Responding to Emails

Are you one of those people who always responds to emails, at least letting the sender know you received it? You know, a perky "thanks!" or "Got it!" or "Will do!" Or are you one of those people who is too busy to respond unless absolutely necessary? Or maybe you figure the sender should assume you received it.

I personally prefer to receive a response most of the time so I try to remember to send one.

What about you? Check out the poll and let me know your thoughts.
