Writing Professional Emails: Short, Clear, Effective

How to write work emails people understand on first read, from subject lines and opening sentences to templates for approvals, updates, meetings and follow-ups.

You open an email from a colleague and after five lines you still do not know what they want. Scroll down: three attachments and a question hidden in the middle of paragraph four. In the end you reply, "So what do you need me to do?" Emails like this waste time for both writer and reader. McKinsey Global Institute's report The Social Economy (2012) estimated that interaction workers spend about 28% of the workweek managing email, so writing well gives everyone time back.

What a professional email is

A professional email is not about fancy or long language. It is an email where the reader knows within seconds what it is about, what they need to do, and by when, and can reply once without asking back.

4 core rules

1. A subject line that states the topic and action

Use tags like [Approval needed], [FYI], [Urgent] consistently so readers can prioritise from the inbox. But do not mark everything urgent.

2. Bottom line up front

Background comes after. Someone who reads only the first two lines should still understand.

3. Short and easy to read on a phone

Many people read email on their phones while commuting. Use short paragraphs and bullets for multiple points. If the content is long, summarise in the email and attach the details as a document, or book a call instead.

4. End with a clear action

When writing to several people, name who does what: "A: check the figures. B: confirm the delivery date."

Templates you will use often

Approval request

Subject: [Approval needed] topic + deadline
Body: the request in one line, 2 to 3 reasons, the impact of no or late approval, what you need and by when

Status update

Subject: [Update] project + status (on track / delayed)
Body: current status, what is done, next steps, issues or risks and the help you need

Meeting request

Subject: Meeting request: topic, 30 minutes
Body: purpose in one line, 2 to 3 proposed slots, what to prepare

Follow-up when you have no reply

"Hi A, following up on the Project X budget approval from Monday's email. If it's approved by Thursday, the team can start on schedule. Let me know if you need any more information."

A good email is one the reader answers once, and it is done.

Common mistakes

Using AI to write emails

ChatGPT or Claude can draft emails quickly. Try: "Write an email to my manager requesting approval for a 200,000 baht budget for Project X. Lead with the main point, no more than 6 lines, polite tone." Then edit it for the real context. See the basics in ChatGPT for beginners.

Caution: always check numbers, names and facts, since AI can add details that are not true, and never paste confidential company or client data into tools your company has not approved.

Where to start

  1. Open the last three emails you sent and check whether the first sentence states what you need
  2. Save the four templates above in your notes or signature
  3. Before sending, ask three questions: what is it about, what must they do, by when
  4. Set a personal follow-up rule, e.g. if there is no reply in 2 working days, send a short follow-up
