However, there are drawbacks too. Like, you can be misunderstood easily. The reader can also get the tone wrong though you never would've meant it. The reader can and will read in between the lines, which can not be clarified there and then, leaving a mark most of the time. And, the worst of them all, emails are living proof that "You Did Say It"!!!. When you talk face to face, there is no proof unless it has been recorded, of course.
The last two days have taught me a lesson to proof read my mails before I send them out and that I should never ever be brash in emails.
