If your form email notifications stop being delivered, you must sign into Joomla to retrieve your data. Once you are logged in, please follow these steps:

From the top navigation, select: Components > RSForm! Pro > Manage Submissions.

You will be taken to a page where you will see a list of your form data. (It will be difficult to fully view.) On the left column, where it says "filter" select the correct form in the dropdown. (Indicated with arrow.)

Select the "Export" button at the top of the page. (Indicated with red box above.) Select the data you would like to collect and the preferred format. (You may skip this step if you're unsure.) 

Click the "Export" button at the bottom of the page. Your download will begin. Use Excel to review your submissions.
