How do you end a letter without using your name?

How you end a letter will depend on what kind of a letter it is and how well you know the person. Ending a letter with the term 'Sincerely' is usually used for more formal letters, such as to a boss, or some type of official. If you know the person well, you could end it 'Cordially', 'With Warmest Regards', or if the person is a family member or significant other, you could end the letter with 'Love'.
