I received this spam text message today which shows it was sent by an email rather than a phone number. I can't figure out any way to block this email address. As you can see, the "Block Number" button is greeted out.
I found one thread about this but it was old (like 2013) and none of the solutions worked for me on Verizon with Galaxy S10.
