Are my submissions lost if I reached the submissions limit?

are you keeping track of my form entries until I upgrade? i.e. are they lost if I max out?

Each submissions received for every account will be counted. I see that your account has received more than 200 submissions in the current month. Please be noted that the submission limit is 100 for free accounts and hence your account is already scheduled to disable. Once the account is disabled, you cannot receive any submissions for the forms on your account. You'll need to upgrade your account in order to receive more submissions for your JotForms.

Hope this information helps!

Also, you'll not be losing any submissions that already been received on your account after the account is disabled.
