Start by researching the organization and explain in concise, yet brief, detail how your skills, expertise and accomplishments can benefit the employer. Indicate in the first paragraph the position you are applying for and how you learned about the position (e.g. internet, referral, etc.). At then end of the letter, thank the reader for their time and consideration.
2. Be Purposeful
Just as you would a resume, tailor each cover letter to the job in which you are applying. It is especially important to relate your skills and experience to that specific job in that specific company. An effective letter incorporates the following: company knowledge, your enthusiasm for the position and organization, and communication skills.
3. Address the Letter to a Specific Individual
Ideally, the letter should be addressed to the person who is likely to make employment decisions. If you do not know the contact person, call the human resources department and ask. If you cannot find contact's name, then use "To Whom It May Concern:".
