Free Volunteer Signup Platform for Coordinators Who Run Recurring Shifts
Slot-based shift signups, automatic reminders before every shift, QR check-in at the door, and gap alerts when slots are underbooked. Free for unlimited volunteers.
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
Reminders fire automatically before every shift at the lead time you choose. Set it once at event creation; never send a manual reminder again.
Gap alerts when slots are underbooked
I'm In! flags slots that are dangerously under capacity early enough to take action — push a Slack ping, send a top-up email, post on the team Slack.
QR check-in at the event
Volunteers get a QR code with their signup confirmation. Scan at the door from any phone in the dashboard. No separate app required.
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).
- 3Turn on automatic reminders and set the lead time (24 hours, 48 hours, or whatever fits your workflow).
- 4Share the public signup link in your newsletter, group chat, or Slack.
- 5Watch the dashboard fill up. Slots that lag trigger a gap alert.
- 6On event day, scan QR codes at the door for attendance tracking.
- 7Export the attendance CSV at the end for your records.
Who uses it
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 but charges $9.99+/month for reminder emails that I'm In! includes free.
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?
Yes — gap alerts notify you when shifts are dangerously underbooked so you can recruit top-up volunteers before event day.
Can I let volunteers swap shifts?
Yes. The signup page allows volunteers to cancel their own slot, which auto-frees it for the next person on the waitlist or any new signup.
How do reminders work?
Automatic. Set the lead time once at event creation (24h, 48h, custom), and I'm In! emails every confirmed volunteer at that lead time before their shift.
Can I collect donations or fees alongside volunteer signups?
Yes. Stripe is built in. Charge a fee for some shifts (e.g., training class) while keeping others free. Only Stripe's 2.9% + $0.30 standard processing fee applies.
What does QR check-in cost?
Free, like everything else. Open the event dashboard on your phone at the door and scan attendee QR codes.
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.
Not for you if
- ·You need to recruit new volunteers from the public (try VolunteerMatch or Idealist for that recruitment stage).
- ·You need deep multi-admin role hierarchy for a 10,000+ member institution (SignUpGenius Premium fits that scale better).
- ·Your volunteer coordination is exclusively 1:1 mentoring sessions (Calendly is the right tool for 1:1 scheduling).
