Prep for the big day (or night) with Paperless Post’s customizable invitations, RSVP tracking, and handy guest messaging.

What we love: Evoking the charming feel of an old-fashioned card, complete with a virtual envelope and sweet, decorative stamp. There are e-card templates for every type of celebration—baby showers, bar mitzvahs, birthday parties, and more.

Quick tip: Use Guest Tags to sort your attendees into categories, like “Out-of-Towner” or “Family,” to send messages to specific groups.

Meet the creator: Siblings Alexa and James Hirschfeld created Paperless Post after James threw himself a 21st-birthday party and wanted an invitation that combined the customizability of paper invitations and the ease of online communication.
