Is it always safe to open zip files?

I just received an email saying that I am going to be evicted. I am pretty sure it is bogus, since it does not address me by name and does not give the location of my property. It is signed by someone with the title of “Court representative” without referring to what court it is. There is an attached zip file which the email says provides the details of the lawsuit. I am curious to see what is in the file. Should I open it?
