Avoid typos: Most employers stop reading a resume as soon as they find a typo. Have someone else read your cover letter to make sure you have caught all spelling and grammatical errors.
Include your contact information: Although your contact information is included on your resume, do not forget to place it in your cover letter, too. Do not make the employer have to search for a way to contact you--put your contact information where it can be seen.
