Common Mistakes
- Using “Sincerely” with “Dear [First Name].”
Example: “Dear Sarah, Sincerely, John.” This is too formal for a first-name greeting. - Using “Yours faithfully” with a named recipient.
Example: “Dear Mr. Brown, Yours faithfully.” This rule applies only to “Dear Sir or Madam.” - Mixing American and British conventions.
Example: Using “Yours faithfully” in a US business letter where “Sincerely yours” is standard. - Adding a comma after the closing in formal letters.
Example: “Sincerely, John Smith.” The comma is standard in emails but often omitted in formal print letters. - Using the same closing for every letter.
Example: Ending a condolence letter with “Cheers.” The tone clashes badly with the content.
