Transactional writing gets things done in the real world: a letter of complaint, an email to a teacher, a report for a committee. It is judged on whether it suits its audience and achieves its purpose clearly.
Match register to audience
Register is how formal or informal your language is. A letter to a headteacher needs formal register; a note to a cousin can be relaxed. Never mix the two.
- Formal: "I am writing to express my concern..."
- Informal: "Just wanted to let you know..."
Letter and email conventions
A formal letter opens with "Dear Sir or Madam" or a named recipient and signs off with "Yours faithfully" (unnamed) or "Yours sincerely" (named). Emails need a clear, specific subject line and a purposeful opening line.
If you begin "Dear Sir or Madam", end "Yours faithfully"; if you name them, end "Yours sincerely".
Structuring a report
A report informs and often recommends. Use a clear title, short factual paragraphs, and where helpful subheadings. Write in an objective, impersonal tone and end with recommendations.
Be clear and purposeful
Whatever the form, state your purpose early, organise the middle logically, and close by making clear what you want to happen next: a reply, a refund, a decision. Politeness and precision persuade far better than anger.
