Many managers today are being advised to use multiple channels and redundancy when communicating with their employees, and it sounds like your manager has taken this advice to heart. This is actually not a bad thing, especially in light of the fact that a far more prevalent and serious problem occurs at the opposite end of the spectrum with managers who have practically taken a vow of silence when it comes to communicating with their team.
People have different styles of learning and absorbing information. By using several different verbal and visual techniques to send essentially the same information, your manager is increasing the likelihood of having the messages he sends actually match the messages you receive. This approach typically leads to less confusion, fewer errors, better usage of time, and increased productivity.
Rather than telling your manager that you do not need this redundancy, you will probably fare far better if you look over all of his communiqués, make sure they mesh with your understanding of the project, and communicate back with him at several points during the life of the project. In fact, just to make sure that he receives your messages accurately, you too may want to try a little redundancy.
