How do I turn off the auto response email that survey has been submitted?

To my understanding, you are looking for a way to turn off your notifier that send you an email every time someone submits your form, is that correct?

Here's what you can do, 

First, you can delete the notifier from the Email Tools:

Second, you can create a condition so that the notifier will not be sent. This way, you don't need delete the notifier entirely. 

Here's how:

1. Make sure you have an existing Notifier when you create your condition.

2. Create a hidden field.

3. Create your condition and it should be, "If hidden field is filled, send the notifier to your@emailaddress.com"

Since the hidden field will always remain empty and not filled, it will never send the notifier to your@emailaddress.com.

You will notice that when you check the Email Tool the Notifier will have a mark saying it is conditional and that means that notifier will only be sent if the conditions are met.

I hope this helps. Let us know if you need any further assistance. Thank you.
