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 your event
From Create event, fill in the details and publish. See Creating an event for the full walkthrough.
Invite by email or SMS
On the event page, tap Invite. Paste email addresses or phone numbers, one at a time or comma-separated. Each guest gets a personal RSVP link.
Or share the link anywhere
Tap Share on the event page to copy the link. Drop it in WhatsApp, iMessage, Discord, a group SMS, anywhere. Anyone with the link can RSVP from any device.
What your guest sees
They click the link and land on the full event page: date, time, where, description, cover photo. No sign-in wall, no app install. They tap one of three RSVP buttons, type their name, and submit.
| What they see | What they enter |
|---|---|
| Full event details (date, time, location, host) | Nothing required to view |
| Three RSVP buttons: Going / Maybe / Can't make it | One tap |
| Their name field (pre-filled from your invite when possible) | First name, optional plus-one count |
| Add to calendar | One tap, .ics download |
The same link works for changing their RSVP later. Tell guests "this link is yours forever - hit it again if your plans change."
What no-account guests can and can't do
| No account | Signed up | |
|---|---|---|
| View the event page | Yes | Yes |
| RSVP (Going / Maybe / Can't) | Yes | Yes |
| Change their RSVP later | Yes | Yes |
| Get reminders (email or SMS) | Yes | Yes |
| Add to calendar | Yes | Yes |
| See other guests on the list | No | Yes |
| Comment on the event | No | Yes |
| Message the host in the app | No | Yes |
If a guest wants any of the things in the second column, signing up takes one form and connects their existing RSVP automatically. They don't lose anything.
From the host's side
No-account guests appear on your guest list with the name they typed and a small badge showing they're a guest. Reminders, broadcasts, and event updates fire to them via email/SMS the same way they do for signed-up guests. The only difference is they won't get push notifications (no app to receive them).
Sharing the link safely
Anyone with the link can RSVP, so don't paste the link of a private event into a fully public channel. For events where you want to gate who can RSVP, use Invite-only mode (see Privacy settings explained). For events where everyone you know is welcome, public sharing is fine.
If you paste an Invite-only event's link in public, anyone who opens it will see "this event is invite-only" but won't be able to RSVP. The link itself isn't a security hole - the visibility setting is what gates access.
