When you get a job offer, your first reaction is going to be that of excitement and you will probably tell everyone you know about it.
However, the thing that can add value to your profile and increase your chances to excel at that job is a nice thank you email to the prospective employer.
In the opening paragraph, you can state that you are grateful for getting a chance, and will surely pursue the opportunity. Do not mention the details of prior job experiences in the opening paragraph, just inform the recipient as to why this email is being written. The first few sentence, however, should be catchy enough to keep the reader engaged. Many people underrate the importance of introductory sentence, but it works wonders, truly reflecting your capability and ambitions.
Talk about your job experience and the challenges you are keen to take on in the second paragraph. You can mention your past experiences (the related ones of course) and say that you are fully prepared to carry out various tasks, if given an opportunity. Conclude the email by thanking the recipient once again.
