WhatsApp · where guests already are

WhatsApp RSVP, and reminders that do the chasing.

Guests won’t download another app — but they’ll answer WhatsApp in minutes. unio sends the invite, captures the yes, the headcount and the travel details, and reminds whoever’s gone quiet.

On numbers your guests already use — no app, no login, no new group.

Before unio

Guests won’t chase themselves. So you do.

Three hundred invitees, and the confirmations trickle in over calls, forwarded messages and a spreadsheet you update at midnight. Who’s coming? How many? Flying in when? You end up phoning families one by one — and still walk into the week not sure of the headcount.

unio moves all of that onto WhatsApp, where guests already reply, and keeps the answers where the whole plan can use them.

01

The invite asks. Guests just tap.

Send the invite over WhatsApp and guests reply with a tap — yes or no, no app to install, no link to a form. Every answer lands as a live headcount you can actually trust.

Watch it fill in real time: 84 of 120 confirmed, the rest flagged to nudge.

It collects what you’d otherwise chase

Not just yes or no. The same conversation gathers headcount, arrival and flight, whether they need a room, dietary needs and who’s coming with them.

All of it drops straight onto the guest’s card — linked to rooms, cars and functions — so the answer is never trapped in a chat thread again.

Reminders and updates, per function

Message just the sangeet guests, or everyone flying in on the 13th. Reminders go out on their own to whoever hasn’t replied, and you can see what was delivered and read.

Multi-day, multi-function weddings stay sorted — one guest list, a broadcast for each event, no thousand-person group anyone mutes.

The point of all of it

A headcount you can trust, without a single phone call.

Every yes, every flight, every diet — captured on WhatsApp and on the record, so the kitchen, the rooms and the cars all plan off the same numbers.

Questions

What planners ask about RSVP.

Do guests need an app to RSVP?

No. Guests reply right inside WhatsApp on the number they already use — no app to download, no link to a form, no account to create.

How does WhatsApp RSVP work?

unio sends the invite as a WhatsApp message with tap-to-reply options. The guest's answer becomes a live headcount, and the details land on their guest card automatically.

Can it collect travel and dietary details too?

Yes — the same conversation gathers headcount, arrival and flight, room needs, dietary preferences and companions, all linked to rooms, cars and functions.

Does it send reminders on its own?

Yes. Guests who haven't replied get scheduled reminders automatically, so you're not chasing them one by one.

Can I message just one function's guests?

Yes. Send a broadcast to any function — sangeet, haldi, wedding — from one guest list, with delivery and read counts, instead of a single group everyone mutes.

Is this official WhatsApp?

unio sends through the WhatsApp Business platform, so messages come from a verified business identity — not a personal number that risks being blocked.

Walk into the week knowing your numbers.

We're onboarding a small set of studios for the 2026 season and shaping unio around how they actually work.

We reply on WhatsApp within a day.
