Are you hiding behind email? Why not use the phone?You probably realise that it can take a long time to get a decision using email. This is because of the delay often in getting a  response. There is also the problem that you have no way of measuring the emotional response of the person you are sending it to. If you need a dialogue and to get real emotional feedback from the tone of the person you are speaking to, then use the phone. It is so much quicker to get a decision, it has been said that it can take a week by email and as quick as 5mins by phone!!  Also think about a potential conflict situation how it can be resolved so much more effectively by phone instead of the backwards and forwards of email.
