I got a pretty suspicious email a few weeks ago and flagged it. Later day that our sysadmin was like “oh hey that was legit, <vendor> has started using a new marketing firm so they look like that.” I just said “Sounds like spam to me I’m going to keep on flagging it.” and he just responded with a frown emoji. Full disclosure we’re decent work buddies and I haven’t actually gotten any more emails from that company so he may have actually filtered it lol.
There are so many people in the fediverse who are just typing words because they like to see their name on a screen.
