The characteristics that help make an informal letter friendlier and more conversational in tone are the following:
- Uses contractions.
- Uses slang and colloquial language.
- Reveals the writer's personality.
- Uses underlined words for emphasis.
- Uses expressive punctuation.
- Uses the reader's name in the body of the letter.
The other features, <em>"explains why it is time to end the letter"</em> and "<em>including an apology, explaining why the writer hasn't written in so long", </em>belong to a more formal style of writing.
