Dear Ma’am/Sir;
Greetings!
I am currently looking for a job when I was noticed that your organization has vacancies and I am interested in applying for an Administrative Assistant position. I can say that my skills and experience could make a great contribution in your organization. I am also willing to do extra work that you will give to gain more knowledge.
I would appreciate the opportunity to discuss my qualification in greater detail with you in person at your earliest convenience. My resume is attached to this email.
Thank you!
