Social Event Organiser's RSVP & Headcount Checklist

Lock in your date and check for competing social events

Pick a date that doesn't clash with other community events, major holidays, or peak nights out. Check local social calendars and community boards.

Secure your venue and note max capacity

Confirm the space is available and get the exact guest limit. For dinner parties, account for table space and flow. For cocktail events, assume tighter capacity than seated events.

Create your RSVP event on Who's In

Set up your event at whos-in.app/create in under 2 minutes. Add an event photo (essential for social events), clear description of the vibe, location, and your exact capacity limit — this prevents overcrowding.

Define the dress code and what attendees should know

Cocktail attire? Smart casual? BYO wine? Dietary restrictions you need upfront? Parking situation? Answer it all upfront to reduce back-and-forth messages.

Set your RSVP deadline at 72 hours before

For social events, a 72-hour cutoff gives you time to confirm final catering quantities, alert bar staff, or adjust table layouts. Anything later and people are already committed elsewhere.

Share your RSVP link across all your channels — once

Post in WhatsApp groups, email, Instagram Stories, LinkedIn, and any local community boards. Share it once and pin it. Who's In avoids duplicate messaging by centralising all RSVPs in one place.

Pin the RSVP link in your group chats

In WhatsApp, Telegram, or Slack — pin the link so it doesn't get buried. This is your single source of truth for attendance.

Brief any co-hosts or special guests

If you have a guest bartender, DJ, speaker, or co-host, confirm their involvement and share what vibe you're building. Confirm timing and any technical needs.

Place your final catering order based on current RSVPs

Check your Who's In dashboard for confirmed attendees. Order food, drinks, and ice accordingly. Most caterers need 10-14 days notice for social events.

Arrange volunteers for setup, registration, and cleanup

For larger dinner parties or cocktail events, assign 1-2 people to greet guests, 1 for check-in, 1 for photos. Brief them on the vibe and timing.

Send your first reminder via Who's In

Who's In automatically reminds everyone who's RSVP'd with your event details. Include parking info, dress code, and what to bring. No manual messaging needed.

Check your headcount and adjust catering

Log in to Who's In to see confirmed attendees. If numbers are below target, send a final push to your inner circle. Adjust catering quantities now.

Confirm final catering quantities and dietary needs

Review RSVP list for dietary requirements. Confirm alcohol quantities, glasses, ice, and any rentals (tables, chairs, linens) with venues or suppliers.

Plan your check-in process

Will you check people in via phone (Who's In shows who's arriving), a printed list, or a simple name check? For casual hangouts, keep it under 10 seconds.

Create a simple timeline for the event

Cocktails from 6-7pm, dinner at 7:15, dessert at 8:30? Share this with co-hosts and bartenders so service flows smoothly.

Send your final RSVP reminder with logistics

This is the most critical message. Send parking details, a maps link, exact start time, dress code, and what to bring. Who's In sends this automatically — it's your biggest no-show reducer.

Check for last-minute cancellations and reach out to waitlist

Review who's cancelled in Who's In. If spots opened up, immediately message waitlisted friends. For social events, fill cancellations from your backup list within 24 hours.

Confirm final headcount with your venue, caterer, and bar

Tell them your exact attendee count. Confirm table layout, bar setup, and any last-minute requests. For cocktail events, confirm glass and ice quantities.

Test all tech: speaker, music, lighting, chargers

If playing music or showing content, test your setup 2 days before. Dead batteries and connection drops always happen at the worst time.

Print a guest list or prepare name tags (optional)

For dinner parties with 20+ people, print your attendee list for quick check-in. For smaller cocktail evenings, name tags help with introductions.

Arrive 60 minutes early for cocktail parties, 90 for dinners

You need time to set music/lighting, arrange furniture, chill bottles, set up the bar, and mentally prepare. Rushed hosts show immediately.

Create a welcoming entry experience

Clear signage with your address, a warm greeter at the door, and a fast 20-second check-in sets the tone. For dinner parties, have coats ready. For cocktails, point to the bar immediately.

Capture candid photos and videos

Assign someone to take 15-20 candid shots throughout the night — not posed, just real moments. Use these to promote your next event and show attendees what they created.

Track who showed up vs. RSVP'd (note the no-shows)

As people arrive, check them off in Who's In or your list. This data tells you who's flaky and helps you predict future turnout. For recurring events, this is gold.

Collect feedback in the moment (optional)

A 30-second show of hands — "Did you meet someone new?" "Would you come to another?" — captures enthusiasm while it's high and guides your next event.

Send a thank-you message within 24 hours

Thank everyone who came. Include 2-3 of your best photos, mention a memorable moment, and preview your next event. This keeps momentum for recurring social gatherings.

Post photos on Instagram and tag your venue

Post your best 3-5 photos as a reel or carousel within 24 hours. Tag the venue, any guests or speakers. This acts as social proof for your next event.

Send a friendly message to no-shows

"We missed you at the dinner party — hope all's well. We're doing another next month, would love to see you then." Recovers 30-40% of occasional no-shows.

Review your RSVP-to-attendance conversion

Did 20 RSVP and 15 show up? 80-85% conversion is healthy for social events. Track this in Who's In over 3-4 events to spot patterns in your community.

Create your next event immediately while excitement is high

Strike while the iron is hot. Set up your next cocktail evening or dinner party on Who's In within 24 hours. Your attendees are already in the mindset to RSVP.
