What are some tips on writing the perfect business email?

You can find many different resources online that talk
about successful tips in composing business emails.  A simple web search might be
immensely helpful here.  I think that one of the most direct approaches would be to
maintain proper grammar and writing skills.  It is important to not compose emails with
the same technique that text messages or Tweets are composed.  "You" instead of "u" or
"Later" instead of "l8r" would be examples of this.  It takes away from the business
format when the message is a casual text and not a direct business communication
method.  Along these lines, spellchecking your email would also be a very good step to
take.  Emails that are filled with mistakes of spelling and composition present
themselves in an unprofessional manner.  I think that the use of the "Subject" section
of the email can also be an important element to add to the professional nature of the
business email.  Being able to provide a pertinent, direct, and meaningful subject
heading in a succinct manner can allow for focused communications with clients or
colleagues.  This can help to facilitate a proper business sense to your
emails.
