How to write formal emails – the essential guide

Writing formal emails may seem challenging, but it's actually simple. Why? Because there's a standard formal email format to follow. Yes, we can stip everything back into just three sections, or building blocks. Each section follows the last, flowing to create a formal email.

The three parts include:

  • Subject line
  • Body copy
  • Sign-off/next steps

The great thing about formal emails is that there's no need to try and be creative or funny. In fact, that's the opposite of what you should do. Nobody receiving a formal email expects to laugh, smile, or find it funny. (So no jokes, emojis, or images of your cat please!)

Formal emails are effective because they're simple, clear, and easily understood. This essential guide breaks down the formal email format and shows you how to build your own template.

Formal email subject line

Everything starts with a formal email subject line. The subject line of every email should conform to a few rules. Subject lines should be short, easily understood, targeted, and professional.

In fact, the fewer words you use, the better. This is because most people will check out messages on their mobile phones, and long subject lines may not display properly.

Formal email subject lines are simple and straightforward to write. If you want some inspiration, try these:

  • Thank you for your recent email
  • Greetings from (your name)
  • Introduction: (your name)
  • Please accept my resignation
  • Resignation notice: (job name)
  • Goodby on my last day

See what we mean? No personality, just 100% professional. That’s what formal messages are all about.

Formal email body copy

In the formal email body, you delve into the details and engage your audience. The great thing about formal emails (as our samples show) is how easy they are to write.

Here, we build up a formal email sample to request information from a new supplier.

Start with a polite greeting. In the past, all formal emails would begin with a "Dear Sir/Madam" or "Dear (person's name)," – but things have moved on. Today, you should start with the person's name ("Hi") or with a collective term if you're engaging a group ("Hi, colleagues").

One principle all emails should follow is, to sum up everything in the first sentence or paragraph.

So, in this formal email sample, we will request some information.

"My name is (your name). I'm contacting you from (company name) and would like to request (whatever you want to request)."

This is a basic message, but it does everything you need it to. We want to add more context, so we can include more details in our email sample.

"I'm requesting the information for my business. We are interested in learning about your products as we seek alternative suppliers."

This is great. Now explain precisely what you want. Use bullet points or lists to make it as easy as possible for suppliers to complete your requests:

"To make it as easy as possible for you to complete my request, I've listed out what I need here: (include list)."

 Learn more about how to write emails requesting something.

Formal email sign-off/next steps

At the end of the email, you'll want to wrap things up professionally – but before you do, add a deadline and set out the next steps. How? Let's show you this email sample ending.

"We've sent this request to several other suppliers and have set a deadline for responses of (insert deadline date). Please can you confirm that you have received this email and that you intend to submit a response? If you have any questions or queries or require clarification of any details, you can contact me at (insert contact info)."

We're almost at the end – but you'll need to sign off politely.

"Thank you in advance for submitting a response. We're excited at the potential of working with you."

Finally, add a sign-off (Many thanks, kind regards, etc.) and the rest of your information. Include your name, job title, contact details, and full signature.

Dos and don’ts of formal emails

Here are some dos and dont’s to help you create formal emails that get the result you want. It’s all about helping you to find your voice and deliver a message that cuts through the noise.

  • Don’t use “Dear Sir/Madam”. Do use the person’s first name.
  • Don’t wait for ages to get to the point. Do sum it up in the first sentence.
  • Don’t forget any details. Do take time crafting a message and checking you’ve included everything.
  • Don’t go off-script and ignore the format. Do follow our guide above.
  • Don’t make jokes or try and make people laugh. Do use a professional tone of voice.
  • Don’t waste time. Do keep emails as short as possible.
