Hello,
If you are referring to knowing or editing the Contact Forms, then those are coming through the Contact Form 7 plugin. So, you can go to Dashboard > Contact > Contact Forms > there you can find the Contact Form to edit: https://ibb.co/McYrYCz
Or if you are referring to confirmation Emails or notice wrappers after the Account creation then these are handled by WooCommerce. There isn’t a direct option available for that, you can contact WooCommerce Support for that.
Lastly, if we misunderstood you then kindly please elaborate your issue more with an Image or Video along with your Site URL too so that we can better understand and assist you accordingly.
Best Regards
