Job seekers often ask, "do I really need to send a cover letter with my resume?" Most don’t understand the necessity in providing the added document, or spending additional time to customize a formal letter.

The rule of thumb when applying for a job is always send a cover letter along with the resume. It offers a professional touch, but most importantly, gives you a chance to introduce yourself as the ideal candidate.

But why is a cover letter so important when the resume is doing all the work?

With a cover letter, you have the perfect opportunity to discuss your reasons for changing careers, how your transferable skills will work in the new industry, or point out specific qualifications that you possess in relation to the position for which you are applying.

The basic ingredients to a cover letter include: an introduction of how you heard about the job, your strengths relevant to the position and closing the letter with asking for the interview.

Your cover letter should be short, to the point, and accompany each resume. Utilize action words, bullet points and summarize your strengths in the cover letter. Don’t make the reader think, "does this applicant have these skills?"

Know the skills that a company is seeking in an applicant in order to customize your cover letter. Look at the job requirements listed in the ad or job announcement. Do you have these skills. Describe them to the reader as your strengths in the cover letter.

Always date your letter. Address the letter exactly as you see in the ad, including job numbers or codes. Employers are looking for your ability to take instruction, so follow the instructions exactly. If the ad states a person’s name, use it in the salutation.

With a positive attitude, a tailored cover letter, and an effective resume, do what you do best and show a prospective employer why you are the best candidate for the job.
