Getting on top of how emails are used in your company is really important, as they're often used as the main form of communication.
Key email basics are:
Be responsive! Try to respond to emails as quickly as possible.
Be succinct! Make sure your responses are edited and clear.
Be thoughtful! Know your audience - if they tend to be very polite and formal, write in that language.
Getting more specific, there are key elements of emails that you should be aware of:
Subject Line: The subject line should concisely convey your purpose for writing. Your subject line can be as simple as "Thank You" or "Request for Recommendation".
Greeting: Even if you are writing a very short email, include a greeting. If you know the name of the person, include it, e.g. Hi Marie, or Dear Marie (if you are less familiar with the recipient).
Length: Keep your email as concise as possible. People tend to skim long emails, so only include essential information. Try to bullet point your key messages if you can.
Font Style: Avoid ornate, playful, or coloured fonts; these distract from your message. Also avoid overusing bold and italics as well, which make an email look cluttered and don’t write in all capital letters either; this comes across as angry or overexcited in an email.
Spelling and Grammar: Edit your email carefully before sending it.
Closing: Sign off with a brief "Thank you," "Warm regards," or other simple send-off, and then your name.
Checklist: Before you click send, double check to make sure:
The subject line of your email is filled in
You are sending the message to the right contact person
You have filled in the Bcc field to send a copy to yourself so you have a record of the email message
Spell check and check your grammar and capitalisation.
