JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
The storage limit is about the submissions that your account can keep saved, this limit is only for free accounts and you need to delete your oldest submissions to avoid getting this message, otherwise your oldest submissions will be deleted.
However, I have checked your account and I can see you have already upgraded your account so you will not be notified about it and you will not receive notices about out of storage anymore.
If you have questions, please let us know, we will be glad to help you.
