I worked in IBM for a bit before Notes and it was even worse. Everyone was given terminal software that connected to some mainframe to read email. The terminal didn’t even refresh so if you wanted to see if you had gotten email you had to refresh it manually. Fortunately I was only a contractor at the time so didn’t get much email although I did get one from an employee apologizing for cheating on me, and a followup saying the message was meant for someone else lol
