Styles or forms of the arrangement of business letters

Extreme Block Style

It is the easiest and most comfortable style because all the lines are written starting at the left margin of the paper. With this style you always write in simple space; Between each paragraph two vertical spaces are left.

Block Style

This style is very similar to the extreme block. The difference is that the dateline, the farewell line, the pre-signature line and the signature line are written starting from the horizontal center of the paper.

In the same way, it is done with the farewell, the preliminary signature, the identification initials and the signature.

Presentation of the Business Letter

In business letters, it is important to keep certain basic rules so as not to make mistakes at the time of submission, which could cost the success of a business project.

  • In a commercial letter, both the paper and the envelope must have a letterhead. In this type of letter, it is common to attach the return postage.
  • The content of a business letter must be direct, objective, with clear and concise wording. The same style must be maintained both at the beginning and at the farewell.
  • Business letters will have spaces and margins to respect, similar to those used in a personal letter. However, the name of the company, the person and position must be placed on the left side of a business letter.
  • A commercial letter must present a space of three and a half centimeters before placing the date, and then the same process will be carried out as in the other correspondence.
  • Business correspondence should never be written by hand or machine. In these modern times, where information technologies handle the business landscape, it would leave much to be desired for a business letter that was not made on a computer.
