option for people to invite a friend to an event or a service, to participate in a discussion, to listen to a recent sermon, etc. Add images and custom text with a few simple clicks.

This feature is included with the Pro plan or can be added to the Lite or Plus plan for $50/year or $5/month.
