If people make a special effort in their written communications, they can nourish enough trust, and create a wide contextual framework so that e-mails convey the affinity necessary to be effective, as in fact occurs in many of our e-mail communications.
But for this to happen, senders must constantly cultivate trust and credibility with their interlocutors (key elements of personal marketing), and improve their writing skills so that they can compensate for the non-verbal components of interpersonal communication.
On the other hand, the quality of attention that our e-mails receive, and the attitude of our recipients when they read them are for the most part values determined by the positioning we cultivate as professionals and users of e-mail.
Our positioning (or reputation) as senders determines our capital of credibility, trust, and ability to generate positive responses to our requests, and the quality of our written messages increase or reduce that capital.
As with products, services, companies or institutions, people are more prone to respond positively to people that make them feel better through e-mail, due to satisfactory and positive experiences in the exchange of information.
What is the positioning we form of a person who sends many messages every day, or of the person who never responds?
What is our opinion of co-workers whose messages are difficult to understand, or who send lengthy messages, or always send "chain letters"?
Each e-mail affects your personal reputation...
