If RSVP chasing is the worst part of planning an event, you're not alone. Surveys of Australian hosts consistently put ‘chasing guests' above ‘budget' and ‘venue' as the biggest stressor in the final two weeks. The fix isn't more discipline — it's a single link that collects everything in one place, and a tool that politely reminds the stragglers for you.

This guide covers the three rules of modern RSVPs, what to do about the silent 20%, and how to handle the awkward edge cases — plus-ones, late additions, dietary changes and last-minute cancellations.

Most RSVP problems are friction problems. If guests have to type their name, email and dietary preferences from scratch on a desktop website, half won't bother. If they have to remember to reply to a text three weeks later, even fewer will. Personalised one-tap links solve both problems in one move.

Email invitations get lost in promotions folders. A text almost never does, which is why SMS is the highest-response channel for Australian hosts. In Availi you buy SMS credits and text each guest their own short personal link — one credit per recipient, and because every message is capped at 160 characters it's always exactly one SMS. If a number is wrong or the message can't be delivered, the credit goes back to your balance automatically.

The real advantage is attribution. Because each guest has their own link, your invitee list shows three things per person: when you sent it, when they first opened it, and how they replied — with an ‘opened x/y' counter across the whole list. Short SMS links are tracked exactly the same as full personal links, so you can filter to the people who opened but never responded and nudge only them. That's a far kinder message than a group text to everybody.

Even with the best tools, around one in five guests won't respond by the RSVP-by date. Most aren't being rude — they've seen the invitation, mentally committed, and forgotten to tap the button. The fix is a short, warm message a week before the event: ‘Just confirming you're in — I need to give final numbers to the caterer on Friday.' For older relatives, a quick phone call works better than another message.

If you still hear nothing 48 hours before the event, treat them as a polite no and move on. Don't hold catering or seating for guests who haven't confirmed — and never let unconfirmed guests stress you on the day.
