Even before you are stepping into a career field, you likely know— or at least think you know—the basics of email etiquette. However, it is always a good area to review before you start emailing a new colleague, boss or professor.

The average person spends just under a third of their workweek reading and responding to emails, according to a 2016 study from SaneBox. The study also found that 205 billion emails were sent and received each day in 2015 and expects that number to grow in the next few years.

How you craft an email says a lot about you. It can show how much attention you pay to small details, the amount of respect you give the recipient and your level of professionalism.  So, before you press send, make sure you follow the tips below.

Use an email signature

Instead of just signing an email with your name, put any titles you hold or contact information below it. This shows your involvement with not only the company, but other projects are working on. The recipient can also get an idea of what they should contact you about.

Fill out the subject line

A good email subject line will clearly preview what the email is about. Without it, the recipient will not know what the sender is talking about before opening the message and might not open it right away. Make sure you always have a subject line in your email. Plus, writing the subject line first can help you focus on your main point when writing long emails.

Proofread messages before sending

This may seem like common sense, but before you send an email, make sure you read what you wrote. You might catch small grammar mistakes or see that you forgot to add the attachment that you were referring to in the text. A simple edit will not take more than a minute on most emails.

Respond to emails sent to you

After sending emails, you will find that you will start receiving them. Be sure to respond to emails in a timely manner. Most usually respond to business emails within a day.
