Hi @Anonymous，
If you want to get only one E-Mail after ten people fill the Form, you must save the person response number somewhere so when the number is equal to 10, send the email in flow.
For example, you could create a sharepoint list with a number type column, and then create a item to save the person response number, the Initial value is 0, the you could create the flow to update the item to add 1 to the person response number when a new response is submitted.
I have made a test on my side, you could create the Number type column as below:
And you could create the first item in the new list as below (Because the first item's id would be 1):
You could refer to screenshot below to create the flow:
The expression in the Number column in the Update item action as below:
add(body('Get_item')?['Number'],1)
The expression in the Condition as below:
@equals(add(body('Get_item')?['Number'], 1), 10)
When the response is submitted for 10 timea, the flow would send the email as below:
Best regards,
Alice
