More than a decade ago I was included in one of these. It wasn’t work related per se, but the address list included a lot of experienced, BTDT, names-on-RFCs technology folks.
Yeah, even they got stuck in the mess of replying all, unsubscribing, lecturing people about not replying to all. It was a mess, but funny given the names involved. #neverdothis #noreplytoall
A lot of advertisers are really getting into this whole Back to the Future Day thing. A number of companies are compiling emails related to the phenomenon.

What other ads have folks seen referencing Marty and his trip back?
I 
received a message on our 800 number. “This is Mark from a-website.example. Your customers are complaining to me that they are not getting my mail. And you’re blocking mail from me. Explain this to me!”
I called him back and left a message: “I think you’re confused and I probably can’t help you.”
A few minutes later, Mark returns my call.
L: Hi, this is laura.
M: Who are you? You called me, you must be from Clearwire!
L: No, I’m not with Clearwire, I’m with WttW.
M: Then why is your phone number on the Clearwire website?
L: I don’t know, but this isn’t Clearwire. The Clearwire website is redirecting to Sprint. They got bought out a while ago.
M: Redirecting to Sprint? What does that mean? Your phone number is on Clearwire’s website. You must be with Clearwire.
L: No, really, I’m not.
M: Why is your phone number on their website?
L: I don’t know. But this is not Clearwire. (I start searching the blog because I remember some post somewhere about Clearwire.)
M: Well, who are you?
L: I run a delivery consulting firm. Is it possible you found my website and the blog post that says all clearwire.net addresses are being discontinued April 15, 2015?
M: They’re gone?
L: Yes, for more than a year now.
M: Oh.

That blog post is the #1 google hit if you search for clearwire.net.
