You cant get email through the Google Play Developer API for most (practically all) users. If you look at the docs the emailAddress
The email address of the user when the subscription was purchased. Only present for purchases made with 'Subscribe with Google'.
Subscribe with Google was a very specific service that Google tried to introduce in 2018 that no one really uses anymore.
