icons on pet talk

Hey, what do the little envelopes to the far left mean? There are some that aren't open, some that are, some that just have the little lines over them.....I'm sorry if it's a stupid question, but, I was just curious. :)

If you scroll down to the very bottom of General, there are the icons and explanations as to what they mean.
