Memos are structured similarly to an email, including: to, from, CC (copy), the subject, and the date. Like other business communications, this info will be left-justified at the top of the document.
- To recipient name(s) and possibly their titles, or an entire department or company
- From your name, possibly with title, or department
- CC (carbon copy, from the days of all-paper): who (name or department) is being kept in the loop that this memo went out but is not the audience of it
- Subject: should be clear, specific, and succinct. What is the memo about?
- Date the memo is sent, including month, day, and year
Word has templates available for memos, but many of them are more colorful and fanciful than you'd typically see used in most contexts. "Company memo," "Memo (simple design)," and "Interoffice memo" are more likely in the style of most memos. Companies may also have a specified template they'd use.
