Replying All
It’s generally nice to feel included, but reply all isn’t the way to do it, particularly in a business setting. Considering that the average person receives a staggering 122 emails on a typical day, replying all when something isn’t actually must-have information is nothing short of rude. When you forward a meme or other non-essential info via reply all, you’re taking time out of the recipient’s day and potentially even stressing them out because of it.
