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.[2] 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 and/or lack the necessary basic skills.[1] 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').[3] According to studies, a good cover letter should: be specific and up-to-date, be well punctuated and spelled, and grammatically correct. It should be free of mistakes and typos,[4] use timelines to highlight chronological information, reference to the latest job positions, most closely related to the position for which one is demanding,[5][6] contain numbers (stark facts highlight one's achievements).
