💬 Informal Letter & Email Writing — the format

Write to someone you know, sounding like a person rather than an institution.

Writing for: A friend or relative. They know you, so explaining background at length reads oddly.

Register: Informal

Length: Usually 150–300 words depending on the paper.

Audience: A friend or relative

The format, in order

  1. 1

    Greeting

    'Dear Ana' or 'Hi Ana'. For an email, a subject line first if the task implies one.

    Subject: My trip to the coast

  2. 2

    Opening

    Warm, brief, and referring to them — not a weather report.

    Thanks for your last message — I've been meaning to reply all week.

  3. 3

    Main content

    Cover every bullet in the task, but conversationally. Anecdote beats summary.

  4. 4

    Closing

    Look forward, ask a question back, or invite a reply.

  5. 5

    Sign-off

    'Love', 'Best wishes', 'See you soon' — then your first name only.

What the marks are for

Content

  • ✓Every bullet in the task addressed
  • ✓A genuine sense of a relationship between writer and reader
  • ✓Detail and anecdote rather than bare statement
  • ✓Questions or invitations that keep the exchange going

Language

  • ✓Consistently informal register — contractions are correct here
  • ✓Natural idiom used accurately
  • ✓Varied sentence openings
  • ✓Tone sustained from greeting to sign-off

What loses marks

  • ✗Slipping into formal register — 'I am writing to inform you' to a friend
  • ✗Signing off 'Yours faithfully' on an informal letter
  • ✗Missing one of the task bullets because the chatty tone took over
  • ✗Including a full postal address, which an informal email does not need
  • ✗Writing a narrative essay with a greeting attached

Phrases that work

  • Guess what happened last week…
  • You'll never believe…
  • Anyway, enough about me —
  • Let me know what you think.
  • Write back soon and tell me all about…
