Why am I getting out of space?

I received the message that I'm running out of space. Is it because of the number of submissions?

Will you warn me when it is not possible to receive answers to my forms anymore?

Monthly periods correspond to the actual months or is it a 30-day period anytime?

Submissions counter will be reset on the first day of each month.  I see you are about to hit your monthly limit.

Let us know if you need more help.

If I delete my submissions, does it open additional space for new submissions?

No, the counter won't reset even after deleting the submissions.
