“Yours sincerely” is a formal closing used primarily in British and international English. It indicates respect, professionalism, and a direct connection to the recipient. Traditionally, it is used when you know the name of the person you are addressing.
| Closing | Usage | Formality Level |
|---|---|---|
| Yours sincerely | When recipient name is known | High |
| Yours faithfully | When recipient name is unknown | High |
| Best regards | Less formal communication | Medium |
Always match your closing with your greeting. If you start with “Dear Mr. Smith,” end with “Yours sincerely.”
