Hi! Jotform informed me that I am "almost out of monthly submission limit".

Hi,

Since you are on a free plan you have a limit of 100 monthly submissions and 500 total submission storage. If you would like to increase your account limits you can choose one of our paid plans including Bronze, Silver, and Gold. By upgrading your plan to Bronze, you can get 1,000 monthly submissions and unlimited total submission storage. 

For more information on JotForm paid plan please visit: https://www.jotform.com/pricing/

Also, you can find detailed information regarding account limits on this guide: https://www.jotform.com/help/408-Understanding-Your-Account-Usage-and-Limits
