PTA sent data was sent. Like you sent an email or a picture to someone.
As for sending emails without showing your phone number… if you send a "message" it's using your phone number. If you add your email account to your phone, and send through that it would show your email address instead of your phone number.
Perhaps post what phone do you have? That would allows us to give you better instructions.
