With e-mail as a tool, informing doesn’t automatically mean that we are communicating with our recipients. Communication occurs when our recipient reacts in accordance to our purposes and intentions. E-mail does not communicate, you communicate (or not).
All the fields in an e-mail have meaning for the recipient, from the time the message was sent, to the way in which it was signed (Too formal?... Informal?... No signed?).
Each e-mail element affects our perception of every message pertinency, which in turn reflects the level of effectiveness of our communication effort.
The sender has the responsibility of generating bidirectional written communication through the computer. It is the position where the interaction condition is created and stimulated. With e-mail, everything start at the fingers of senders.
The chances to be effective are very low if we send e-mails covered by the investiture of a corporate position. And the opposite happens when we communicate trying to nourish the legitimacy of our personal leadership, because we write with more humbleness and assertiveness.
The e-mails we send most positively affect our recipients when we write them using a perspective that is committed to excellence in customer care and service. This approach provides a more creative view to give responses (written or not) geared to help our interlocutors.
