Dear Jack Martinez,
I would like to inform you that the package you sent last week containing the hard drives has arrived safely in my office and was received by my secretary this morning.
Upon checking and briefly scanning the contents, it seems that everything is in place and in good working condition. I will start with the project immediately and update you at the end of each day on what I have accomplished so far.
I appreciate the confidence you have in me with regards to this project and will do my best not to disappoint you. Thank you again for the opportunity.
Sincerely,
Taro
