In the days before email (pardon me for the historic reference) management would sent a copy of a memo with an attachment for us to initial to show we had read it. After reading one particularly rambling and incoherent message I initialed the attachment with the note, 'I would be interested to see a copy of the English language version'.
This comment was poorly received by management.
@gdev et al.
Say what you have to in the subject line, then busy people do not have to open it.
Have you not seen those people who have three or four email account with about 100 unread emails as 'wallpaper' ? And hidden while they web-shop or word-processor.
I'm not sure Dilbert is a guide on how to use email ;)
