E-mail is often called the “killer app” and many of us (especially me) seem to spend our entire waking lives reading, sorting, and sending e-mail messages. But, precisely because it is so ubiquitous and our use of it so second-nature, it can become the career-killer app as well.

Here, from CBS MoneyWatch, are five real-life ways ^[1] you can shoot yourself in the foot by hitting “send.”

Among them:

• Putting someone’s e-mail address into the send box to see who they are, but then forgetting to remove that person and accidentally copying them on something you don’t want them to read.
• Using BCC (blind copy) too freely: There’s always the danger someone at the other end will “reply all” and then your blind recipient will be outed.
• Sending an emotional email without counting to 100 first.
