Dear sir or madam, how do you say it in English?

Dearsier/madam is a very formal title, which can be used in very formal invitations and letters. There have been letters coming and going, so this name is generally not used. You can use the address of Mr., Mrs., Miss, Doctor, Professor, etc.

Examples are as follows:
