How to Write a Formal Email?

By
Letsignit

Between "Sincerely," "Best regards," and "Kind regards," your heart is torn... You're unsure about the best polite closing to use at the end of your cover letter, professional email, or administrative letter.

And rightly so! You don't address a colleague in the same way as you would address the mayor or your aunt Germaine. To avoid any faux pas, you need to adapt your introductory and closing greetings to your correspondent.

Don't worry! To help you navigate the maze of letter-writing etiquette, here is a comprehensive guide to greetings to use in emails. Thank you in advance for your attention. We hope you enjoy reading this guide.

What Is The Correct Format For A Formal Email?

Formal mail introduction

To capture your reader's attention and start your formal email on the right foot, there are a few essential steps to follow. The structure of an email should include a proper greeting, clear body of the text, and professional closing. Here are our three tips for a courteous introduction.

Greet Your Reader With An Initial Greeting

There's nothing like a well-chosen greeting to put your reader at ease and make them want to read on.

  • Start your email by greeting them with their job title. "Dear Ms.," "Hello Mr.," or "Dear Ms. and Mr.," if you do not know the gender of the recipient, will suffice. You can also add the last name if you know the person personally.
  • Be careful, however: not all contexts lend themselves to the addition of a surname. For example, if you are addressing a member of an administration, it is best to stick to the title. If, on the other hand, you have a personal or professional relationship with the recipient and want to add a little warmth to your introduction, you can use "Dear Ms. X."

It should be noted that in most cases, formal language is required, except when corresponding with close friends and family. Using informal language in business contexts can undermine your professional credibility.

Asking For News

Everyone likes to feel appreciated. For a polite and effective introduction, don't hesitate to ask for news from your recipient. This will have multiple effects: not only will they be more inclined to read your message, but they will also be more likely to respond to your email or act on your request.

If the context of the correspondence allows it and depending on how close you are to the recipient, you could add something like "How are you?" or "I hope you are well." It costs nothing and allows you to start your exchange on a pleasant note.

Tip: take advantage of a specific time of year, such as the holidays, to tailor your message. For example, in a New Year's email, you could wish the recipient a "Happy New Year."

Specify The Subject Of Your Email

Clearly and directly stating the reason for your email is essential for an effective introduction. First, this precision saves you valuable time, especially in a professional context. Second, it shows transparency and respect towards your correspondent, which puts them at ease and makes them more inclined to read your email.

In your introduction, add "I am contacting you about..." or "I am writing to you to...," followed by a brief summary of the subject of your email.

Don't forget to fill in the subject line. This short summary of your email is visible in the recipient's inbox and is essential for making a good first impression. A well-crafted subject line can determine whether people will open your email immediately.

How Do You Write A Proper Email Ending?

Formal mail ending

Just like the introduction, a well-written conclusion is crucial for a professional and courteous email. Here are three tips for ending your email on the right note, regardless of the context or the recipient.

Let Them Know You're Available

Before ending your email, remember to express your availability or openness to continuing the conversation with the recipient. This reassures them that their response is important to you and demonstrates your willingness to collaborate. In a professional context, it is also an excellent way to build trust and commitment.

You could, for example, add a phrase such as:

  • "I am available to answer any questions you may have."
  • "Please do not hesitate to contact me if you need anything."

Express Your Thanks

It is wise and highly recommended to thank your correspondent at the end of your email. By doing so, you highlight the attention they have given you and the time they have taken to read your message, which is always appreciated and seen as a sign of consideration. You also increase your chances of receiving a favorable response and strengthen your professional or personal relationships.

Add An Appropriate Closing Greeting

End your email with a well-chosen closing greeting, which will add a touch of respect and professionalism. Again, tailor your greeting to your audience.

If you are writing to someone you don't know, a simple expression such as "Sincerely" is perfect. If you already have a professional or personal relationship, opt for a warmer phrase such as best wishes.

Don't forget to sign after your closing! Depending on the specific context, you can simply add your first and last name, or set up a professional email signature in your email software. Always check the date before sending to ensure accuracy.

How Do You Write A Business Email to Express Gratitude?

business email express gratitude

Want to express your gratitude in the right way? Here are three ways to say thank you at the end of an email while maintaining a respectful tone.

Thank Someone For Their Time Or Attention

Saying "Thank you" to the person you are writing to for their time and attention is essential and helps create a positive atmosphere in your exchanges. It shows that you value their time and energy, which increases mutual respect. In doing so, you also ensure fruitful exchanges in the future!

To thank your correspondent for their acknowledgment, consider the following phrases:

  • "Thank you for your attention to this email."
  • "Thank you for taking the time to read this."
  • "Thank you very much for your prompt response."

Expressing Gratitude For An Action Or Service

Imagine that you spend an afternoon mowing your neighbor's lawn, and she closes the door in your face as a thank you. You would probably feel disappointed, disrespected, and unlikely to do her a favor again.

Well, it's the same with email exchanges! Taking the time to thank the person you are writing to for their service or support is an essential rule of courtesy.

You could use a phrase such as:

  • "Thank you very much for your help with this project."
  • "Thank you for your efficiency!"
  • "I am grateful for the service you provided."

Express Your Appreciation For Understanding Or Cooperation

In professional correspondence, for example when negotiating with a client, unexpected delays can arise. To prevent impatience and encourage your client to remain engaged, remember to thank them for their understanding!

Use one of the following phrases:

  • "Thank you for your patience."
  • "Thank you for your understanding, I will get back to you as soon as possible."
  • "Thank you for your cooperation."

You can also use these thank-you phrases in an automatic reply when you are out of the office. Here are a few examples of out-of-office messages.

Questions
Fréquentes

1

Is it possible to track the number of clicks on email signatures?

Yes, with the 'Campaigns' offer, it is possible to track the number of clicks on the email signatures of all your employees in the 'Statistics' area of the platform.

You can then access a detailed or global view of the number of clicks on the email signatures of each employee. You can use the search option to target a specific signature or a given period. Finally, you have the possibility to export all statistics to an Excel document.

If you launch campaigns with banners inserted in your email signatures, you can also access their performance via this same space.

2

Can we add links to social networks, our website, and appointment-setting applications such as Calendly?

With Letsignit, you can easily add social network icons in your collaborators' email signatures and link to your company pages. Also, our "attributes" feature allows you to manage personalized URLs for each of your collaborators such as their individual LinkedIn profile.

And that's not all: you can add links to an appointment-setting application, allow your customers to leave reviews easily, and integrate our 'Chat on Teams' widget to let anyone start a discussion via Microsoft Teams chat.

3

Can employees update their signature information themselves (number, function, etc.)?

It’s up to you! As an administrator of the Letsignit platform, you choose whether or not to grant modification rights to your employees. These permissions are managed on an attribute-by-attribute basis, which means that you can decide to allow the employee to change their phone number, but not the address of your premises, for example.

This feature applies to all attributes in your directory, including custom attributes created on Letsignit. When your employees change one or more attributes, your directory is obviously not affected.

4

Why it is important to standardize our email signatures on a large scale to ensure our identity and brand image?

It often happens that employees make their email signature their own: custom format, bad fonts, colors inconsistent with the brand standards... all of this has an impact on your brand!

A consistent visual identity is considered authentic and outperforms a perceived weak one by 20%. And, your customers are 2.4 times more likely to buy your products.

With Letsignit, take back control over your brand identity by standardizing all your email signatures. Our tool has many features that allow you to customize your signatures by department, by audience or by subsidiary. Not to mention the possibility of carrying out campaigns within your email signatures thanks to our Campaign offer.

What is the user experience like for our employees?

What is the user experience like for our employees?

  • If you opt for the Letsignit Add-in for Outlook, they will have a dedicated space in their Outlook account where they will be able to view the signatures and campaigns assigned to them.
  • If you opt for the Letsignit Desktop APP, they will be able to preview all their signatures and campaigns in this space. If they want to change their default signature to another one when sending an email, this will be done in their signature library in Outlook.

In both cases:

  • They preview their signature before sending an email and choose from signatures assigned to them.
  • Based on the permissions granted, they will also be able to modify their personal information such as their name, position, or address in these spaces.

In short, they have autonomy in their email signature, but you keep control on the field, signatures, and banners they can edit or use.

6

Can my employees have multiple signatures available to them?

With our "multi-signature" feature, your employees can benefit from multiple email signatures. No technical manipulation is required. Thanks to our Add-in for Outlook or the desktop app, they can change their email signatures as they wish with just a few clicks.

Everything has been thought of to go further in the personalization process based on the recipient of your emails.

7

Regarding “Green IT,” have you implemented measures to limit the digital footprint of email signatures?

If sending emails has an impact, non-optimized email signatures also have an impact. An unsuitable format or an image that is too heavy considerably increases the size of your signatures... and therefore, your emails.

As a responsible economic actor, we contribute to reducing our CO2 emissions and those of our customers in several ways:

  • Optimization of the weight of signatures and campaigns in emails.
  • Green features: lightening of signatures during response/transfer emails, possibility of not embedding images, implementation of lighter signatures for internal exchanges.
  • Integration of a 'Switch to Teams' widget to encourage your employees to continue their exchanges via chat, rather than email.

As we are increasingly involved in sustainability initiatives, our priority in 2023 is to develop even more green IT functionality.
