What is Sonfie?

Sonfie is an online RSVP platform and custom event website builder designed to help hosts invite guests, collect RSVPs, manage guest lists, and organize event details—all from one simple, shareable event website.

Instead of juggling paper invitations, spreadsheets, emails, and text messages, Sonfie brings everything together in one place using modern event management tools that make planning easier for hosts and effortless for guests.

Each Sonfie event includes a digital RSVP page where guests can respond, view event details, select meals, claim wishlist or gift items, and stay informed in real time.

Guests RSVP and Select Preferences

When guests RSVP, they can:

  • Confirm attendance and add plus-ones
  • Choose from available meal options
  • Select items from your wishlist or gift list
  • Leave notes or comments for the host

This transforms your page into a full event RSVP form builder, not just a yes-or-no response.
