What is a memo?

A memo, short for memorandum, is a brief document used within organisations to share important information, updates, or requests.

Compared to emails, memos are more formal, follow a set structure, and are often kept as part of official records. They’re typically used for announcing new policies or internal changes, or updating teams on project milestones.

A well-written memo saves time, reduces misunderstandings, and makes sure everyone is aligned. This is especially important for fast-paced or hierarchical workplaces.

Memo breakdown: What should be included?

An effective memo includes specific sections that structure its contents. This makes sure nothing important is left out.

Here are parts of a memo to include:

1. Heading: This includes the name or department to which the memo is addressed, including the job title, as well as who issued the memo. This also consists of the memo’s subject and the date it was issued. This makes it immediately clear who is involved and what the memo is about.
2. Opening statement: This states the purpose of the memo in one or two sentences.
3. Context: This provides background information or events in the lead-up to the memo.
4. Task statement: This states who needs to do a given task or action.
5. Discussion: This adds more detailed information, reasoning, and data behind the memo.
6. Closing statement: This wraps up the message and may include the next steps or a call to action.
7. Attachments (if any): These may include supporting documents relevant to the memo.

When you’re writing a memo, leave about half of the memo’s contents for the discussion. Your memo’s opening, context, and task statement should all take up about ¼ of the entire memo. Make sure to keep your header and closing concise, using about one to two lines for each part.

This structure gives you a balanced, organised format that will help readers grasp the information in your memo.

How to format your memo

Apart from a solid structure, a clean and consistent layout will make your memo easier to read. A good format will also show professionalism and attention to detail – a skill every employer appreciates.

To keep your memo professional, make sure to follow these formatting guidelines.

Font

For easy reading, you can use a 12-point font for the memo’s body and a 14- to 16-point font for headings. Make sure to use a simple, professional font such as Arial or Times New Roman.

Spacing, alignment, and margins

As a rule of thumb, use single-spaced paragraphs for your headers. Then, use double-spaced paragraphs for the body text. Instead of using indentations to move on to the next paragraph, skip a line for easier reading.

Traditionally, memos use left-justified paragraphs throughout the text. Make sure your left and right margins are even for a balanced look.

Use of lists and headings

If you’re presenting multiple points in your memo, use bullet points or numbered lists instead of blocks of text. Using lists will make your memo easier to read and will avoid overwhelming your readers.

If your memo is particularly long and covers various topics, you can use headings to break up your body text. For instance, in a memo about a paid leave policy, you could chunk your memo into sections about annual leaves, sick leaves, and emergency leaves.

Length considerations

It’s best not to overwhelm your readers with too much information. As much as possible, aim for one to two pages when writing your memo. After all, memos should be concise and straight to the point.

How to write an effective memo

If you want to write a good and effective memo, make sure your writing is clear, direct and professional. In the workplace, business writing should always be easy to read. This means breaking down big ideas and avoiding confusing phrasing.

Here’s how you can write good memos:

• Use a direct tone. Make sure to get straight to the point in the first sentence of your memo.
• Stay organised. Group related information together for a clear structure. You can also use headings or lists to make your memo easier to read.
• Keep it concise. Avoid long-winded explanations. Make sure your memo only includes what the reader needs to know.
• Be clear. Write using simple, everyday language. As much as possible, avoid technical jargon unless you’re sure your reader understands it.
• Use an active voice. An active voice makes your writing strong and confident. For instance, instead of writing, “The task was completed by the team,” write “The team completed the task.”

Common types of memos

Companies can use memos for many purposes, such as policy announcements, event notifications, personnel actions, or information requests. This means different situations will call for specific types of memos.

Here are some of the most common types of memos:

1. Informational memo: These memos are for sharing updates, like policy changes or project summaries.
2. Directive memo: These kinds of memos provide instructions or assignments, like deadlines or workflow changes.
3. Study memo: These memos present research findings or data summaries which may support internal decisions at a company.
4. Problem-solving memo: These memos are for identifying issues and proposing possible solutions.

Tips for writing effective memos

At this point, you already know what sections to include in a memo and the more technical aspects of writing clearly. But what are the other guidelines you should follow to write an effective, appropriate memo?

First, make sure you’re clear about what the purpose of the memo is. This will serve as your starting point when you write your memo.

It’s also important to know your audience and use an appropriate tone. Make sure to speak their language. If you’re speaking to higher management, you might want to keep it formal. If you’re talking to a small team where you can afford to dial down the professionalism, you can write more casually.

It’s best to time your memos well, too, when it’s likely to be read and acknowledged. For instance, don’t send your memo on Friday afternoons, when everyone is getting ready for the weekend.

Lastly, don’t forget to proofread. You don’t want to send out a memo that contains spelling mistakes or unclear sentences. If it’s appropriate, you can also use lists to break down information into bullet points for easy reading.

How to write a memo in the digital age

Today, workplaces send memos via digital channels such as email or other communication platforms. The digital age paved the way for more innovative platforms to enter the scene, as 72% of employees have become frustrated with traditional digital tools.

Some of these platforms include Pyn, which delivers memos and messages based on employee journeys. Slack is another example, where workers can send memos as messages in channels. Microsoft Teams combines video, chat, and file sharing on its platform, while Asana mixes memo-style notes with tasks.

No matter what platform you’re using, it’s critical to know how to write a memo using the right format and tone. Here are some tips:

• Use digital memo templates. Platforms like Microsoft and Canva offer ready-made templates that are easy to customise for different memos.
• Make the most of email formatting. When you’re sending a memo via email, you can use memo headers and other features in the body of an email. This maintains professionalism and keeps things easier to read.
• Clarity and brevity matter. Even when you’re sending memos online, keep paragraphs short and make sure content flows logically.
