Set enrollment limits for your course

Q: Can I remove the seat limit after setting it?

Yes. Toggle Limit the number of seats off and save. Enrollment becomes unlimited again immediately.

In this article: How to cap enrollment at a specific number of seats, customize the message students see when your course is full, and how Ruzuku notifies you as you approach capacity. All Plans

When you'd use this

Enrollment limits are useful when you're running a cohort with a fixed group size, offering a premium small-group experience, or creating scarcity for a launch. You set a maximum number of seats, and Ruzuku automatically stops accepting new signups once the course is full.

If you don't set a limit, enrollment is unlimited by default.

Set a seat limit

Open the Manage Course menu (Cmd+K on Mac, Ctrl+K on Windows).
Click Course Settings under the Actions column.
Click the Limits tab in the left sidebar.
Toggle Limit the number of seats to on.
Enter the maximum number of seats (up to 20,000).
Click Save.

Once the limit is active, Ruzuku tracks how many students have enrolled and prevents new signups when the course reaches capacity.

Tip: Free invitations bypass the seat limit. If your course is full but you need to add someone specific, you can still enroll them by sending a free invitation.

Customize the "course full" message

Below the seat limit, you'll see a rich text editor for the No seats available message. This is what prospective students see on your sales page when the course is full.

The default message is: "This course is no longer available because it is full. Please contact [your email] with any questions."

You can customize this to include a waitlist link, information about the next cohort, or a link to a different course. The editor supports text formatting and links.

You can write this message in advance — it only appears to students when the course actually reaches capacity.

Automatic notifications

Ruzuku sends you an email notification at two milestones:

80% full — a heads-up that seats are almost gone, so you can plan accordingly.
100% full — confirmation that the course has reached capacity.

Each notification fires once. If you change the seat limit, the notifications reset so you'll be notified again at the new thresholds.

Enrollment limits vs. price point limits

The seat limit on this page is a course-wide cap — it applies to total enrollment regardless of which price point a student uses.

Price points have their own separate limits (maximum purchases, available dates, expiration dates). These are configured in each price point's settings, not here. See Set limits on price points for details.

Both types of limits can work together. For example, you could set a course-wide cap of 50 seats and also limit an early-bird price point to the first 20 purchases.

Frequently Asked Questions

Do free invitations count toward the seat limit?

No. Invitations bypass the seat limit entirely. You can always add students via invitation, even when the course is full.

What happens when a student tries to enroll in a full course?

They see your custom "no seats available" message on the sales page instead of the usual enrollment options. If you haven't customized the message, Ruzuku shows a default notice that the course is full.

Can I change the seat limit after students have enrolled?

Yes. You can increase or decrease the limit at any time. If you lower it below the current enrollment count, no students are removed — but no new students can enroll until seats open up. The 80% and 100% email notifications reset when you change the limit.
