Understood on the privacy concerns. Good point.
Agreed that the Callback URL is definitely preferable, if the consuming application has a backend (Lambda or more substantial). Thanks!
As for the technical part, I think you're better off passing a callback URL to the service so it posts to it when the user verifies the email. The callback URL could be an AWS lambda.
