Keep a Volunteer Waitlist When All Your Shifts Are Full
Let interested people join your Proximatic event waitlist. When a job opens, offer them the hours; someone who accepts joins the same roster as your other volunteers.
A full event should still have a way to welcome people who want to help. If all you can offer is “try again later,” you may never hear from them when a cancellation does arrive.
Proximatic lets people join the event waitlist without choosing a shift. You'll find those names on the event when a place opens or you add another shift.
A useful update while the shifts are full is simple:
Thanks for wanting to help at Saturday's event. The current shifts are full. You're on our waitlist, and we'll get in touch with a specific job and time if a place opens.
Then make the next contact worth opening. If setup loses a volunteer, offer the setup shift and its hours to someone waiting. They can decide whether it works, and accepting puts them on the roster. You have a replacement drawn from people who already raised their hands, without posting a fresh appeal and hoping they see it.
The same approach works when extra demand creates useful work. Add the new shift to the event, then offer it to a waiting person. Their interest can become a real contribution as the plan grows.
Create your event with a volunteer waitlist.
