Ensured private email is not possible precisely because you have no control over how the receiver stores the data. To make matters worse, the technology itself means you essentially have to have a third party manage your email and they will be subject to subpoena.
Taking measures to increase your privacy can be good but may not really be worthwhile when it comes to email right now. e.g., you may be tempted to send encrypted with GPG, but this will do nothing if the email host can read it and the receiver forwards it / is subpoenaed. Worse, it might flag you as someone to pay particular interest to. Simply do not send anything over email that you would not want the feds or friends and family knowing.
This applies to virtually all electronic communications, in fact. You are only as secure as the least-secure party and if the feds were to go after you they would not have much trouble getting your emails. If they were particularly hardcore, they'd go after your friends/family to get the contents.
