Use ‘Yours sincerely,’ when writing to a named person. Use ‘Yours faithfully,’ when using the ‘Dear Sir/Madam’ greeting. Use the semi-formal ‘Best regards,’ or ‘Kind regards,’ if you wish the tone to be slightly less formal.

Sincerely: ‘Sincerely’ is best used as a more neutral greeting that can work across any kind of formal letter, including a cover letter or other types of business and personal letters.

Yours Respectfully: A formal and respectful closing, “Yours Respectfully” is suitable for communications with senior officials or in formal requests where you want to convey a high level of respect.

Regards: “Regards” is a universally acceptable closing, offering a touch of warmth without being overly informal. It’s suitable for most types of business communications.

Yours Truly: This type of closing is best used for someone you know well, and it’s a complimentary closing that sounds friendlier than some of the others. It can also be a good choice for introductory emails and networking, and client emails.

Yours Faithfully: ‘Yours faithfully’ are good words to end on for letters that are more formal in nature. It’s a sign off that is personable yet professional and sounds a bit different from the other greetings, so it’s more unique.
