email attachments important

Well there are a lot of reasons why email attachments are important. 1 is because sometimes they can be very useful and provide crucial information. And for the second question you would like to send a blind copy email instead of a carbon copy email to someone. And you would because blind copy's don't give out personal information to people. Like if your gonna send a message to your friend and it's not actually them and then they can find out where you live. So thats why blind one's are better.
