A business letter of introduction is typically used to introduce a person, company or product to the recipient. The letter should be polite, clear and no more than one page in length, and succinctly describe the item in question. Always type and print business letters of introduction, as handwritten letters appear unprofessional.
Start a new Word document and load a sheet of paper with your company's professional letterhead at the top. Be sure the margins on the left, right and top are set to 1", with a 1 1/2" margin at the bottom, and the document is left-justified. If you do not have a professional letterhead, type the name of your company on the top left, followed by the address, phone number, website URL or any other contact information, all single spaced. Then double space and type the date.
Double space beneath the letterhead and enter the name of the person you are contacting, followed by his title, the name of his company, and the company's address, all single spaced in a block. Always find a specific person to address your business letter of introduction, as a generic address (To Whom It May Concern) appears unprofessional.
Double space beneath the recipient's information and type the opening salutation, directly addressing the recipient. For example, "Dear Mr. [Recipient Name]."
Type the first paragraph, between two to three sentences. Directly explain why you are contacting the recipient, what person, company or product you are bringing to their attention and why.
Type the middle paragraph, between five to six sentences. This paragraph should go into more detail about the person, company or product you are introducing to the recipient, explaining any background information the recipient may need to know. Include your own personal experience with person or company in question if that is the subject of your letter. For products, explain its advantage over other, similar products, and include any information about special prices.
Type the final paragraph, between two to three sentences. Thank the recipient for her time and consideration in reading your letter of introduction, and clearly state why you believe she will benefit from learning more about the information you provided. Finish by giving her a way to easily find out more information about the person, company or product you introduced. For example, direct his attention to the item's website, or include a flyer or business card.
Double space and type a formal closing, with your typed name beneath. Print your cover letter and use a pen with black ink to sign above your typed name.
