Emails aren't going out on user signup

Jeremie:
You probably should be using wix-users.

When a user has logged into your site you can use wix-users.currentUser.isLoggedIn to test to see if your visitor is logged in.

If they are then you should be able to use wix-users.emailUser for example:

import wixUsers from 'wix-users';

$w.onReady(() => {
    let thisUser = wixUsers.currentUser;
    if (thisUser.isLoggedIn) {
        wixUsers.emailUser("R0q92ZI", thisUser.id);
    }
});

Now if you are using wixUsers.promptLogin() or wixUsers.login() you can perform this email action in a .then() call since both of these return promises that execute after the login completes.

Hope this helps
