# Eventi

> Send and track event invitations over WhatsApp - delivery, opens, and RSVPs for every guest, with automatic reminders for anyone who hasn't replied yet.

Eventi is a platform for event organizers - weddings, birthdays, and reunions to start - to build a guest list, design an invitation, and deliver it as a real WhatsApp message with tap-to-RSVP buttons. No app or account is required for guests.

## Key facts

- Invitations are sent as WhatsApp messages via a real business number, not email or SMS.
- Guests reply with one tap: Yes, No, or Not sure yet - no page to load.
- Reminder rounds (up to three) only reach guests who haven't given a firm answer yet.
- Guest lists can be typed in manually or imported from a CSV or Excel file.
- Invitations can be an uploaded picture or a link to an external site.
- Eventi is free to start.
