Write a formal letter in 10 minutes

By SWInfoSystems · Updated 3 November 2026

Purpose in one line, dates and numbers, one clear request.

1. Write the purpose in one line. 2. Add dates, numbers and names — exact, never invented. 3. State exactly what you want, and by when. 4. Read it once aloud and fix long sentences. 5. Sign, keep a copy, and note the date you sent it.

Why it works this way

  • One purpose per letter.
  • Exact facts beat long explanations.

Common mistakes

  • Writing the same request in three different ways.
  • Forgetting to keep a copy.

How long should a letter be? Usually one page is enough.
