RSVP website for birthday parties

# Birthday party RSVPs,  
answered in WhatsApp.

A birthday RSVP website only works if people visit it. Eventi sends your invitation as a WhatsApp message with one-tap reply buttons - to the group that never opens email - and keeps a live headcount so you know exactly how much cake, food, and seating you need.

Free to sign up and design - no credit card required.

## Party planned in four steps.

From class list to confirmed headcount.

### 1. Add the guest list

Type in guests or import a spreadsheet - class lists work great as CSV files.

### 2. Send the invitation

Your design goes out as a real WhatsApp message with tap-to-RSVP buttons.

### 3. Watch replies come in

Yes, No, or Not sure yet - tracked per guest, live in your dashboard.

### 4. Remind the quiet ones

Automatic reminders on your schedule, skipping everyone who already answered.

## Built for the  
group-chat crowd.

Birthday guest lists - school parents, family, close friends - live in WhatsApp already. An evite in their inbox competes with spam. A message in their chat gets a tap.

##### Headcount you can shop with

Kids plus adults, counted through a quick follow-up when guests confirm - not guessed from silence.

##### One tap, no forms

Yes, No, or Not sure yet - inside the chat. A personal RSVP page covers anyone who wants to change their reply.

##### No chasing in the group chat

Reminders go privately, only to guests who haven't answered - the group stays clean.
