Business application email is sent to a person with whom you want to start a business or your preference.
Undoubtedly, it is of immense importance that you must obtain the appropriate email address of the person, so that the email is not delivered to any other person.
In the first paragraph of the email, you must give an introduction of yourself and state your desire of starting a particular business with that person.
In the second paragraph of that email, you must describe yourself in great detail so the person should have a clear image of what you really are and what you have done in the past. You must also explain your desire of starting the business with that person and what would be his role in that business.
In the third paragraph of the email, you must invite him for a direct meeting, so both of you could meet each other and discuss the possibility of doing business.
