Email stands for electronic mail. It is the easiest and the cheapest way of communication. It is used in formal, semi-formal as well as an informal way of expression or writing.

Every email you write has the same basic structure: Subject line, greeting, email body, and closing. But as with every written form of professional communication, there’s a right way to do it and standards that should be followed.

Subject line

The subject line could be the most important part of the email, though it’s often overlooked in favour of the email body. But if you’re cold-emailing someone, or just establishing a professional relationship, your subject line can entice people to open the message as well as set expectations about what’s enclosed. On the other hand, a poorly crafted or generic subject line (like “Hi” or “You don’t want to miss this”) can deter the reader and result in your email landing in the spam folder.

“Spend double the amount of time crafting the right subject line as you do on the [body] because if they don’t open the email, it doesn’t matter,” says Cole Schafer, founder and copy chief of Honey Copy.


In most email writing situations, you’ll want to include a quick greeting to acknowledge the reader before diving into your main message or request.

The exception: When you’re on an email chain with close colleagues, it often becomes more natural to drop the opener (as well as the closing). Though it may initially feel like a faux pas, it signals a better professional rapport.


The body of an email is the meat of your message, and it must have a clear and specific purpose, such as getting feedback on a presentation or arranging a meeting with a new client. It should also be concise. That way, people will be more inclined to read it, rather than skimming it and risking missing critical information. If you can, boil it down to a few choice sentences.

And for emails that require more length and detail, keep it as focused as you can. “Nobody wants to receive a novel. You want to keep it between three, four, or five lines of text,” says Schafer.


Just as you want to start things off on the right foot with your greeting, you also want to part well. That means writing a friendly sign-off.

Categories of Email

Suppose you want to give a birthday party. You want to invite some of your college friends, your colleagues and some of your senior in the office. Suppose you are writing an email to them to invite them. Is the email writing format the same for all persons? Can you use the same language and wordings in the different email writing format?

Emails are of three types:

      • Informal email
      • Semi-Formal email
      • Formal email

The email writing format is the same for each of the categories. Though the choice of words and language differ depending upon the type of email. One can use friendly and casual language in informal emails. The language used in formal emails should be professional, clear, and formal.

Informal Email

An email written for any friends, family members or relatives comes under this category. The use of polite, friendly and casual words along with proper greetings and closings are some of the rules of informal emails.

Suppose you have to write an email to your friend inviting him or her to your birthday party.
