1. Be concise and to the point
Emails are harder to read than printed communications so a long email can become a daunting task.
2. Use proper spelling, grammar & punctuation
Improper spelling, grammar and punctuation can give a bad impression of your company. Also, if there is no punctuation then the meaning of the text can change from what you were trying to convey.
3. Answer swiftly
An email reply should come within at least 24 hours. When someone sends an email they prefer to receive a quick response otherwise they would have sent a letter. If you need time to come up with a response you should at least send an email saying that you received it and you will get back with them as soon as you can.
4. Do not write in CAPITALS
WRITING IN CAPITALS MEANS THAT YOU ARE YELLING AT THE RECIPIENT. This can trigger an unwanted response from the person that you sent it to. If you want to make certain words stand out use in bold font maybe?
5. Read the email before you send it
This is very important! You need to read it as if from the eyes of the recipient, that way you will notice any grammatical errors as well as sentences that can be misconstrued.
6. Take care with abbreviations and emoticons
When sending business emails, try not to use abbreviations such as LOL(Laugh out loud) or BTW(by the way). The recipient might not be aware of the meanings of the abbreviations and in business emails these are generally not appropriate. The same goes for the smiley emoticons.
7. Use a meaningful subject
Make sure to use a subject that will make sense to the recipient as well as yourself. Do not be vauge. If the content changes during the course of the email exchange, then change the subject of the email.
8. Avoid long sentences
Emails are meant to be quick and concise, so keep the sentences down to a maximum of 15-20 words.
