Imagine you’re working on an important project at work. You’re writing some content about space exploration for your client. Your client has promised to send you a list of approved encyclopedias or reference books that you can use for your article. However, you haven’t received it yet. Write an email asking the client to provide you with the list. Remember to follow the email etiquette you learned in this lesson: Address your recipient by name. Mention the subject of the mail in the subject line. Clearly state the purpose of your email in the first sentence. End with an appropriate complimentary close. Make sure that your language is formal and professional.
