When it comes to the epistolary genre, the first thing that comes to mind most people - is Tatyana's letter to Onegin, or even any of the classic examples of writing. Meanwhile, imagine handling a la "I write to you" on the monitor screen is difficult. What is an electronic etiquette and how to communicate in e-mails to avoid being branded ignorant?
When it comes to business correspondence, there is nowhere as important brevity. Your daily destination have to read dozens of letters, but because excessive florid style, presentation and confusion smearing thought you did not put up in the best light.
As, however, and spelling errors. In many institutions (and just have competent people) are not accepted to take seriously a person, allowing spelling mistakes or typos.

In ancient times, something weighty in addition to writing it was customary to send a parcel. Today there is an opportunity to "priattachit" any file to the letter. Attach (without prior approval) attachments larger than 1 MB is not accepted.
And finally, there is a rule of correspondence on the Internet, which also operates in a telephone etiquette. Conversation (conversation) always ends the one who initiated it.
