When to Use Formal vs. Informal Letters

2. Date Placed below the address, aligned with the same margin.
3. Recipients Address Leftaligned, below the date.
4. Salutation Dear Mr./Ms. Surname, or To Whom It May Concern:
5. Subject (optional) A brief line summarising the purpose, often bolded.
6. Body Clear paragraphs: introduction, main points, conclusion.
7. Closing Formal signoff such as Yours sincerely, or Respectfully,
8. Signature Handsigned name plus typed name and title.
