Three memos, one structure
Every memo follows BLUF: bottom line up front. The first sentence carries the news or the request; context, detail and actions follow. Choose a memo type.
How long, for whom
The more senior the reader, the shorter the memo. Detail moves into attachments rather than disappearing.
The four header lines
| Line | Convention | Example |
|---|---|---|
| TO | Names and titles, or a group name. List people by seniority or alphabetically. | Elena Brooks, Operations Director |
| FROM | Your name and title. Some organisations add your initials by hand on printed memos. | Sam Ortiz, Warehouse Manager |
| DATE | Written out in full to avoid confusion between date formats. | 3 June 2026 |
| SUBJECT | Specific and short; include the action or amount if there is one. Often written “RE:”. | Request: £12,000 for warehouse shelving |
Memo or email?
A memo is a formal internal document, usually sent as an attachment or posted on the intranet, that people may need to refer back to. An email suits quick updates. Use a memo when the message is a decision or a rule.
| Send a memo for | An email is enough for |
|---|---|
| A new policy or procedure | A reminder of an existing rule |
| A change that affects many teams | A note to one person or team |
| A decision people must follow | A question or a request for opinions |
| Anything that may be checked later | Meeting times and quick updates |
Tone in memos
Memos are direct but not cold. Use “we” for decisions the organisation has made, “you” for what the reader must do, and avoid passive sentences that hide who decided.
| Instead of | Write |
|---|---|
| It has been decided that… | We have decided that… |
| Staff are required to… | Please… |
| Any queries should be directed to… | If you have questions, contact Ana Silva. |
| With immediate effect | From today |
Sending and storing it

- Paste the first paragraph into the email, with the full memo attached
- Save it where the team can find it later, such as the intranet
- Date-stamp every version if the memo is updated
- Link to it from any related policy or FAQ
