Although "Sincerely" is the most commonly used ending to a letter, there are other phrases to choose from to close your letter. The ending you select should be in relation to your salutation and selected based on the type of letter you are composing. Different endings are appropriate for personal letters and business letters.
"Yours Truly," "Very Truly Yours"
"Yours truly" or "Very truly yours" can be used when there is no personal connection between the recipient and the writer. This ending is often used with the salutations "Dear Sir" or "My Dear Sir."
"Regards," "Kindest Regards," "Best Regards"
"Regards," "Kindest regards," or "Best regards" can be used for informal letters.
'Respectfully," "Respectfully Yours"
"Respectfully" or "Respectfully yours" should be used for letters to persons of authority such as judges, officials, dignitaries or professors. This closing is also used for extremely formal letters.
"Love" is a common ending to an informal letter to family and friends.
