Doubt regarding English Grammar.?

Let us assume it is a letter, B would start, Dear Mr/Mrs/Miss C, In an email such formality is rarely observed, and might just say something like, Hi, let me introduce myself, I am B and a friend of A, who has asked that I send you this mail. all the best urban

its simple say that they are both friends of A, like A said, that B send an a formal email to C, but then B need to CC: A in email to easily recognized by C whos B are. and start telling a story to connect the communication with them.

i would say hello and address them by their name, i would chose the name to address them by depending on age, and subject matter. as if it were a business matter more formality would be appropriate, whereas an invitation would be less so. and the younger they are a greater degree of informality would be appropriate, though that depends on an individuals personality too. then mention the mutual friend A, though the word mutual is a used less frequently these days, though it describes the situation perfectly, and say A has suggested B contacts them. i wouldn't use the word "told" as it would suggest i lacked the ability to make my own decisions, but a word like suggested would be more appropriate. and then i would say what it was i wanted to say.

hi sheetal In my opinion I don't think an email saying that you are told by someone to send an email to the recipient will be considered a formal mail or there is something more about the content of the email?
