Use The right Subject line

Always use the relevant subject line for your email. Never use a subject like ‘Hi’, ‘Hello’ or other general words which does not convey the essence of your mail in few simple words. Also do not send a mail with no subject as this will not give any idea of your mail to the reader and he needs to open it to find the contents of it. This will not only wastes his time but also sometimes annoys him. Use only few words as subject relevant to your email purpose from which the user must get a little idea of what the mail is about and its priority.
