Signature Examples for Emailed Documents. When you are sending email cover letters, it's important to include contact information so the hiring manager can easily see how to contact you. At the very least, include your name, email address, and phone number. You can also add other, optional information, such as your street address, online portfolio, or social media accounts.
Business writing varies from the conversational style often found in email messages to the more formal, legalistic style found in contracts. A style between these two extremes is appropriate for the majority of memos, emails, and letters. Writing that is too formal can alienate readers, and an attempt to be overly casual may come across as insincere or unprofessional. In business writing, as in all writing, you must know your audience.
