Effective Messages to Large Groups
Perhaps most important for effective messages to groups is to distinguish carefully between messages to specific members of the group and messages to the entire group. If you’re working with fifteen people, but only three can give you the information you need, send messages only to those three people. If you want everyone in the group to have a complete record of all the email messages, send a carbon copy to other group members. But send the whole group only messages that apply to the whole group.
Why do group members want to receive only the email messages that apply to them? As more people use email regularly, they discover that they receive dozens of messages every day. By sending messages only to the people in your group who need those messages, you make sure you aren’t distracting your group members from the messages they need to pay attention to.
