Once we add a user with an email address, does the user get an automatic email with their login info?

To signup in the dashboard/mobile app, a mobile number is mandatory. If email is entered, the user will be able to login using email id as well. User doesn’t get an automatic email, they will receive it only after the admin triggers the signup invite.
They will get an SMS in their registered mobile number, with a login Link and ID as their mobile number.
