Who I have the same questioned this topic

I would like to know how to block getting emails being texted to my phone. I figured out how to do it on here, except that it seems to only offer that option under the main account, and not for my phone number. We have a family plan, and I went to the spam center where you can block numbers and emails and websites, and under phone numbers, I could choose my number, but not for the email/website part. Does anyone know how to solve this? It's really important.
