How to Organise an Online RSVP Event
Step-by-step guide to organising events with online RSVPs. Learn how to collect attendance without paid platforms, reduce no-shows, and build repeating attendees.
Collecting RSVPs for your community event shouldn't require expensive platforms, complex setup, or asking guests to create accounts. This guide covers everything from setting up your RSVP link in under 2 minutes to following up with attendees — using tools actually built for online RSVPs, not generic event platforms.
Before choosing your RSVP tool, be clear about what you're actually trying to track. Different event types have different attendance patterns, and online RSVPs work best when you know exactly who's coming.
Choose between recurring or one-off events
Recurring events (weekly meetups, monthly workshops) benefit hugely from RSVP tracking because you can spot attendance patterns and send reminders. One-off events need RSVPs to manage venue capacity and send location details. Both need a trackable system — not text/email chains.
Decide on your actual capacity limit
This is critical for online RSVPs. Setting a real capacity (25, 50, 100) creates urgency and lets you manage no-shows. If your venue holds 30 people, cap RSVPs at 25-27 to account for cancellations. No-shows on online RSVP events average 15-25%, so plan accordingly.
Identify who needs to RSVP
Only people on your mailing list? Anyone with the link? Should returning guests get priority? Your answer shapes how you'll promote the RSVP link. Most online RSVP platforms let you control this, but you need to decide first.
Plan your communication timeline
How many days in advance will you open RSVPs? When will you close them? For most community events: open 10-14 days early, close 24-48 hours before the event. This gives you time to follow up with no-shows and send final reminders.
Frequently asked questions
What's the difference between using Who's In and just sharing a Google Form or Facebook Event?
Google Forms and spreadsheets don't send automatic reminders (leading to 50%+ no-shows). Facebook Events trap your data in Facebook and only reach people who see it in their feed. Who's In is built specifically for RSVP collection: automatic 48-hour reminders, capacity limits with waitlists, check-in tracking, and the ability to message all RSVPs at once. For online RSVP events, it's the only tool built for this specific job.
How do I reduce no-shows on my online RSVP events?
The single biggest factor is an automatic 48-hour reminder (cuts no-shows by 30-40%). Second: clear venue details in your RSVP description (address, parking, entry instructions). Third: follow up with regular attendees personally to confirm they're coming. Fourth: set a realistic capacity limit and close RSVPs 24 hours before. Most no-shows are people who forgot, not people who didn't want to come.
Should I charge for my online RSVP events?
Only if there's a real cost (venue rental, instructor, materials). Free events with a 'suggested donation' button work if your community is established. Paid events work if you're clear about what people get for their money. Most community RSVP events stay free — the value is in the community, not the fee. If you do charge, use Who's In's payment integration so people pay when they RSVP, not at the door.
How many days in advance should I open RSVPs?
10-14 days is ideal for weekly or monthly events. This gives people time to see your promotion multiple times and decide without feeling rushed, but it's still close enough that they remember to come. For one-off special events, open 3-4 weeks early. For annual events, open 6-8 weeks early. Don't open RSVPs more than 3 months in advance — people forget.
What should I do with my waitlist when someone cancels?
Most RSVP platforms (including Who's In) automatically notify the first person on the waitlist when a spot opens up. They usually have 24-48 hours to confirm. This is far better than manually texting people, because it's automatic and creates a sense of urgency. Some organisers with small waitlists send a personal message instead: 'A spot just opened up — interested?' This gets higher conversion.
How do I know if my RSVP capacity is set correctly?
Track your RSVP-to-attendance ratio after each event. If 40 people RSVP and 28 show up, that's a 70% ratio (good). If 60 people RSVP and 28 show up, that's a 47% ratio (you're overselling). Adjust your capacity down. The goal is 60-75% attendance rate. If you're hitting 30-40%, either your no-show rate is too high (improve reminders) or your capacity limit is too high (set it lower).
