E-mail etiquette rules every professional should follow

People have been sending e-mails since the 1980s and the numbers keep rising. There’s an art to writing e-mails, for example, when writing business e-mails, you shouldn’t use fluffy language, but rather be direct and get straight to the point. A well-written e-mail could make all the difference, so it’s worthwhile to incorporate some principles of e-mail etiquette.

How you design your e-mail depends on the purpose of the message and your relationship with the recipient. E-mails to good friends or family members are a lot more informal than e-mails you would send to business associates. A pattern will form with this group of acquaintances and language will be used that maybe only people in this group will understand. It could even be considered rude if you were to converse with a stranger in this way. Special e-mail etiquette is therefore needed when writing on a more professional level.

If you want to be taken seriously and make a good impression on whoever is receiving your e-mail, you should follow the general rules of e-mail etiquette. Two areas are important: on the one hand, content and text design, and on the other hand, the formal-technical aspects, which are important for sending the e-mail. The first point generally applies to every business letter – whether electronic or postal. The second category of rules is related to the medium and its features, and therefore only applies to e-mails.

For your e-mail to come across positively to your recipient, you should consider these points when writing:

In business writing, the following generally applies: be as informative as possible but at the same time keep it as short as possible. Most people receive countless e-mails every day and wading through them can take a while. The recipient’s day would be made a lot easier if all e-mails just got straight to the point by only providing the essential information. Make sure, however, that your e-mails don’t appear rude by being too short or lack accuracy due to missing information.

Every letter should begin with addressing the recipient. This still applies even with digital communication, although in using instant messaging services (e.g. WhatsApp or Facebook Messenger), SMS or chats, many users are used to other standards of written language. Using these services, people communicate in an informal way, just as they would if they were face to face. E-mails, however, follow another form of etiquette, and therefore need to be addressed and concluded in a suitable fashion.

It’s important to pay attention to the hierarchy and degree of confidentiality. The safe choice is to remain with 'Dear…' and 'Best regards'. Don’t try to come across as too friendly if you really don’t know the recipient well, as it may come across as unprofessional.

Nowadays, e-mails are composed a lot faster than they used to be. This is because smartphones and laptops enable us to write them on the go. You could conjure up a quick one on the train to work, but your lack of concentration could lead to typos, incorrect sentence constructions, and wrong grammar. This is no excuse, since you should always check over what you’ve written before sending it as a way of showing respect to the recipient. E-mails full of mistakes make it look like the sender doesn’t care, so why should the recipient care about what you’ve written? Many e-mail applications now come with an integrated spell check, but don’t rely on it too much.

Every text requires reasonable formatting so that the reader can understand it. This starts with the use of paragraphs, through which you structure the content and create connections. The same applies to bold and italicized words. Highlighted words stand out and show the reader where the most important passages are. But this only works if they are used sparingly. When writing e-mails, authors should make sure that the font, color, and size are legible. The aim of text formatting is to make it easier for the recipient to read it.

Abbreviations in e-mails should be used sparingly. They need to be decoded if they are particularly unusual, after which the reader needs to piece together words from the letters, which isn’t always easy compared to the usual abbreviations such as 'etc.' and 'e.g.'. Some abbreviations are so specific that the recipient might not even be familiar with them. Shortened versions of words can make the e-mail seem abrupt and alienate the recipient if they have no idea what they stand for. This isn’t the best way to get them to take your e-mail seriously.

When exchanging e-mails, it’s impossible to get your tone of voice across. The reader can’t recognize whether you’re being sarcastic or joking, which is why smileys and emojis can help in chats, but these are obviously not used in business e-mails. It is therefore a good idea to avoid sarcasm and humor and to instead use a factual and friendly tone.

When composing an e-mail, you can orientate yourself using the general rules of business correspondence, but there are some extra things to consider when it comes to e-mails. For example, the e-mail address itself as well as other aspects.

Most people don’t use their private e-mail address to send business correspondence. Using the e-mail address ilovebradpitt@aol.com that you created decades ago doesn’t give off the most professional vibe. You don’t necessarily have to have your company’s name in the e-mail address, but make sure that your full name is included. This comes across more professional than hiding behind a pseudonym. Instead of using a free provider, it’s a good idea to create your own domain. This means that not only the part before the @ sign points to you, but the following part of the address can also include the company’s name.

In many industries, employees receive dozens of e-mails daily. They don’t have time to read through each one to work out if it applies to them or not. This is when a meaningful subject line comes in handy. Keep the subject line short and make it clear what the e-mail is about. Instead of writing 'small request' or 'meeting?', make it clear what the request or the meeting are about.

The e-mail etiquette also includes behavioral rules for replying to messages. Most programs and web services display two buttons: 'Reply' and 'Reply all'. What happens here? Well, in the subject line, 'Re:' will automatically be inserted to indicate that it’s a response (or reply). Lastly, the programs insert the original content of the e-mail in quote form into the text. The recipient’s e-mail address will then appear in the address field and you can choose whether to reply to just the one address or also to the other addresses who received the source e-mail). What do you exactly have to consider when replying to an e-mail?

• Reply all: Always ask yourself before you hit the 'Reply all' button: will all these recipients find my reply interesting? You can save many people from doing unnecessary work if you only send your answer to those who will really benefit from it.

• Re: This shows the recipient that this e-mail has something to do with their original message. If the recipient answers again, it will change to 'Re: Re' and so on. You can delete this from the subject line if it starts to become too much.

• Quoting: The same applies to text quoted from original e-mails. In longer conversations, it’s easy to get confused when so much text is being quoted. It can be useful to clean it up, but be careful when you do. You should always quote important information when referring to it, so make sure you don’t delete it.

There’s not really an ideal amount of time to wait for answering an e-mail, especially because you don’t know when the sender checks their mails. E-mails are sometimes sent back and forth so quickly that it seems like both parties are under time pressure. If the sender needs an answer right away, it might be better to call them.

If you already know that you can’t answer within the next 24 hours and it seems like it’s important, you could write a quick e-mail back to confirm that you are interested, but will reply in more detail when you have the time.

A common function of e-mail services is Autoreply, which is an automatic response to all incoming messages. You should write the text in advance, which will then be automatically sent to anyone who writes to you. This function is especially useful if you aren’t able to answer you e-mails for a long time, which is why it’s referred to as the out of office notification. This enables you to inform others about the duration of your absence if you are on holiday, for example. Do not forget to deactivate the automatic message upon your return. Under no circumstances should Autoreply be set up to send acknowledgements of receipts.

If you format the text well, it makes it a lot easier to read. HTML offers you numerous ways to design your e-mails: they can be enhanced with images and other multimedia files, for example. This is why the use of HTML codes in e-mail marketing is very popular. Although using HTML in e-mails isn’t totally problem-free:

• Display errors: If you’ve ever created a website using HTML, you’ll know that it has to be tested in different browsers. Only then can you be relatively certain that the desired layout is being displayed to every user. This problem still exists when it comes to e-mails. They can be read on different web interfaces using different browsers or programs both on the desktop and on mobile devices. It’s highly likely that the HTML-formatted e-mail will be displayed to some users as random letters, which doesn’t happen with simple text formats.

• Security: Including HTML in e-mails is always being criticized. Viruses and worms can infiltrate through the code. Therefore, users often set their clients (such as Outlook or Thunderbird) to block HTML elements and to display rich text only. However, this can lead to display errors. If you stick to a simple text e-mail, you can make sure that the e-mail is displayed to the recipient exactly as you planned it to be.

Many people devote little time to their e-mail signature, or don’t use one at all. This is an e-mail etiquette basic and for this reason, creating a signature is very important. The signature should provide the recipient with the following information about the sender:

• Full name
• Position within the company
• Address
• Telephone number

This information is especially important if it is the first time contacting the person. This means that the recipient can also reach you quickly by telephone or by post. In addition, any other possibilities of contacting the sender should also be included in the signature. For example, links to social media channels or the company website. The signature can also be adapted using HTML codes. However, this can lead to the same problems as with formatting the e-mail text using HTML. If you decide to use this code, you could add the company logo, for example. E-mails can also be digitally signed so that the authenticity of the sender can be verified. However, the signature of the business e-mail is NOT the place for your life mottos or favorite quote.

For normal company post, there are also attached documents that are sent along with letters, and this isn’t much different regarding e-mails. You can expand you e-mails by adding files into the attachment field. Here’s the etiquette for sending attachments:

• Consider the file size: Just because your e-mail inbox allows you to upload large files, it doesn’t mean that the recipient’s inbox can receive such large files. Therefore, you should not send files over 5MB by e-mail (or only after consulting with the recipient).

• Pay attention to the attachment’s file format: Just because you work with a certain format every day, don’t expect the recipient to also use it and have to right format to open the file. As for text files, you should send PDFs instead of Word files. The former has the advantage of being able to be read no matter the platform, and usually don’t allow themselves to be edited. Word documents, on the other hand, are dependent on the version of software being used and the fonts installed, so the recipient will often see the file differently from how you intended.

The best e-mail etiquette rules are useless if you don’t follow them properly. Therefore, the most important tip is: read through each e-mail before you send it!

• Are the e-mail addresses entered into the recipient field correct?
• Are you sending the e-mail from the correct account?
• Are you addressing the recipients correctly?
• Have you checked spelling, punctuation, and grammar?
• Have you remembered to attach the files?

But what if you do make a mistake? You can either quickly send an e-mail apologizing for the error, or you could call them up.

Many people lean towards e-mails even though a quick telephone call might have sufficed. This is especially the case when there are pros and cons to be discussed, since sending e-mails back and forth could cost unnecessary time. It makes more sense to quickly clarify something in a five-minute telephone call rather than starting an e-mail conversation, which could go on for days. You should refrain from sending an e-mail if the conversation threatens to turn into an argument. Writing an e-mail when you’re angry or upset is not the best idea. In cases like these, oral communication is a better strategy to make sure the person you’re conversing with doesn’t misunderstand you, causing the situation to escalate. When you choose to send an e-mail, you must also remember that its contents can be saved for a long time. You don’t have any influence on what the recipient does with the e-mail, where it gets saved, or who it gets forwarded to. You therefore have to carefully consider whether to include sensitive data in an e-mail or not. Even if you think you trust the sender, the e-mail still poses a security risk: to avoid being spied on by third parties, you should encrypt your messages securely with SSL or PGP.

The perfect business e-mail is written in an informative and polite way. For this to apply to your e-mails, you should invest some time in writing them. Your effort will pay off, since a message that adheres to e-mail etiquette comes across much better that one that’s been written quickly and is full of errors. In the long term, e-mail etiquette also helps to develop positive business relationships.
