+I have seen many people having problem with using email, especially from my classmates.
+Writing email is an important skill, and knowing how to write email properly is respecting
+the recipient.
+
+In this article I am writing about:
+
+- Structure of a good email
+- Information you should include in an email
+- What not to include in an email
+
+It also includes my email preference. If you violate too many red flags I stated here I probably won't read your mail.
+
+# Email Structure
+
+Here is a generic email structure:
+
+	[Tag] Subject
+
+	Greeting: Hi/Dear [name]/Sir/Madame/To whom it may concern,
+
+	Introduction
+
+	Elaboration
+
+	Regards
+
+	Signature
+
+## Subject
+
+Some people find it hard to come up with a good email subject.
+
+## Greeting
+
+It's not a problem for most people, though I have personally received many emails without greeting.
+An email is not a private message, and even for private message you probably should do a greeting
+before a conversation as well.
+
+Note:
+
+- Hi/Hello is informal, so you probably should avoid it if you don't know the person.
+- You could include the person's title (e.g., Dr.) if you like and the other person is comfortable, but for me personally, don't use Mr.
+- Refer to the person with their preferred name. For me, this means don't use my family name[^1]. Also, don't deadname trans people.
+
+## Introduction
+
+It is necessary to introduce yourself if you and the other person don't know each other. Start with
+
+	My name is... I am ...
+	I am writing this mail to ...
+
+If you know the person, you can just come to the reason you're writing this mail.
+
+## Regards and Signature
+
+To close an email, you should end it with:
+
+- Sincerely,
+- Regards,
+- Yours cordially,
+- Best,
+
+... followed by your name. 
+
+# Send in plain text
+# Language
+# Pronoun
+# Attachment
+
+[^1]: I would say it's the same for all other Vietnamese people. Vietnamese people currently has quite few family name,
+and most of them are "Nguyen", therefore we never refer to one another as family name. This could be different for other Asian culture,
+e.g. Chinese or Japanese people may use family name in formal situation.
