Why are MMS text being sent to my email?

AC Question

On my Samsung Galaxy S4 running Lollipop, any picture texts are being received by my email instead of the default texting app.

I had initially turned off the auto retrieve option because of the Stagefright virus and when I turned it back on, the picture messages started going to my email instead. The texts are being sent from a Samsung Note 4 running Lollipop, and both of us are on the Verizon network.

What do I need to do to get them retrieve as texts again?
