How to write a formal letter
Writing a formal letter well is mostly about order and restraint. This guide covers what to include, what to leave out, and how to lay out a letter with the right heading, salutation, body, and sign-off. There is a tool at the end if you would rather start from a draft.
Step by step
1. Decide the single outcome you want from the message. 2. State that outcome in the first two lines. 3. Add only the context the reader needs to act. 4. Make the request or next step explicit. 5. Close briefly and politely.
Common mistakes
Burying the ask at the bottom, over-explaining the background, apologising more than once, and stacking hedges like 'just wondering if maybe'. Cut all four and the message reads more confident, not less polite.
