Still receiving an email notification after encrypting form

I set the toggle switch to encrypt new forms in settings, but I continue to receive responses to my e-mail, which, unless I am mistaken, isn't secure.

Please note that the encrypt new forms setting only applies to newly created forms after you set it. It does not apply to your existing forms.

Also, every time a submission is made to one of your forms, you'll be receiving an email notification by default.

If you wish not to receive it, you can delete the notification by following this guide How-to-Delete-Notifications-Autoresponder.
