What is the purpose of a covering letter?

A cover letter is a written document commonly submitted with a job application outlining the applicant's credentials and interest in the open position. Since a cover letter is often one of only two documents sent to a potential employer, a well- or poorly-written letter can impact whether the applicant is called for an interview.

  • A cover letter is commonly submitted with a job application explaining the applicant's credentials and interest in the position.
  • A good cover letter complements the resume and explains why the candidate is the ideal person for the job.
  • Common cover letter mistakes can sink a job applicant.

Most job postings are done online and no longer require a physical application. Instead, applicants send companies a copy of their resume along with a cover letter either by email or with a hard copy through the mail. A resume offers a glimpse into the professional and academic experience of a potential employee. The cover letter, on the other hand, acts as an introduction written by the candidate to express their interest in the position and what makes them the best fit for the job.

A good cover letter complements a resume by expanding on items relevant to the job. In essence, it's a sales pitch that describes why the applicant is the best person for the position. Career experts advise job seekers to spend time customizing each cover letter for the particular position, rather than using a generic missive. Although this requires extra effort, it can be very helpful in allowing an applicant to stand out above the competition.

The cover letter provides information to the employer about who the candidate is as a professional and as a person. This includes their areas of interest, professional goals, knowledge, skills they've gained over the years, achievements, passions, and aspirations. The cover letter should be a one-page document that provides a clear and concise idea about why the candidate is the best person for the job. It should also highlight the cultural fit.

While there is no set template for a cover letter, the type of letter that you write will depend on the requirements of each individual company or employer. The information that is included in a cover letter will vary depending on the goals and purpose of your application.

  • An application cover letter is the most familiar type of cover letter. This is generally written in response to a vacancy that is posted on a company's website or a job board. In addition to answering any specific questions posted in the job ad, it may also highlight any experience or skills that are suitable for the position.
  • A referral cover letter is similar to an application letter, but it includes the name of a colleague or employee who recommended the applicant for the open position. A strong referral can help you stand out against other applicants.
  • A prospecting cover letter, also known as a letter of interest, is written by a job seeker and addressed to a company where they would like to work. However, it is not aimed at a specific role or vacancy. Instead, this type of letter inquires about open positions in general and may highlight any special skills that make the writer suitable for the company.

When employers post a job ad that requires a cover letter, they may specify certain requirements for the cover letter to address. For example, they may require applicants to answer certain questions, or to respect a certain word limit. It is important to follow these requirements, as they reflect on the applicant's ability to understand and follow directions.

If the employer does not set any expectations, a typical cover letter should be about a page or less, and may include a formal greeting, contact information, and links to the applicant's portfolio or work. It should highlight any special skills, and explain why you would be a good fit for the position. This is your chance to impress the employer: Even if your resume does not have everything an employer wants, a well-written cover letter can make the applicant stand out from the crowd.

However, it is possible to include too much information. Most employers will simply glance at the majority of their cover letters, and a long-winded essay might end up at the bottom of the pile. A few short paragraphs explaining your skills, and why you chose that specific employer, should be enough to put your best foot forward.

Writing a cover letter doesn't have to be tedious—even though it may seem like it's a chore. Here are a few simple tips you may want to consider when composing your cover letter:

  • Personalize your letter for each role. Never use a generic cover letter. This means you have to write a new one for each position. Be sure to include your strengths and skills, and explain why you’re the perfect candidate.
  • Include contact information. If the posting doesn't include the hiring manager's name, call the company, or check its website. Including this person's name gives your letter a proper greeting and also shows you have initiative. And don't forget to add your contact information, too. This is important if your resume gets separated from your cover letter.
  • Simplify your letter. Communicate clearly and concisely. Using complex words and sentences would most certainly fail to convey your intentions with the company and the person reading the letter probably won't bother with the rest of your application.
  • Be specific when needed. Don't rehash your resume, so be sure to quantify your accomplishments. For instance, expand on your marketing experience in your cover letter by saying you brought in 200 additional clients each month and increased revenue to $10,000. This can set you apart from candidates with vague personal details.
  • Proofread. After you’ve written the letter, go over it a few times to ensure there are no errors. Then ask someone else to do a once-over and recommend any changes you may need to make.

A simple, focused cover letter without any typos or grammatical errors will get you noticed by potential employers.

A perfect resume can often be sabotaged by a poorly thought-out cover letter or one that is laden with mistakes. Whether you include the letter as per required submission guidelines, or you simply want to emphasize your interest in the job, make sure you avoid making these blunders.

  • Names matter. This includes the name of the hiring manager, the company, and yes, even yours. Make sure you have the right names and the correct spelling. And don't forget to change the names if you're using the same cover letter for multiple jobs.
  • Restating your resume. Since the cover letter is used to identify your skills and explain how your previous experience is applicable to the desired position, don't restate the stuff on your resume. Remember, the cover letter should complement your resume, not just summarize it.
  • Keep your letter tight. Recruiters often go through hundreds of applications and don't have time to read through a three-page missive. The absolute maximum length for a cover letter should be one page, with a few concise paragraphs.
  • Omit unnecessary details. Stay on topic. There's no need to mention your graphic-design skills if you're applying for an accounting position. It's a good idea to leave out personal things like your IQ, recreational accomplishments, interests, and hobbies. That is unless they relate to the job or company.
  • Avoid sounding arrogant. Ensure your cover letter does not make you appear arrogant. While the cover letter is about you and your accomplishments, find a way of saying "I'm the best" without actually saying it. Avoid overusing words like "I," "me," or "my."
  • Remember that spelling counts. Typos and grammatical errors can show you didn't bother to proofread your own letter. And make sure to be consistent—don't convey a dash with "--" in one place and "—" in another.
  • Design matters: with the proliferation of publishing, design trends, and software, candidates have become creative in making their cover letter stand out from a design perspective. Make sure your cover letter projects your personality in terms of design while remaining professional. That is personal signature and branding.

According to Indeed, a leading job-seeking site, a typical cover letter should be about three or four paragraphs long and highlight any special experience or achievements that make the applicant exceptionally well-suited to the position.

A cover letter should start with a formal greeting, preferably addressed to the hiring manager. If you do not know who will be reading your cover letter, a generic "to whom it may concern" is an acceptable, albeit old-fashioned, way to address a cover letter. It is also acceptable to address the letter to a title, such as "Dear Hiring Manager," or "Dear Talent Acquisition Team."

An effective cover letter should highlight the applicant's skills, experience, and any achievements that make them a good fit for their prospective employer. It is also a good chance to mention anything that is not included in the resume: For example, if an applicant is drawn to a certain employer because they love a certain product, the cover letter is a great place to mention it. Make sure your cover letter also includes your name and contact information.

In a competitive jobs market, an effective cover letter is one way to make a job application stand out. This is a chance for an applicant to demonstrate why they think they would be a good fit. However, a poorly-written or meandering cover letter can hurt an application more than it helps.
