How to Start a Busniess E-mail
Let us see some ideas on how to start a business e-mail.
"Dear Sir/Madam" is the most formal way to start an e-mail to someone whose name you don't know. If you do know the name, "Dear Mr. Brown" will probably be the most formal opening you need. When you are writing to someone for the first time, your opening sentence could be, "I am sending you this e-mail to inquire if ... " If you are replying to an e-mail, you could start with, "Thank you for your (recent) e-mail. I am sorry for the delay in replying to you, but I am pleased to inform you ... "
It's possible to be less formal but still polite. When writing to a colleague or a client who you have had a long working relationship with, you don't need to start with "Dear" because that is too distant and unnecessarily formal. You can simply start with their name: "Ms. Chang, thanks for your e-mail".
The more often you e-mail someone or the better you know them, the shorter the e-mails will become. So it's typical to start an e-mail to a colleague or contact you know well as follows: "Got your e-mail yesterday, thanks." Or "Hello Eliana, I'm glad to hear you got our order and will be able to make the delivery on time".
