I'm In! vs SignUpGenius: Free Signup with Reminders Beats Paid Reminder Tier
SignUpGenius made volunteer signups famous, but the modern alternative is free, ad-free, and includes the features SignUpGenius charges for.
Short answer
I'm In! is the better fit for volunteer coordinators, sports teams, class instructors, and community organizers under 1,000 members. SignUpGenius still wins for very large institutions (10,000+ members) that need deep admin hierarchy and have budget for an enterprise plan.
I'm In! is best for
- Volunteer coordinators running recurring shifts
- Sports teams collecting practice signups and dues
- Class instructors managing capacity and waitlists
- Community organizers with unlimited participants
- Anyone who wants automatic reminders without paying $9.99+/month
- Organizers tired of seeing third-party ads on their signup page
SignUpGenius is best for
- Large religious institutions with 10,000+ members
- School districts coordinating across many campuses
- Organizations needing deep multi-admin role hierarchy
- Teams already committed to SignUpGenius Pro paid tooling

I'm In! vs SignUpGenius — FAQ
Is I'm In! actually free, or is there a hidden tier?
I'm In! is free for unlimited events and unlimited participants with no ads. Automatic reminders, waitlists, QR check-in, and payment collection are all included free. Stripe processes payments at its standard 2.9% + $0.30 fee when you collect money — that is Stripe's fee, not a platform fee from I'm In!
Does SignUpGenius offer free automatic reminders?
No. Automatic email reminders on SignUpGenius require at least the Pro plan at $9.99/month billed annually. The free tier sends only confirmation emails.
Can I import my SignUpGenius events into I'm In!?
You can copy event details into a new I'm In! event in about a minute. There is no automated importer — SignUpGenius does not expose a public export of event metadata. Most coordinators rebuild from a template since the new event creation flow is under 30 seconds.
Will my volunteers complain about switching?
Most do not, because the I'm In! signup page has fewer clicks and no ads. Participants do not need to create an account to sign up.
What about ads on the signup page?
I'm In! shows zero ads on signup pages, period. SignUpGenius shows third-party ads on its free tier; the Pro plan removes them at $9.99+/month.

I'm In! is built mobile-first with a single-page signup that takes about 15 seconds to complete. SignUpGenius is functional on mobile but its interface predates the modern single-page-app standard.
