Last Tuesday I had a scheduled meeting with a client.
Monday I was on vacation.
Monday the client postponed the meeting by email.
My Out-of-Office reply informed him that I did not read my emails that day.
His inbox was flooded, so he didn’t even see my autoreply.
Tuesday morning I was at his office, and he greeted me saying “So you didn’t get my email?”
It could happen to anyone, but it’s just another reason to keep your inbox empty.
