How to write an effective email

AVOID TOO MANY EXCLAMATION MARKS AND NO EMOJIS
I find I use too many exclamation marks in my emails, usually to sound excited, but one could also read the exclamation marks as being angry, frustrated, etc. And NEVER use emojis in a work email, to anyone other than a close friend.
AVOID QUOTES THAT COULD BE OFFENSIVE TO OTHERS
More and more you see quotes at the bottom of emails. Some are benign inspirational quotes, such as “Be the best you can be every day,” these are fine; however, avoid quotes with religious meaning, quotes that could be viewed as excluding others, etc. could offend a co-worker, a client, or a vendor, which could result in the loss of productivity and business.

ALWAYS PROOFREAD YOUR EMAILS
Sending out an email with typos, misspelled words, etc., makes you look bad. Take the extra minute to proofread the email.
NEVER SEND AN EMAIL WHEN ANGRY OF FRUSTRATED
If you need to write the email, do so in a word document, where it is impossible to hit the send button by accident.
EMAIL CHAINS
Email chains can be effective, but sometimes it is more effective to pick up the telephone and have a conversation in five minutes versus four hours of back and forth emails. Also, be careful not to change content areas without changing the subject line.
LEGAL RAMIFICATIONS
Remember, your email, your colleague’s email, even the vendor’s email is subject to a warrant should illegal activity occur or a lawsuit be filed. Furthermore, emails sent to and from your work email address, are the property of your employer. Thus, NEVER put anything in an email that could compromise you or the company from a legal perspective (or from a professional perspective). This includes, but is not limited to, defamatory comments, harassment, admitting to wrong-doing, accusing someone of a crime or wrong-doing, promising a quid pro quo, and promising something that can’t be delivered (especially when it comes to products).
Countless articles have been written on how to craft effective emails, but I receive poorly constructed one on a daily basis. Part of the reason, the ability to write has been cast aside. We live in a world of 240 character Tweets and text messages, where everyone’s quote at the bottom on their email sent from their phone say something about excuse my typos. Even though we live in this world, writing is still important. These 12 tips offer a formula for constructing a effective email, which ultimately makes it easier.
Hope you will take the time to follow these rules because your emails will be better written, more easily understood, and less likely to require follow-up. In the end, this saves time and allows you to work on other important tasks.
