Though emails usually aren’t as formal as letters, but they still need to be professionally written to give a good image of you beside your organization/institution. Presently as a student or later when going through the professional journey, transacting by writing e-mail is one of the essential methods of communication. The salient points in writing email are enumerated as follows; -
1. Always use a professional email address. Ideally, your email address should be a variation of your real name, not a username or nickname.
2. Adhere to 5 Cs of business writing; Clear, Credible, Concise, Coherent and Compelling.
3.  Follow 4 steps of writing to convert an idea into description: 
a. Think about what you’re going to say and the reader(s)
b. Write a first draft
c. Review and edit what you’ve written
d. Use spell check/Proof-read
4. Be positive and be courteous. Manners cost nothing. By using pleasing & positive words make you connect to the recipient instantaneously. 
a. Look at these words (correct words): helpful, good question, agreed, together, useful, I’d be delighted, mutual, opportunity
b. Now look at these (incorrect words): busy, crisis, failure, forget it, I can’t, it’s impossible, waste, hard
5. The words you use show your attitude to life so choose your words wisely.
6. Simple steps to make sure emails are perfectly professional.
a. Begin with a greeting
b. Thank the recipient
c. State your purpose

e. And then close
7. Respect readers time, so ‘Keep It Short & Simple’ (KISS).
