This updated guide explains how to write effective business memos. It covers the memo's core structure (heading, body, closing), practical tips for clarity and accessibility, guidance on when to use memos versus email or chat, and a quick checklist to ensure purpose, actions, and contacts are clear.

Why memos still matter

A business memo is a concise, internal document used to inform, request, or provide status. Though many organizations now share updates by email, chat, or collaboration platforms, the memo's purpose - clear, purposeful written communication - remains the same.

Core structure

Heading

Start with who the memo is to, who it's from, the date, and a clear subject line. If your organization uses templates or an internal tool, follow that format so recipients can scan and prioritize quickly.

Body

Lead with the purpose in the first sentence: request, decision, update, or question. Follow with only the necessary context and any actions or deadlines. Use short paragraphs and bullet lists for clarity.

Closing

End with the action steps, a point of contact, and any next steps or deadlines. If appropriate, include your name, title, and how to follow up.

Practical tips for memos that get read

  • Keep it short. Aim for one screen or one page when possible. Busy readers scan for purpose and actions.
  • Use an active voice and plain language. Say who does what and by when.
  • Format for skimming: clear subject line, headings, bullets, and bolding key dates or actions.
  • Choose readable fonts and sizes. Common choices for print or PDF include Times New Roman, Arial, or Calibri at 10-12 points; for web-native posts, system sans-serif fonts improve legibility.
  • Mind accessibility: use descriptive headings, plain language, and avoid long runs of all-caps or dense blocks of text.
  • Keep tone professional. Avoid excessive punctuation, emotive language, or sarcasm - tone can be easily misread in short documents.
  • Proofread. Check grammar, numbers, dates, and names. A quick read-aloud or a short peer review catches many errors.

When to use a memo vs email or chat

Use a memo for formal internal announcements, policy changes, detailed status reports, or when you want a persistent, well-structured record. Use email or chat for short, time-sensitive questions or quick updates. If you share a memo by email or an intranet post, treat the memo as the authoritative document and link to it.

Quick checklist

  • Subject/purpose in first sentence
  • Key actions and deadlines highlighted
  • One page or one screen if possible
  • Proofread and add contact for follow-up
Clear structure and purposeful writing make memos efficient. Treat each memo as a small, formal record: say why, say what, and say who will do what next.
