Carefully proofread every email before hitting send. I cannot tell you how many emails I received from recruits specifically addressed to a rival coach expressing their interest in that rival school. A great deal of communication in the early phases of the recruiting process is going to be cut and paste on both sides, however, making a simple mistake can dehumanize the process and render the remainder of your communication less credible. It may also be helpful to send a couple of test emails to yourself first to ensure that the font or text sizes have not changed where you have cut and pasted new names.
