Just because you are writing an email and not a formal letter doesn’t mean you can drop the need for writing properly. Whether you are writing an email or a formal report, good grammar and spelling are essential.
Glaring mistakes in your style or ability to use the English language throws a dim light on your competency as a professional person. So if you are writing to a customer with a major proposal and fail to use proper grammar, your proposal not only looks sloppy but also appears not very well thought.
If you feel that you do not have good writing skills, or you have poor English skills, for goodness sake take a writing course. If you don’t know when to use a semi-colon compared to using a colon, then it’s time for some revision.
One final Thought
While it might be alright to abbreviate your SMS messages, it’s not when you are using Email.
