Have you ever wanted to learn some helpful tips on how to write an informal email?

The primary distinction between formal and informal email is the tone used in writing

Professional emails use formal and polite language, while personal emails use more casual and conversational language.

This article will discover if there are any rules for composing a casual email and what those rules are.

In addition, you'll be able to find some bonus tips on improving your writing for both formal and informal email writing.

Therefore, bear with me for a little longer!

Formal VS Informal Emails

Before we go any further, I'd like to point out a few key differences between business emails and informal ones.

We use formal emails when:

  • writing for business and professional applications is required
  • having a predefined and specific format
  • It is necessary to use formal and courteous terminology.
  • sentences that are long and difficult

We use informal emails when:

  • using emails for personal communication
  • there is no set format or structure
  • sending emails to friends and family members
  • using simple and casual language
  • our sentences are short and simple

For a more casual email, it's fine to just chat about whatever is on your mind. On the other hand, when sending an official email, it's best to go straight to the point.

In addition, emails for both professional and casual purposes have some similarities. They both:

  • Use terminology that is straightforward and easy to grasp.
  • Serve an important role in facilitating productive dialogue.
  • Use the same structure every time: introduction, main body, and summary.

How to Write An Informal Email?

As we mentioned, we use informal emails for personal purposes - family, friends, or people we know well.

And, while most informal emails include a greeting, body, and closing, this is not a hard and fast rule.

Because email is so casual, you can also safely use shortened phrases and acronyms with very few to no complex sentences.

In addition, you are allowed to keep informal emails short and sweet, or include many details and pieces of information.

And, even though you are writing an informal email, some things are just bad habits, right?

Here are some things you should avoid when crafting your emails:

  • Incomplete sentences
  • Run-on sentences
  • Long, complicated sentences
  • Grammatical errors

Not only are there pitfalls to avoid, but there are also factors to take into account whenever composing an informal email. Let's check them out:

1. Write a Subject Line

A subject line is required for all emails. Casual email is simpler because the content doesn't require much thought. That is to say, you are free to use any tone-of-voice in the subject line that strikes your fancy.

2. Open With Casual Greeting

When starting your informal email, a simple "hello" or "hey" is all that's needed to kick off a friendly email conversation. For a less formal form of greeting, we don't need to worry too much about the words we choose.

And to add enthusiasm and friendliness, we can also use more exclamation points and emoticons:

  • Hey [Name],
  • Hi [Name],
  • Hey there!
  • Hi!
  • Hey!

3. Point Out The Reason for Reaching Out

Every email, whether formal or informal, should point out the reason for the email:

  • "Here is the PDF you wanted."
  • "I just want to let you know that I will not make it today."
  • "I was wondering if you have time to meet me around 5PM?"

Likewise, if you need the percipient to take some action, make sure to make that as clear as possible:

  • Can I ask what you think about my ideas/suggestions?
  • Can you let me know when you would be available to meet next week?
  • Please review the following attachments before our next meeting.
  • Can you please review the agenda for the meeting and let me know if you have any suggestions?

However, when writing a reason for reaching out, keep your reader in mind from a practical standpoint. It’s beneficial for everyone that emails are as concise as possible.

4. Wrap Up With Closing Statement

Wrapping up your informal emails is similar to the opening line — use a friendly tone to sign-off:

  • See you later,
  • Take care,
  • See you soon,
  • Thanks,
  • Happy Friday,
  • Have a good weekend!

Informal Email Template

If you are still not sure how your informal email should look like, you can try by using this template when crafting your next email.

In practice, your email can look something like this:

“Hi Tonya,

Thanks for the heads up. Let’s catch up sometime soon, I’d really like to see you. How about tomorrow at noon? Are you free?

Take care,


However, that is only some of what can help you out. AI-powered tools like TextCortex have developed several features for writing any email.

For example, if you want to write an email with TextCortex's “Bullet to email” feature, all you need is to clarify key takeaways in the form of bullets, highlight them and click on the logo

Once you choose the designated feature, the TextCortex add-on will prompt the suggestion window with several variations of the email output.

All things considered, it's safe to conclude there are no strict guidelines that one needs to follow while composing informal emails.
