determines the tone, format, and language you use.
Feature Formal Letter / Email Informal Letter

officer, Company
Tone Professional, respectful, objective Friendly, casual, personal
Language Formal vocabulary, no contractions or Conversational, contractions

[Surname]

care

■ Remember
• Use 'Yours faithfully' when you do NOT know the recipient's name (Dear

• Informal letters allow a more personal sign-off: 'With love', 'Best wishes', 'Your
friend'.
