Projects / Online invitation card with guest replies
Web applicationOnline invitation card with guest replies
The guest opens an envelope and finds the card. They add the event to their calendar (Google, Outlook or a file) and reply online.
The need
An organizer wants to send an invitation online and receive guests' replies without chasing them one by one.
What I built
The guest opens an envelope and discovers the card. They add the event to their calendar (Google, Outlook or a file) and reply online. The organizer gets an email with each reply. Each guest has a personal link that greets them by name. Two templates: a wedding and a company party.
Demo: the names, the date and the venue are made up.
Try it in the demo
- Open the envelope, as a guest would.
- Add the event to your calendar: Google Calendar, Outlook, or a file for other calendars.
- Fill in the reply form: the email the organizer receives is displayed.
- Open this personal link: the card greets the guest by name.
Under the hood
What I checked
- Each guest has a personal link that greets them by name.
- Google Calendar and Outlook open with the event already filled in.
- A reply that doesn't say whether the guest is coming is refused. The text typed in is never interpreted as code.
- On desktop, the card stays fixed on the left while you read and reply on the right.
Simulated in the demo
- The email to the organizer is shown, not sent: in a live setup it goes to the client's own address.
