Okay. I have an idea that might make is simple.. So to send an email post sign up, you can do that by overriding the sign up API on the backend (see post sign up / in docs). You can do this by using the email verification functions we provide on the backend. Then on the frontend, you can override the component for email veriifcation screen to make it as per your liking. This way, you will have full control of how you want to make it behave.
