A memorandum is a short, structured internal document with a clear purpose, usually to inform, request action, or record a decision. The key is a simple format (header + message), plain language, and a direct ask so busy readers can scan it quickly.

Basic memo format

Most general workplace memos follow a simple two-part structure: header and message.

  • Header block (left aligned):
    • To:
    • From:
    • Date:
    • Subject: a specific, 6–12 word topic line (for example, “Updated Remote Work Policy for 2026”).
  • Message section:
    • Brief opening stating the purpose
    • Short body paragraphs or bullets
    • Clear closing with the next step or decision.

Many organizations also add “CC” and “Attachments” under the main header if the memo is shared widely or includes files.

Step‑by‑step: how to write one

Think of writing a memo as walking the reader from “why am I reading this?” to “what do I do now?” in a page or two.

  1. Define your purpose
    • Decide if you are:
      • Informing (new policy, schedule, update)
      • Requesting action (approval, tasks, decisions)
      • Recording a decision (meeting outcomes, policy change).
 * Write a one‑sentence purpose: “This memo explains… / This memo requests…”.
  1. Draft the header
    • Fill in To/From/Date/Subject with correct names and titles.
    • Put the main decision‑maker first on the “To” line if there are several recipients.
 * Make the subject concrete, not vague (“Quarter 2 Overtime Limit Changes” instead of “Update”).
  1. Write the opening
    • In 1–3 sentences, state:
      • Why you’re writing
      • What you want the reader to know or do
      • Any key date or deadline.
  1. Add brief context
    • In a short paragraph or bullet list, explain:
      • Background or problem
      • Key facts or constraints
      • Why the change or request is necessary.
  1. Provide details in sections
    • Use simple headings such as: Background, Current Status, Options, Recommendation, Timeline, Next Steps.
 * Keep paragraphs short; use bullets for dates, requirements, or lists of tasks.
  1. End with a clear action close
    • State exactly who does what by when, for example: “Please send your feedback by 20 January 2026.”
 * Add a contact line: “Contact [name] at [email] with questions.”
  1. Check layout and tone
    • Use a readable font (like 11–12 pt Times New Roman or Arial) and single spacing with extra space between paragraphs.
 * Keep the tone professional, direct, and respectful; avoid slang and unexplained jargon.

Example skeleton you can reuse

You can adapt this neutral template for most office situations.

MEMORANDUM To: [Name, Title]
From: [Your Name, Title]
Date: [Day Month Year]
Subject: [Specific topic in 6–12 words] This memo [explains/announces/requests] [main point in one sentence]. Background
[2–4 short sentences or a few bullets explaining what is going on and why it matters.] Details

  • [Key change or action 1]
  • [Key change or action 2]
  • [Important dates or requirements]

Next Steps

Please [specific task] by [deadline]. Contact [name] at [email/phone] if you have any questions.

This structure mirrors common guidance from university writing centers and business‑writing guides, so it will feel familiar in most workplaces.

Quick tips to make it effective

These small choices make a memo faster to read and harder to ignore.

  • Focus each paragraph on one main point.
  • Put the most important information near the top, not buried in the middle.
  • Use bullets instead of long blocks when listing changes, dates, or responsibilities.
  • Avoid emotional language; keep it neutral and fact‑based.
  • Proofread names, dates, and any numbers carefully before sending.

If you tell what kind of memo you need (for example, “policy change memo to staff” or “request for budget approval”), a more tailored sample text can be drafted around this structure using the same principles.
