Do I have to upgrade if I receive the 100 free submissions per month

1. If I receive the 100 free submissions per month, and I’m close to going over, do I have to upgrade to the paid account or can I just delete the submissions that I don’t need anymore in order to make room?

The forms will be temporarily disabled once you reach the monthly submissions limit. If you would like to be able to receive more than 100 submissions per month, you will need to upgrade your account or wait for the submissions counter reset (the first of each month).
