Free Volunteer Signup Platform for Coordinators Who Run Recurring Shifts
Free slot-based shift signups, automatic reminders, and waitlists for unlimited volunteers and events. Pro adds underbooked-slot alerts.
Why this exists
Volunteer coordinators spend more time chasing down RSVPs than running events. The old playbook — Google Sheets, group texts, manual reminder emails — burns hours every week and still leaves shifts half-empty. I'm In! is built specifically for that pain.
What you get
Slot-based shift signups
Define every shift with its own start time, end time, and capacity. Volunteers see the live signup status and pick the slot that works for them.
Automatic email reminders
Confirmed volunteers receive automatic reminders 24 hours and 1 hour before the event. Organizers can also send a manual reminder.
Pro gap alerts for underbooked slots
Pro flags slots that are under capacity early enough to recruit more volunteers.
One-link sharing
Share one public link or its QR code in a newsletter, flyer, group chat, or Slack. The QR opens the same live signup page.
Waitlists
When a popular shift fills up, additional volunteers join the waitlist. Drop-outs auto-promote the next person.
Free for unlimited volunteers
No volunteer count limit, no event count limit, no ads. The platform pays for itself by being good enough that volunteer coordinators tell their peers.
How the workflow runs
- 1Create your event at https://im-in.events/create — pick a title and date in about 10 seconds.
- 2Add shifts: each shift is a time slot with its own capacity (e.g., 5 volunteers per shift).
- 3Keep automatic 24-hour and 1-hour reminders on, or send a manual reminder from the dashboard.
- 4Share the public signup link in your newsletter, group chat, or Slack.
- 5Watch the dashboard fill up. Pro can flag slots that lag.
- 6On event day, open the live roster from the dashboard.
- 7Use Pro CSV export when you need an offline roster.
Who it fits
Volunteer coordinators at schools, animal shelters, food banks, community gardens, and faith organizations use I'm In! to manage everything from one-time fundraisers to weekly recurring shifts.
How it compares to common alternatives
SignUpGenius
Familiar to long-time coordinators, with free and paid plans whose reminder and admin features should be checked on its current pricing page.
Google Forms + Sheets
Works for tiny one-off signups; quickly becomes a part-time job once you need reminders, capacity, or waitlists.
VolunteerMatch
Good for recruiting new volunteers from the public; not built for managing the ongoing shift signups of an existing volunteer pool.
I'm In! for Volunteer Coordinators — FAQ
Is there a volunteer limit?
No. The free tier supports unlimited volunteers and unlimited events.
Can volunteers sign up without creating an account?
Yes. The signup page is one click, no account required.
Can I require certain shifts to have a minimum capacity?
Set slot capacity on Free. Pro gap alerts flag underbooked slots so you can recruit before event day.
Can volunteers change shifts?
A volunteer can cancel from the emailed manage link. Direct edit and swap are not available yet.
How do reminders work?
I'm In! emails confirmed volunteers 24 hours and 1 hour before the event when automatic reminders are enabled. Organizers can also send a manual reminder.
Can I collect donations or fees alongside volunteer signups?
Not yet. Current signups do not collect participant payments.
What does the QR code do?
It opens the public signup page, making flyers and in-person sharing faster. It is not a check-in ticket.
Can I'm In! handle a one-time 200-volunteer event?
Yes. Set the capacity, share the link, and watch signups roll in. The free tier handles 200 — or 2,000 — without an upgrade.
