What if the student doesn't respond?

Add a claim deadline and a follow-up check that offers the seat to the next person if unclaimed — see Customization ideas in the guide.

Can multiple seats open at once?

The default handles one seat per trigger; loop over more candidates in the Code node to support multiple simultaneous openings.

Waitlist to Enrolled Automation

The instant a seat opens in a full course, this automation finds the longest-waiting person on that course's waitlist and emails them an enrollment invite — first come, first served, with zero manual lookups. The waitlist entry is marked notified so no one gets offered a seat twice.

Automation flow

Step 1

Seat Opened Trigger

Fires when a Course Seats row is updated.

Step 2

Is Seat Open?

Confirms the status change is to 'Open'.

Step 3

Read Waitlist

Pulls all waitlist entries for that course.

Step 4

Pick Next Candidate

Selects the earliest not-yet-notified signup.

Step 5

Send Enrollment Invite

Emails the candidate their enrollment link.

Step 6

Mark as Notified

Prevents the same student being offered twice.

How it works

1When a row in Course Seats is updated, the workflow checks if Status was set to Open.
2If so, it reads the full Waitlist and filters to that course's not-yet-notified entries, sorted by signup time.
3The earliest signup gets an enrollment invite email.
4Their waitlist row is marked Notified = Yes so they aren't offered the seat twice, and the instructor gets a Slack confirmation.
