A cover letter is a personalized document that introduces you to a potential employer and explains why you are the best fit for a specific job. Unlike a resume, which lists your experience and skills, a cover letter tells your story and connects your qualifications to the employer’s needs.

Employers use cover letters to evaluate communication skills, motivation, and cultural fit. A strong cover letter can significantly increase your chances of getting an interview, especially in competitive industries like healthcare, administration, and customer service.

For example, applicants applying for healthcare roles can review structured formats in home care resume and application examples or LPN new graduate resume samples to better understand how cover letters complement resumes.
