Question

HOW TO WRITE SALUTATION IN A INFORMAL LETTER?

Answer 1

Greetings for informal letters should similarly convey friendliness and courtesy. But because informal letters are reserved for personal correspondence between friends and family members, you have a greater degree of latitude in how you phrase your greeting. You may choose to use a more conversational tone. Some writers substitute Hello or Hi for Dear. Informal greetings end in a comma rather than a colon.
