Note If you use a webmail account, you should expect that your email is NOT PRIVATE. According to the ECPA , after 180 days it becomes possible to demand email from a server without a warrant, and for non-criminal matters. This means all that has to happen is a civil attorney decides they want to see your email because they might have a reason to sue you, so they write a subpoena demanding all email older than 180 days from your provider, and it is theirs.
