Built the way we'd want it built
Most tools for events are sold as software. You sign up, you learn an editor, you pick a theme, and you become the person responsible for maintaining a website in the weeks before your own wedding. That is a strange thing to hand someone who is already managing a caterer, a venue and a guest list.
RSVPs Invite is built on the opposite assumption. You send us what your event is, and we hand you back a finished link. There is no theme library, so no two pages we build look the same. There is no dashboard, so when your venue changes at the last minute, you message us and we make the change. The work stays on our side, which is where we think it belongs.
The same thinking runs through the guest experience. Nothing we build asks a guest to install an app or create an account, because every extra step between a guest and the reply button costs you responses. A link and a tap is the whole interaction.
An event is one day. It should not require a subscription, an app, or a login.
