The short answer would be, it's per month - Here's a snippet from our Pricing Page to better explain it:
To sum it up, there's a MONTHLY submission limit and a TOTAL submission limit.
The monthly limit depends on the plan you have chosen. For the TOTAL, the only plan that has a limit would be the FREE Plan (capped at 500). Everything else (all the paid plans) will give you unlimited Total Submission Storage for your entire account.
