How to verify if one email exists?

Hey! So, I am building an app which requires login but, to be safe, I want to have a verification of email. When I register, i want to send an email to the email that registered to verify it. How do I do that? Is that even possible?

Hi Gonçalo,


The email is registered on the User entity so you just need to make a query to get the email of the user.

If your user is already logged in, you can apply the filter User.Id = GetUserId() (GetUserId() is a function that returns the user id logged-in).

If your user has not logged-in yet and you have just the username, for instance, your filter on the query should filter by the username.

Already have that, my question is if I can send an email to the usar email and check if it exists. Imagine I register with "test@gmail.com". I want to send an email to "register@gmail.com" so he can confirm his identity and check if the mail exists
