Reveal your engagement through a romantic interactive surprise — then collect RSVPs and organize your wishlist in one place.
What Is A Hidden Promise?
A Hidden Promise is an interactive engagement announcement that invites guests to uncover a meaningful surprise. Through a simple, elegant interaction, guests reveal your engagement and are welcomed into the celebration.
Once the reveal is complete, guests flow naturally into your RSVP page, where they can confirm attendance and select items from your wishlist. It’s a thoughtful way to share your engagement while keeping planning details organized from the start.
A moment worth revealing — and celebrating together.
