Mass invites get muted.
Bots get blocked.
Only a friend's note gets a yes.
Weddings, reunions, the gatherings that only happen once. The day is only as good as who actually walks in -- and broadcasts don't fill rooms. Paper Planes splits your guest list across fifty of your people: twenty names each, a personal-sounding draft they make their own, all from their own number. No bots, no blasts, no shame spirals. Just the only kind of invite that works, sent at scale.

Section I · Why bots can't fill a room
Big days don't die from lack of love. They die in mass mailers.
Stat 01✦
6%
of bulk event mailers ever get opened.
A blast from events@example.org goes straight to Promotions. Anything that smells like a bot gets ignored -- including the gathering you spent six months planning.
Stat 02✦
~70
new chats and WhatsApp shuts you down.
One organiser cannot personally invite a thousand people from one number. The platform was built to punish exactly that. Distribute the work, or the work doesn't happen.

reply rate when a friend asks vs. an organiser does.
"Hey, it’s Priya — long time. The wedding’s in May, you have to come." outperforms anything a CRM can write. Whether it’s a sangeet, a save-the-date, or a reunion RSVP — personal invites are the only invites that convert. Paper Planes just lets you scale them.
Section I·b · The math of a thousand invites
One sender hits a wall. Fifty senders fill a room.
WhatsApp punishes one phone for messaging a thousand strangers. It rewards a thousand phones for messaging one friend each. Whether you're inviting a batch or a baraat, Paper Planes turns the second case into the default -- and watches recipients quietly promote themselves into senders.
Section II · How a paper plane gets folded
Three steps. No CSVs. No copy-paste.

You tap "Send on WhatsApp."
A pre-written, personal-sounding message opens with the right number and the right context -- your batch reunion, your cousin’s wedding, your mum’s 60th. Change a word, hit send. The hard work -- the writing, the deduping -- is already done.
- Mark③paperplanes9:41Tony ThampanMarking sent…Bhanu ReddyPGP '11 · HyderabadToday · You04→05
You mark it sent.
One tap. The card slides away, the next one slides in. Your sent count climbs. The Google Sheet updates itself. Quietly, somewhere, a host stops worrying.
Section II·b · The host's-eye view
From a guest list to a full room.
What a sender sees in three taps, a host sees as a five-step pipeline. One spreadsheet at the top, one full room at the bottom, and the work of a hundred WhatsApps in between -- all of it tracked, deduped, and quietly humming along on its own.

Section III · What's in the envelope
Six small features. All in service of one job.
Smart batching
Twenty contacts at a time, prioritised so the never-contacted come first. Nobody steps on anybody's toes -- no two senders get the same aunty.
WhatsApp deep links
One tap opens the right chat with a personal-sounding draft. SMS fallback for everyone who isn't.
Live dashboard
Personal sent count, team RSVPs, set-by-set heatmap. Senders see the scoreboard climb.
Leaderboard
Light-touch competition. The honour roll updates as it happens -- without nagging the slow ones.
Two-way Sheets sync
Push every 30s, pull every 2 minutes. Your existing Google Sheet stays the source of truth.
Host portal
Sender roster, recent activity, daily targets. The host -- bride, groom, batch lead -- keeps a steady pulse.

Built for IIMB Alumni Hyderabad's Anusmaran 2026 -- but the shape fits any day that lives or dies by who shows up. Weddings, reunions, milestone parties, fundraisers.

Anusmaran 2026.
A banquet hall, full.
On the 25th of April, 2026, the IIMB Alumni Hyderabad chapter held their annual reunion at Glass Onion, Gachibowli. The list was 1,049 names long; the room sat 125. Paper Planes is what stood between the two. This page exists, in part, to remember how it felt the morning after.
Anusmaran was a reunion. The mechanics are the same for a 600-person wedding or a 100-cousin sangeet. The only thing that changes is who's at the door.

No bots. No blasts. Just fifty friends.
Stop sending blasts nobody opens. Send fifty messages people answer.
Every invite goes out from a real friend's number, in their own words. That's the only kind that gets a reply -- whether it's a save-the-date, an RSVP nudge, or a "you have to come back for this one." Paper Planes just makes it possible to send a thousand of them.
