100 monthly submissions are for each form or per account?

In free account, 100 submissions/month are for one form only or for all forms that we create in that account? Appreciate your prompt reply!

100 monthly submissions are per account and will be shared by all the forms that you create. This means that if you have 5 forms, the sum of their submissions must not exceed 100 submissions, else the account and the forms get disabled until the beginning of the next month or until you upgrade.

You can see here more details on the plans limits.

Let us know if we can assist you further.
