Five Best Invitation Services
Pingg is an invitation and party management tool. Not only can you use the service to issue invitations via the web, email, snail mail, Facebook, Twitter, and text message, but you can also link invitations to a gift registry, charity registry, money deposit (for people contributing to the party), and a pot luck tracker to keep the dishes organized. Pingg also has tools for reminding guests about the event, sending additional messages to update them, and sending followup thank you notes when needed. The PinggPlus upgrade is $10 and is necessary if you need text messaging, want to remove ads from invites, need to invite more than 250 people, or want to create custom elements, like hosting the invitations on a custom web domain. more »
