A **Wait Until on List** step parks a person at the step until they're on a Planning Center list you choose. Use it to hold someone until they've joined a group, completed a form's list, or landed in any list that reflects the action you're waiting on — then continue the automation automatically once they're there. Unlike a [Wait](/automations/builder/wait), which pauses for a set amount of time, a Wait Until on List pauses for a **condition**: it waits for the person, not the clock. *** ## Setting It Up Add a **Wait Until on List** step and configure: * **List to check** — the Planning Center list the person needs to be on to continue. * **Check daily at** — the hour of day the daily membership check runs. * **Timezone** — the timezone that hour is measured in. The step's settings show a live **Next check** preview so you can see when the next daily check would happen. In the builder, Wait Until on List appears as an **orange** step with a **clipboard-check** icon. *** ## How Checking Works * **Checked immediately on arrival.** The moment a person reaches the step, we check the list. If they're **already on it**, they continue right away with **no wait**. * **Otherwise, checked once a day.** If they aren't on the list yet, we re-check once per day at the **hour** and **timezone** you picked. * **Membership is checked live.** Each check looks at Planning Center as it is *right now* — the same way an [If / Else](/automations/builder/if-else) step does — so someone joining the list during the wait is respected on the next check. * **People advance individually.** Each person continues on their own, as soon as a daily check finds them on the list. There are no branches — everyone eventually moves on to the next step (or exits, below). *** ## When Someone Joins the List As soon as a daily check finds the person on the list, they're released from the step and continue to the **next step** in the automation. Because checks happen once a day, someone who joins the list will continue at the next daily check, not the instant they join. *** ## If the Condition Is Never Met If a person still isn't on the list after **400 daily checks** — a bit over **13 months** — they **exit the automation**. This is recorded on their [step timeline](/automations/managing/monitoring#step-timeline) so you can see they left because the condition was never met. *** ## If the List Access Is Lost If the chosen list is **deleted** in Planning Center, or Flowforth **loses access** to it while people are waiting, the automation's owners are **notified by email** and the affected people's runs are marked **failed** — the same behavior as an [If / Else](/automations/builder/if-else) step that can no longer read its list. *** ## Rules * You **cannot place two Wait Until on List steps** back-to-back. (A regular [Wait](/automations/builder/wait) next to a Wait Until on List is fine.) * The [Wait](/automations/builder/wait) step's rules — like the 31-day maximum — **do not apply** to Wait Until on List. Wait Until on List steps aren't available on weekly and monthly ([scheduled](/automations/triggers/scheduled)) triggers, which send once to the whole list rather than running per person.
