Despite all the new means of communication that are available, email remains a crucial tool. Whether you’re reaching out to colleagues, recruiters, clients, or even family and friends, it’s important to know how to compose an email properly.
Although it may seem like a simple task, writing an email requires more thought than just typing a message and hitting “Send.” Poor email etiquette can lead to miscommunication, misunderstandings, frustration, and even damage your credibility. On the other hand, professional, well-structured emails can help you convey information effectively, make a positive impression, and build strong relationships.
This guide takes you through all the important aspects of email etiquette: from the perfect subject line and structuring your message to the correct use of CC and BCC, checking spelling and important details, replying to and forwarding emails, and managing your inbox efficiently.
And if you’re wondering whether you still need these tips in the age of ChatGPT and similar AI tools, we assure you that you do. Clearly, you shouldn’t send an AI-generated email to anyone without reviewing it to make sure it complies with the best email etiquette, both in terms of content and structure.
Basics of email etiquette
Emails serve a variety of purposes, from professional inquiries and business negotiations to occasional updates and personal messages. It’s important to know when to use email and how to use it properly.
What you should know is that emails are ideal for formal communication, documentation, and messages that don’t need to be answered immediately. For urgent or highly sensitive conversations, phone calls or messaging apps are more suitable.
The main difference between personal and professional emails lies in the tone, structure, and degree of formality. Personal emails are more casual and often contain casual language, emojis, and abbreviations. Professional emails, on the other hand, require a polished tone, correct grammar, and a clear, structured format. If you know these differences, you can ensure that your emails meet the expectations of your recipients and present a good image of yourself.

Writing a well-structured email
Subject line: The first impression matters
Your subject line is very important because it determines whether your email is ignored or opened. A vague or unclear subject line is ineffective and can come across as unprofessional, whereas a well-crafted subject line conveys the information in an engaging, professional way.
For example, instead of writing “Meeting” or “Question,” a more effective subject line would be:
- Inquiry about job opening at XYZ
- Follow-up on project proposal – Due April 15
- Request for availability: Marketing strategy meeting
A good subject line is informative and concise and helps recipients prioritise their responses.
Using proper greetings and addressing recipients correctly
The way you address your recipient sets the tone of your entire email. In a professional setting, it is advisable to start with a formal greeting, such as:
- Dear Mr. Smith,
- Hello Dr. Johnson,
- Good morning, Team,
Avoid overly casual greetings such as “Hi there” or “Hey” in professional emails, unless you already have a friendly relationship with the recipient.
Spelling names correctly
Misspelling someone’s name is one of the most common mistakes in email etiquette that can be easily avoided. Always double-check the spelling of names before sending an email, especially when contacting someone for the first time. If the name has an accent or a special character (e.g. José, Zoë, Michał), you should make an effort to spell it correctly.
Using CC and BCC wisely
You can use the CC (Carbon Copy) and BCC (Blind Carbon Copy) fields to include additional recipients in your email, but they should be used with caution.
- CC (Carbon Copy): Use this if you want to inform several recipients who do not necessarily have to reply.
- BCC (Blind Carbon Copy): Use this when sending an email to a large group where the recipients don’t need to see each other’s email addresses.
Avoid CC’ing unnecessary people as this can lead to clutter. Also, use BCC wisely so that no one feels left out.

Writing a clear and concise message
Double-checking important information
A professional email should be error-free and accurate. Always double-check important details before you send your email. This includes:
- Dates and times: Miscommunication about a meeting date can lead to missed appointments.
- Addresses and phone numbers: Even a small typo in the contact details can cause confusion.
- Attachments: Make sure you have attached the correct files before sending.
If you check your email properly before you click “Send,” you will avoid unnecessary back-and-forth messages.
Replying to and forwarding emails professionally
Timely responses are very important in a professional environment. If you receive an email that requires a detailed response but you need more time to gather information, it is best to acknowledge receipt and provide an estimated response time.
Use “Reply all” with caution. It makes sense to use it when all recipients need to be kept in the loop, but unnecessary use of this feature can lead to email clutter and give the impression of unprofessionalism.
When forwarding emails, always provide the necessary context. This way, the recipient understands why they are receiving it. Also remember to remove any irrelevant or sensitive information before forwarding an email.

Email signatures and contact information
A well-crafted email signature adds another level of professionalism to your messages. It should include your full name, title, company, and contact information. If applicable, include links to your website or LinkedIn profile.
However, keep the signature concise, as too much information or large images can be distracting. You can include your picture in the signature if you want to increase your credibility. And don’t forget to update your contact information regularly.
Managing your email inbox efficiently
A cluttered inbox can lead to inefficiencies and missed emails. Organise your emails using folders and labels to help you manage your messages more effectively. To reduce inbox overload, unsubscribe from unnecessary newsletters and use email filters.
Use automatic replies and out-of-office messages strategically. Set up an automatic reply if you will be unavailable for an extended period of time. Let senders know how long you will be away and provide alternative contacts if possible.
Adapting email etiquette for different cultures
In a globalised world, email communication often crosses cultural boundaries. Different cultures have different expectations in terms of formality, tone of voice, and response times. In some cultures, more detailed responses are appreciated, while others prefer brevity.
Language sensitivity is another factor you should consider. Avoid using slang or idioms that may not translate well, especially when communicating with international colleagues.

The future of email and modern alternatives
With the rise of instant messaging and collaboration tools such as Slack and Microsoft Teams, the role of email is evolving. While these tools enable fast and efficient communication, email remains the preferred choice for formal business correspondence, record-keeping, and official documents.
AI and automation are also playing an increasingly important role in email communication. Automated responses and smart filters can increase efficiency, but should be used with caution. If you rely too much on AI-generated responses, emails can come across as impersonal and lead to errors if they are not checked carefully.
