Why do SMS come through as an email and not as an sms?

[AC Question]

SMS comes through as an email and not as a sms.

I have a Galaxy S4 mini - for some reason sms's from my mother automatically goes to my e mail inbox and not as a sms. She has a very old phone that can't even send e mails.

Not sure at the moment. Someone will know later.
I sold my Samsung.
It could be in the Message app settings. Try removing your mum's email address from her Contact by editing.
Is it a Gmail address? I think I have gotten email notifications of sms in the past.
