The no-account invite is PopIn's biggest differentiator. Your friend who deleted Instagram in 2019, your grandma, your ten-year-old cousin, they can all RSVP without signing up for anything.
How it works
Create and publish your event
See Creating an event.
Invite by email or SMS
On the event page, expand Host controls and guests and open the Guests tab. Add email addresses or phone numbers - for phones, pick the guest's country from the dropdown and type the number as you'd dial it locally. Each guest gets their own RSVP link.
Or share the link anywhere
Open the Share tab (or tap Share on the event) to copy the link or grab the QR code. Drop it in WhatsApp, iMessage, Discord, a group SMS, anywhere. Anyone with the link can RSVP from any device.
What your guest sees
They tap the link and land on the event page, date, time, where, description, cover photo. No sign-in wall, no app install. They tap Going / Maybe / Can't make it, type their name, and submit. They can add it to their calendar in one tap.
If you set the address to reveal only after RSVP (or to show the suburb only), no-account guests see exactly what your setting allows, same as account holders. See Hiding your event's address.
What no-account guests can and can't do
| No account | Signed up | |
|---|---|---|
| View the event + RSVP (incl. changing it later) | Yes | Yes |
| Get email / SMS reminders | Yes | Yes |
| Add to calendar | Yes | Yes |
| Ask the host a question | Yes | Yes |
| See the full guest list | No | Yes |
| Post and comment on the event's posts/stories | No | Yes |
| Get push notifications | No (no app) | Yes |
If a guest wants anything in the second column, signing up takes one form and connects their existing RSVP automatically, they lose nothing.
When a guest joins PopIn later
If a guest has a PopIn account on the same email their invite went to, their RSVP connects to it automatically, whether they signed up before or after the invite. Same for phone invites, once they verify that number in Settings. Opening the invite link while signed in to that account skips the guest page and goes straight to the event. If they use a different address, two ways to connect the dots:
They open their invite link while signed in
The RSVP page offers a one-tap Claim it button that adds the invite to their account and takes them to the event. Having the link is proof the invite was theirs.
Or you link them from the guest list
On a guest invite, tap Link and pick their PopIn profile. They get a notification asking "is this you?" - the invite only connects once they accept, so a guest's RSVP can never end up on the wrong account.
Either way their RSVP, plus-ones, and dietary notes carry over, and your guest list shows them as a PopIn member instead of a separate guest entry.
Sharing the link safely
Anyone with the link can RSVP, whatever the event's visibility, so treat the link like an invite and don't paste it into a fully public channel. On a Private event the link only ever opens the RSVP page - the full event (guest list, chat, photos) stays visible to confirmed members only. If a link gets somewhere it shouldn't, turn off the share link in your host tools and it stops working instantly.
