Using a good Email Format can be important to your reader in how you present yourself professionally. The following information is essential for us to learn. If you're used to using email to catch up with friends, writing a formal e-mail might feel pretty foreign to you. It's not quite the same as writing a business letter, but it's definitely a huge step in that direction. Clarity, conciseness and being correct are the keys! To write a formal email, follow these guidelines.

Use a neutral （中性的） e-mail address.
Your e-mail address should be a variation of your real name, not a username or nickname. Use periods, hyphens, or underscores to secure an e-mail address

Use a short and accurate subject header.
Avoid saying too much in the subject header, but make sure it reflects the content of your email to a person unfamiliar with you. If possible, include a keyword that will make the email content easier to remember and/or search for in a crowded in-box. For example, “Meeting on March 12th” is specific enough that the email topic won’t be mistaken for anything else

Use a proper salutation （称呼语）.
Addressing the recipient by name is preferred. Use the person's title (Mr. Mrs. Ms. or Dr.) with their last name, followed by a comma or a colon. Optionally, you can precede the salutation with "Dear..." (but "Hello..." is acceptable as well). Using a last name is more formal and should be used unless you are on first-name terms with（与。。。。关系很好） the recipient. If you don't know the name of the person you're writing to (but you really should try and find one) use "Dear Sir/Madam" or "Dear Sir or Madam" followed by a colon.

Introduce yourself in the first paragraph (if necessary).
Also include why you're writing, and how you found that person's e-mail address, or the opportunity you're writing about.

Write the actual message.
Be sure to get your point across without rambling漫谈；扯淡；长篇大论; ?Try to break up the message into paragraphs by topic to make your message more logical and digestible.

Use the correct form of leave-taking.
This will depend on your level of intimacy with the recipient. Examples include: Yours sincerely,Yours cordially,Respectfully,Best wishes.

Sign with your full name.
If you have a job title, include that in the line after your name, and write the company name or website in the line after that.

Proofread your message for content.
Make sure you haven’t omitted any important details. Reading your email aloud or asking someone to proofread it is a great way to get a different perspective on what you’ve written.

Proofread your message for spelling and grammar.
If your email provider（邮件提供商） does not already provide spelling and grammar options for you, copy and paste your email into a word processor (文字处理软件), revise it if necessary, and copy and paste it back into your email.
