Do I have to use the English email format?

Emails are funny things. They're definitely a 21st-century technology, but they're still governed by the conventions of the Victorian age. Yes, the time of horse-drawn transport, handwritten letters, and excessive formality.

Some people find the English language format can be, well, formal – and it is. That doesn't mean it constrains creativity or innovation. It just provides some boundaries.

The professional email format is accepted and understood across the world. So, when you're emailing people in other businesses, or other countries, it's vital that you stick to the format. This will ensure your emails are understood by everyone who receives them.

Should you always use the English-language format? Yes, if you're writing professional emails – but there are some exceptions.

Cold emails and sales emails can – and often do – use a different format. The purpose of this is to shock the reader who is expecting a standard structure.

Also, if you're emailing friends (or sending any personal emails), you can structure them however you wish.

All this talk of the English language format has probably got you wondering what it is... So let's get to that now.

The English language email format explained

We can track the structure of emails all the way back to the 19th century (and even before that).

Of course, things have changed a little bit – with things like the subject line not being a requirement in 1872. But we're still basically using the same format.

So what is it?

The English language email format has 4 parts to it. You'll need to understand what each section is and its purpose to produce professional emails.

The 4 steps are:

  1. Email subject line
  2. Email greeting
  3. Email body copy
  4. Email sign-off/next steps

We're going to work through time one by one to explain the correct format. Once you've internalized this, you can use this format for any email you want to write.

Email subject line

Every great English email starts with the subject line. Your subject line is a snapshot inside your email. It needs to be encouraging enough to get them to open the email.

The best subject lines are:

  • Short – between 5 - 7 words (ideally, but it can be longer if essential)
  • Simple and serious
  • Provide a clear description of what the email is about
  • Includes dates, references, and titles (where appropriate)
  • Includes a deadline (if there is one)
  • Provide an instruction ("Urgent", or "Please respond") if you want to

We recommend subject lines are short and clear because we receive hundreds of emails a day, which means subject lines that are unclear or confusing could be at risk of being ignored.

Short subject lines are also easier to read on mobile devices.

Lesson #1 – Keep subject lines short, simple to understand, and clear.

Email greeting

Your email greeting is your intro to the email. This is where we deviate (a little) from the Victorian age. About 20 years ago, email writers would start emails like:

  • Dear Sir/Madam
  • Dear Mr (name)
  • Dear Ms. (name)

But today, we don't. Why? Because email writing in English constantly changes, these are outdated, irrelevant, and for some people, offensive. Instead, even the most formal emails are introduced this way:

  • Hi (person's first name)
  • Hello (person's first name)
  • Dear (person's first name)

Lesson #2 You should always use the person's first name. This helps to break down barriers and establish a personal connection immediately.

Email body copy

The body copy is where you build your message up. It could be as short as a single sentence or run to pages and pages of details. There are no rules about email length (although etiquette dictates it should be as short as possible).

Typically, the email format works like this:

  • Welcome & intro – you don't dive into business, but provide a positive welcome and (if you don't know the person) introduce yourself. This can include who you are and where you work.
  • State the purpose of your email – Get to the point quickly and state why you're messaging. "I'm applying for the advertised role of (position)" is perfect.
  • Go into detail – If you need to add extra information, here is your chance. Emails aren't essays, so keep things as short as possible. Use things like bullet points to break up text and convey complex information as simply as possible.

The body copy should be brief. You can always add links to other sources or attachments to help the reader understand what your message is about.

Lesson #3 – Include all information but be brief. Professional emails quickly get to the point.

Email sign-off/next steps

Professional emails should have a purpose (f not, why are you sending it?). This could be providing emails, asking for confirmation an application has been received, or asking someone to act.

In email terms, it's known as a call-to-action (CTA). CTAs are instructions to do something and should always be at the end of your emails.

You must also check and ensure you've provided contact details and ways for people to contact you.

Your sign-off must be suitable for the situation. Some appropriate professional sign-offs include:

  • Thanks
  • Many thanks
  • Best regards
  • Kind regards
  • Look forward to hearing from you

Avoid using overly fussy and formal endings such as:

  • Yours sincerely
  • Yours faithfully

Lesson #4 – Always include a CTA and explain the purpose of your professional email and the outcome you want.
