Cover Letters are a lot like smartphone cases: They may not always be required, but it would be stupid not to have one. Cover letters allow you to demonstrate your enthusiasm and passion, which a resume often cannot convey. Cover letters, approach letters and thank-you letters can be used to show an employer, in more detail, what you can do for them and why they should hire you. They probably won’t do you any good wrapped around your iPhone, though. (Praetoria/Getty Images) 
Sometimes you have to go back to the basics, this time we are leaving the Uggs, and leggings at home. When writing your cover letter be sure to Include these basic elements: •Your name and address •Recipient’s name, job title, company, and address •Date •Greeting •3-4 paragraph body •Your salutation and name/signature (Elnur/ AP Images) 
The one size fits approach does not work here, and it rarely works almost anywhere else. You want to tailor this specifically to the job you are applying including the job title or number. Mention the name of who referred you, as this will show you have a connection to the company. If writing a thank you letter, start with a heart-felt thank you and reference the date of the interview.

You know why you would kill this job, your friends probably know it too but the recruiter doesn’t! This is your time to play Kanye West and Brag ! Show that you’ve done your research on the company and understand their needs and culture. For a thank you letter, bring up something you learned in the interview that solidified your determination to work for them. (Owen Sweeney/AP) 
This is the finale. It is your last chance to wow the employers and show them why they need to hire, you or at least interview you. In the last paragraph you need to summarize why you think you are a good fit for the company. End with a call to action – let them know that you will follow-up in a week and invite them to contact you to discuss your qualifications further. (Greeek/Getty Images)
