When you first start writing a salutation, you may find it difficult because you often don’t know the name of the other party when writing a development letter. In fact, you can usually solve this problem in this way.
TO: Purchasing Manager/Product Manager or TO: Whom It May Concern
(1) Knowing the other party’s name
Dear Jone
Hi, Jone
Good Day Jone
(2) Not knowing the other party’s name
Dear Purchasing Manager/Product Manager
Dear Manager
Dear Director
Dear Friend
Dear Your Teams
Hi, Sir
(3) Academic
Dear Sir/Madam. This type of salutation is more formal and relatively awkward. Generally, the first two methods can be used. In general, the salutation should be friendly and close to the reader. Just follow this principle.
