I also agree that HubSpot should have this implemented. What I thought of doing is to create a Workflow that will send me a notification when the submissions reach a certain amount of number. After that I will manually turn off the form in the landing page and add a note saying we've reached the limit of attendees.
My team also needs this. Although one manual workaround for small numbers would be to have the form submissions to be emailed to you via the notification. Under form > options > Send submission email notifications to 'Email address'
This is still manual, but you could save the emails into an email folder to monitor submission numbers
I found other users voicing out this feature as well. It should be pretty helpful for event management too. Glad to see that the idea has been already submitted though!
We would also like to have this feature. It would be helpful if we could limit the same contact filling out forms twice. Now, 1 contact can subscribe to a form multiple times, which we would like to avoid for events and webinars.
I use a form for multiple training classes -- one question is what class would you like to attend (a unique contact property I created), each option from the drop down is set up with its own workflow which adds the person filling out the form that has selected that class to be added to a specific list (registrants list) for that class. Once this list reach a certain number of people -- I would like that option from the dropdown menu to be hidden.
We have clients that need this functionality critically. Also, it would be ideal for the cap on form submissions to be an acceptable workflow trigger that would switch a LP template from form to text.
This is a critical need for my organization. The majority of our events have a limited number of spots and we are desperately trying to find a workaround. This seems like it should be a basic function of capturing event registrations and I would imagine most marketing teams using HubSpot would agree with this sentiment.
I managed to implement something similar to this using the HubSpot Analytics API and modifying the embed code. It's not perfect but does the job. You can check out what I did via the link below. I recorded a video walking through the solution and also listed a few points on what to keep in mind. Like I said it's not perfect but it might help someone achieve their goals in the meantime.
