When you’re closing a formal email, consider the main purpose of the message. In many cases, a simple expression of gratitude is an appropriate way to end the email.  For example, if your recipient has helped you or is helping you with something, try: “Thank you for your assistance with this matter.” You can also thank your recipient simply for giving you their time and attention. For example, “I appreciate your consideration,” or “Thank you for taking the time to review this issue.” In some cases, you may need to prompt your recipient to take further action or respond to you in some way. You can use the final line of your email to state or reiterate what you need from them.  For example, if you’re expecting your recipient to get back to you, say something like: “I look forward to discussing this with you further.” You can also request some other type of action. For example, “Please finish the report and send it to me at your earliest convenience.” If the recipient of the email needs something from you, then the final line of the email is a good place to address that. Assure them that you are taking the requested action or that you are planning to do so.  For example, “I will send the completed forms to you by next Friday.” You can also use the closing line as an opportunity to offer further assistance or information. For example: “Please feel free to contact me if you have any questions or concerns.” When closing your email, stick to an appropriately formal tone. Use correct grammar and formal vocabulary, and avoid slang or conversational language. For example, if you’re setting up a meeting, you might close with something like, “I look forward to meeting with you on the 14th.” Avoid chatty ending lines, such as, “Ok, see ya in a few days! :)” Before sending your email, look it over for problems, such as spelling errors, typos, grammatical mistakes, and incorrect punctuation. If possible, have someone else look at your message to see if they can spot anything you might have missed. While many email programs have built-in spell checkers, be aware that these can’t catch all spelling errors. For example, your spell checker may not correct common confusions between words that sound the same but are spelled differently and have different meanings (like “compliment” and “complement”).
End with a “thanks” if your recipient is helping you. Close with a call to action if you’re expecting a response. Let the recipient know if you plan to take action. Use formal language. Check carefully for typos and grammatical errors.
