# Eventi - full reference > Send and track event invitations over WhatsApp - delivery, opens, and RSVPs for every guest, with automatic reminders for anyone who hasn't replied yet. ## What Eventi does Eventi lets an event organizer (couples planning a wedding, parents planning a birthday, anyone organizing a reunion) do four things: 1. Create an event with a name, date, and venue. 2. Build an invitation - either an uploaded picture, sent as the actual WhatsApp image, or a link to an external site. 3. Add a guest list - typed in manually, or imported from a CSV or Excel file with a preview before anything is saved. 4. Send the invitation over WhatsApp from a real business number, with tap-to-RSVP buttons (Yes, No, Not sure yet) built into the message. ## How delivery and RSVPs work - Delivery, read receipts, and RSVP status update live in the organizer's dashboard. - A guest's tap on a reply button updates their status immediately. - If a guest says Yes and was invited with more than one seat, Eventi asks a short follow-up for the final headcount. - Reminder rounds (configurable, up to three) are sent on a delay after the previous round. A round is skipped for any guest who has already replied Yes or No - "Not sure yet" and no-reply both still receive the next round. ## Pricing Eventi is free to start - no credit card is required to create an event and send invitations. ## Sign in https://app.ueventi.com/login ## FAQ Q: Do my guests need to install anything? A: No. Invitations arrive as a normal WhatsApp message. Guests tap Yes, No, or Not sure yet right inside the chat - no app to install and no account to create. Q: What can the invitation look like? A: Either a picture you upload - sent as the actual WhatsApp image - or a link to your own site, like a custom wedding page. Q: How do reminders work? A: You configure up to three reminder rounds with a delay between each. A guest who has already replied Yes or No is skipped automatically - only guests who haven't given a firm answer get a follow-up. Q: Can I import my existing guest list? A: Yes. Import a CSV or Excel file and we'll match names, party sizes, and phone numbers, with a preview before anything is saved. Q: Is Eventi free to start? A: Yes, you can create your first event and start sending invitations without a credit card. Q: Is Eventi a guest list app? A: Yes - Eventi is a guest list app and WhatsApp invitation tool in one. Import or build your guest list, send the invitation, and see delivery, RSVPs, and reminders for every guest from the same dashboard. ## Blog posts ### How Eventi sends invitations over WhatsApp https://ueventi.com/blog/how-eventi-sends-whatsapp-invitations Product - Jun 2, 2026 - 3 min No app to install, no account to create.
