- Your name should be in bold 14- or 16-point font.
- Your address and other contact information should be in normal 12-point font.
- The font of your letterhead does not need to be Arial or Times New Roman, like the rest of your letter, but it should be professional looking and easy to read. The most important thing to remember is to include up-to-date information so that you make it easy for the employer to contact you.
- You may want to include an extra line under the letterhead to create visual appeal and to separate the letterhead from the rest of the letter.
- From here on out, use 12-point Arial or Times New Roman throughout the entire letter, set your margins to one inch, and use single spacing. Be sure your font is black, and if you're printing your letter out, use standard-sized paper (8 1/2” by 11”).
Address the recipient. Be sure to refer to the recipient by his or her proper title (Mrs., Mr., Dr., etc.). If you’re not sure who the recipient is, write, “To Whom It May Concern:” or “Dear Sir or Madam”; however, it is always best to address a cover letter to a real person to make it look like you’re not sending form letters.
- You don't necessarily need to include how you became aware of the position unless it was through a mutual contact or recruiting program—in which case you should make the most of the connection.
- If you are writing a letter of interest (also known as a prospecting or inquiry letter) in which you are asking about positions that might be available, specify why you are interested in working for the employer.
- Make your qualifications jump out at the reader by researching the company to which you are applying for a job and tailoring your letter accordingly. This will also be useful if you get an interview. Some questions to keep in mind as you write are
- What is the employer's mission? What do they promote as the one thing that sets them apart from their competitors?
- What kind of customer base does the employer have? Who is their target audience?
- What is the company's history? Who founded it? How has the business evolved? What are the main highlights of the company's performance over the past few years?
Include a positive statement or question in the final paragraph that will motivate the employer to contact you. Make this closing paragraph between two and four sentences. Direct the employer to your enclosed resume and make sure you specify that you're available for an interview. Finish off by thanking the recruiter for their time and consideration, and welcome them to get in touch with you to continue the conversation.
Write an appropriate closing. It’s a good idea to thank the reader for his or her time. After that, write “Sincerely,” “Respectfully,” or “Regards,” leave several spaces, and print your name.
Add your signature. If you will be submitting your cover letter digitally, it’s a good idea to scan and add your signature, write it in with a digital writing pad, or make a digital signature stamp with appropriate software.
Make a notation of the enclosures. If you enclose something, such as a resume, with a letter, you should indicate that the letter contains enclosures by making the notation “Enclosure” or “Enclosures” at the bottom of the letter.
A cover letter, covering letter, motivation letter, motivational letter or a letter of motivation is a letter of introduction attached to, or accompanying another document such as a résumé or curriculum vitae.
Job seekers frequently send a cover letter along with their curriculum vitae or applications for employment as a way of introducing themselves to potential employers and explaining their suitability for the desired positions. Employers may look for individualized and thoughtfully written cover letters as one method of screening out applicants who are not sufficiently interested in their positions or who lack necessary basic skills. Cover letters are typically categorized according to two purposes:
- applying for a specific, advertised opening (“letter of application”)
- expressing interest in an organization when the job seeker is uncertain whether there are current openings (“letter of inquiry”) 
Students are often asked to submit a cover letter for an internship application. Such cover letter should include examples of extracurricular and academic experience. Despite this specific information, cover letters for internship should have a standard business letter format.
- The , which responds to a known job opening.
- The , which inquires about possible positions.
Résumé cover letters may also serve as marketing devices for prospective job seekers. Cover letters are used in connection with many business documents such as loan applications (mortgage loan), contract drafts and proposals, and executed documents. Cover letters may serve the purpose of trying to catch the reader's interest or persuade the reader of something, or they may simply be an inventory or summary of the documents included along with a discussion of the expected future actions the sender or recipient will take in connection with the documents.
