A letter of application, also known as a cover letter, is a document sent with your resume to provide additional information on your skills and experience.
A letter of application typically provides detailed information on why are you are qualified for the job you are applying for. Effective application letters explain the reasons for your interest in the specific organization and identify your most relevant skills or experiences.
Your application letter should let the employer know what position you are applying for, why the employer should select you for an interview, and how you will follow-up.
What to Include in a Letter of Application
When writing an application letter you should include:
Subject (for an email letter)
List the job you are applying for and your name in the Subject Line of your email message, so the employer is clear as to what job you are interested in and who you are.
Greeting
Begin your letter greeting with "Dr./Mr./Ms. Last Name." If you do not know the employer's last name, simply write "Dear Hiring Manager" or leave the greeting off the letter and start with the first paragraph.
