A Note About Email Business Letters. It might be tempting to leave out the closing when you're communicating by email, but don't give in to that temptation. Although no_closing emails are perfectly fine for everyday communication with your friends and teammates, they'll seem brusque – or worse, unprofessional – to people you don't know as well. You should also use a business letter closing when you're corresponding with someone professionally about an important issue, whether it's a new project or a job opportunity.
However, before using a general salutation (or leaving off a salutation), try to find out the name of the person you are contacting. If you are applying or inquiring about a job and the hiring manager’s name is not included on the job listing, you might look up the title of the employer or hiring manager on the company website. If there is a contact number, you might also call and ask an administrative assistant for the name of the hiring manager. If you are sending a different type of letter, you can still look up the person’s name on the company website, or speak to an administrative assistant or contact at the company for the name of the person you are trying to reach.
