Is the way of writing professional emails different from formal letter writing?

No. While typing a formal letter in the earlier days, the typist would include using proper grammar and their way of speaking through the message needed to come across as appropriate to the reader of the message. Now people are sending texts and emails, the same rules would apply to that as well. Emails should be written in a professional and courteous manner.

Even though people think that emails are sent quickly, they should still have appropriate grammar and spelling. Also, SPAM or jokes should not be forwarded on to others especially in a company. In an email, it should include the sender’s name, greeting and contact information, if needed.
