In order to change the redirection destination in Email Verification immediately after sign-up for each user, I am considering sending our own verification emails using Rules.
I have implemented this according to the following document.
How can I disable Verification Mail from Auth0?
Please note that the user has already signed up for self-sign-up from the Universal Login Page.
However, note that you must have the Status toggle enabled to send the verification email using Rules.
While the Status is enabled, you could consider creating the users with verify_email: false to prevent the automatic verification email from being sent and using Rules to send the verification emails.
Hoped this helps!
Please let me know if you have any further questions.
