How can I find out if my text messages are going to someone's email account?

[AC Question]

I want to know if someone else is getting my text messages besides the person I'm sending it to

Welcome to Android Central! I'm not sure why they'd go to someone else's email account. The recipient might get it as an email as well as a text message if they have the Sync Messages option turned on in the Email app's settings. Why do you think someone else is getting them?
