No besos

Contrary to popular belief, in English we do NOT end personal letters with "Kisses,". The closing you use will depend on your relationship with the person you are writing to, and will range from "Love," (for family and close friends) to "Best wishes," or "All the best," (for people you know personally, but are not very close to you).

If you would like to add some kisses (and hugs), you can include "xxx ooo" ("x" for the kisses and "o" for the hugs) after your name. These are usually written like the example: three and three, but of course, you can add as many or as few as you like.

Collins Word Exchange has some nice examples of personal letters.
