You should start your cover letter
with a formal salutation, such as "Dear Mr. Baker" or "Dear Ms. Smith." Write the full name of the hiring manager or recruiter if you are not sure about his or her gender, marital, or professional status. Make sure to spell the name of your contact correctly to start your letter on the right foot. Use a generic greeting such as "Dear Hiring Manager" or "Dear Recruiter" if you do not have detailed contact information. Capitalize the first letter of every noun in your greeting and use either a comma or colon afterward. No matter how you choose to start your cover letter, you should avoid the antiquated line "To Whom It May Concern."
Draw your cover letter to a close with a formal sign-off such as "Sincerely" or "Best regards." Only capitalize the first word in a closing phrase. Put your name below this line. You may also include your phone number or email address on your cover letter to make it easier for a prospective employer to contact you about a position.
