How do you know for sure whether or not to use a closing? One good test is to ask yourself whether this email is more akin to an instant message/text or a business letter. If you're giving your teammate a quick update on an ongoing project, a formal closing might not be necessary; if you're throwing your hat in the ring for a promotion, it definitely is required. When all else fails, and you're still not sure, err on the side of caution and include it. You'll never go wrong by being too polite and respectful.
What this handout is about. This handout will help you write business letters required in many different situations, from applying for a job to requesting or delivering information. While the examples that are discussed specifically are the application letter and cover letter, this handout also highlights strategies for effective business writing in general.
