Keep a Customer Up to Date on Progress — Letter-Writing Tutorial


This can be a good public relations letter and can update a client or customer on a long-term project or it can serve as a reminder of the value he or she receives from your service. The letter should be brief, offer specific details, and avoid a sales pitch.


1. Briefly explain your reason for writing the letter.


  • Enclosed is a summary of the projects Doe Insurance has worked on for your company in the past year.
  • I appreciated meeting with you Monday to discuss the possibility of buying electronic circuits through us.
  • I wanted to inform you of our work to update your computer tracking system.
  • I thought you would like to see "before and after" pictures of our technical writing seminar last week.
  • Thank you for your phone call last week regarding our progress on developing the Doe Whipper.

2. Give specific details that describe the work you are doing for the client or the value he or she has received from the work you have done in the past.


  • As you will note, your overall insurance costs were down this year by ten percent. I am especially pleased that our new efforts to track the progress of injured workers have reduced absenteeism from injuries by an average of two weeks.
  • I have faxed your specifications to our Springfield office. Because they will need to obtain a government permit, negotiate an agreement with an independent manufacturer, and establish a per item price, I don't expect to hear from them for a month.
  • As we discussed in our preliminary meeting, the updates are so extensive that they require us to rewrite the code for your current system. The code is now rewritten so that it supports all the functions you currently use. We expect the updates to be completed by August 31.
  • For a week before and after the seminar, each engineer kept a log of his writing by type, time, number of revisions required, and level of difficulty. The results are tabulated on the attached report. As you will note, the number of revisions have been reduced for every type of writing, resulting in a decrease in the writing time required--sometimes by as much as one-half. In addition, the perceived level of difficulty decreased in almost every case.
  • Research and Development informs me that they have not yet made their final selection for "Best New Toy." The Whipper is still a serious contender, but the team won't be announcing the winner until the Spring Toy Fair.

3. Close with a look toward the future, an invitation for the client to contact you, or a time when the client may expect another report.


  • We are proud of our record this year. If you have questions regarding any part of the report, please don't hesitate to give me a call. I am excited about starting another year working together to make your insurance costs the lowest in the industry.
  • I will phone you as soon as I hear from John. In the meantime, if I can be of any further assistance, please call me. I am excited to be working with you on this project.
  • I will phone you next month to set up a time to demonstrate the new system to your department. Any future updates will be added to the code very easily. I look forward to seeing you in September.
  • These figures represent a substantial savings to your company. With such results, I am confident you will want to continue to use our writing courses. I will check back with you next week regarding your needs for this winter.
  • I hope to see you at the Fair. If your design wins, it will be a pleasure to work out the production details with you. If for any reason it does not win, I hope you will continue to send us your excellent designs.
