What is a formal email?

A formal email is a type of email used for professional communication or official purposes. It is typically employed in communication between colleagues, clients, or superiors within a business or professional setting. Formal emails are characterized by their professional tone, language, and format, which are designed to convey respect, courtesy, and expertise.

Components of an Email Format

1. Email Subject Line

An email subject line informs the recipient about the specific contents of an email. It is the single, most important thing in email writing because someone opens a mail or not, depending on it. Moreover, a good, crisp, clear, and to-the-point subject line is a priority email component. Hence, it will compel and coerce the recipient to read it. A subject line depends on the content and purpose of the sender.

email format
  • The subject line in a formal email should be short. Ideally, it is supposed to be six words or one line at the most.
  • Engaging and Informative words are kept at the beginning of the subject line.
  • The subject line has to be direct and straightforward to the point.

Some examples of perfectly written subject lines –

2. Salutations

Salutation in an email format is a means to greet someone before starting to talk about the main subject. Besides, it varies from person to person, depending on the relationship one has with the recipient. Various options are available depending on the individual’s level of formality with the receiver. Therefore, it may begin with a simple ‘Hi’ preceding the name, or a more formal one like ‘Dear Madam/Sir’, ‘Dr. XYZ’ or ‘Professor XYZ.’

  • Salutations should always be respectful. Also, it should never be skipped or omitted while writing an email.
  • Avoid using nicknames, first names, or only surnames in a salutation.
  • Use a colon instead of a comma after the salutation in an extremely formal setting.
  • When the sender is unfamiliar with the recipient’s name, salutations like ‘To Whom It May Concern’ or simply ‘Dear Madam/Sir’ must be used.

3. Email Body

The body states what the email is talking about. Here, the sender crafts all the points or information they want to present to the recipient. Hence, it is a vital part of an email format. When writing an email to a stranger, a brief introduction must be provided in the body to get to the main topic immediately. The body in a format states the purpose of the sender. Moreover, the body should be short and simple without extra, ambiguous information. An email is not the place to have lengthy, continuous conversations.

Structuring the email body like a cover letter can be beneficial when applying for jobs. This includes using formal language, personalizing the salutation, and showcasing relevant qualifications to stand out to hiring managers.

  • It is a good habit to use a standard font size and style in the format. Also, before sending the email, the sender should do final proofreading, spell check, and grammar check.
  • Avoid using any cliched terms and repetition of words in the email format.
  • A positive approach and tone should be maintained throughout the body, even when rejecting any job offer or salary hike request.
  • One email should contain only one topic. Suppose a sender wants to discuss two issues with the same recipient. Then, write two separate emails stating the subject. As a result, this makes it convenient for the recipient to understand and reply efficiently on two different topics.
  • Discuss the importance of maintaining a formal tone, avoiding slang, and using an active voice.
  • Emphasize the need for clear, concise sentences and for avoiding unnecessary jargon.
  • I recommend using short paragraphs and bullet points for better readability.

4. Email Tone

The tone of your email can determine how the recipient will interpret your message. A negative or aggressive tone can create a hostile environment and make the recipient defensive, whereas a positive and friendly tone can make the recipient feel valued and appreciated. Your tone can also help to establish a professional relationship with the recipient, especially if you’re communicating with them for the first time.

In contrast, informal email writing is more relaxed and used for personal correspondence, lacking the strict rules of formal email writing.

5. Email Closing

Email closing is a crucial component of the email format. Here, the sender has to end his email respectfully after stating the matter earlier in the body. Also, the email closing tells the recipient what’s next. It includes a final call to action, wishing them luck and success or wanting a favor regarding something. Any of these have to be stated respectfully and formally. Similarly, the best way is to get cordial at the end and provide a brief salutation to finish. Another way to form an email closing can be to end on a friendly note, showing one wants to keep in touch with the recipient.

  • The email closing should support the email format and the nature of the content.
  • If the email is long, reiterate the primary concern, request, or issue to emphasize.

6. Formatting Best Practices

Font Selection:

  • Use standard fonts like Arial or Times New Roman at a readable size (e.g., 12pt).

Alignment and Spacing:

  • Recommend left-aligned text with appropriate spacing between paragraphs.

Use of Lists:

  • Encourage the use of bullet points or numbered lists to organize information.

6. Show Gratitude

It’s important to show gratitude in your emails, especially when someone has done something for you or has provided you with information. Adding a simple “thank you” to your message can make the recipient feel appreciated and valued, helping to build a positive relationship between you and the recipient. Incorporating a thank you message in your email signature is also a good practice to show appreciation.

  • Keep your thank you message concise and sincere. Avoid using generic or impersonal phrases.
  • If possible, mention the specific reason for your thank you message. This can help to show the recipient that you value their contribution.

7. Handling Attachments and Follow-Ups

Attachments:

  • Provide guidelines on naming files appropriately and mentioning attachments within the email body.

Follow-Up Emails:

  • Offer advice on when and how to send follow-up emails if no response is received.

7. Mention a Call to Action

A call-to-action (CTA) is a statement encouraging the recipient to take a specific action, such as replying to your email or clicking a link. Including a clear CTA in your email can help ensure that the recipient understands what you want them to do and prevent any confusion or misunderstandings. Make sure your CTA is clear and concise, and it’s always good to follow up after sending an email with a CTA.

  • Keep your CTA clear and concise. Avoid using vague or ambiguous language.
  • Use action-oriented language to encourage the recipient to take action. For instance, instead of saying, “Let me know if you’re interested,” say, “Please reply to this email with your availability.”
  • If you don’t receive a response after sending an email with a CTA, follow up. This can help ensure that the recipient didn’t miss your CTA or forget to respond.

8. Signature

An email format ends with the last component called a signature. These are the final words to denote the recipient, along with your name and credentials. A well-formed signature is sure to leave an impression on the reader.

Signatures should be simple words conveying respect toward the recipient. Some individuals design their signatures to make them look attractive and practical. The email signature should look visually appealing and well organized. Hence, if the signature is memorable and aesthetic, it will earn extra credit points from the recipient.

  • It consists of the sender’s name and contact details preceded by a polite phrase to denote the recipient.
  • A signature should include the full name when writing an email to a person for the first time.
  • Avoid using any flashy signature to end the email.

Comprehensive Breakdown of a Formal Email Structure

A conventional email format typically includes a subject line, greeting, body (containing the introduction, details, and conclusion), closing, and signature. Likewise, professional emails include an effective subject line that is both informative and clear, a formal greeting (e.g., “Dear Mr./Ms [Last Name]), and a closing (e.g., ” Sincerely, [your name]).
Here is an enlarged version:

  1. Subject Line
    • Make it brief and informative, letting the recipient know the email’s purpose.
    • Stay away from unhelpful subject lines or generic ones.
  2. Greeting
    • Use a professional salutation like “Dear Mr./Ms. [Last Name].”
    • If you don’t know the person’s name, you can use “Dear [Title]” (i.e., Dear Hiring Manager) or “To Whom It May Concern.”
  3. Body
    • Introduction: Briefly state the reason for the email. If you have not previously communicated with the person, introduce yourself.
    • Details: Provide the meat of the email: the information or request you are making. The body should be clear, concise, and easy for the recipient to follow.
    • Conclusion: Recap your main ideas or state what you want from the conversation.
  4. Closing
    • You will use a closing phrase, even an informal email (e.g., “Yours sincerely,” “Best Regards,” or “Thank you”).
    • After your closing phrase, use your name, title, and additional contact information.
  5. Signature
    • You may include your name and title (if applicable) and contact information such as a phone number or email.

Other Tips:

  • Proofread: Always check carefully for spelling and grammatical errors before sending.
  • Be Professional: Use clear, to-the-point language, and avoid slang or language that is too casual for the email.
  • Be Brief: Be mindful of the reader’s time by keeping it concise.
  • Attach documents: If you need to add documents, mention them in your email and double-check that they are attached before sending it.
