Free Account Limits: Monthly submissions and total submissions storage

On the free account is says I can only have 100 submissions, with this being said, if I delete submissions to remain under the 100 submissions would that work? 

Thank you for contacting us.

We have 'submissions storage' and 'monthly submissions' limits. If you delete some entries they will be deducted from submissions storage, but they will not affect the monthly submissions value.

Monthly submissions are limited to 100 entries per month on free accounts, and total submissions are limited to 500 most recent entries. We reset the monthly submissions value on the first day of each month.

If you have any follow up questions, please let us know.

Just to make sure I understand correctly, 500 is the max correct? After the 500 I would be required to update/upgrade my account.  

Once you reach the 500 total submissions limit the system will start to replace oldest entries with the new entries, so your account will keep the 500 newest entries at a time.

You can delete some entries to clear that limit, or upgrade your account to have unlimited submissions storage.
