Do you send thank you email to your client when project is about to end?

When you are about to finish a client project, it is a good idea to prepare a "thank you" email, have it checked and send it to your customer (usually the Product Owner) on the last day. In this email include:

Make sure you have completed all requirements
Thank for the time and tell them the reasons why you enjoyed working on this project
Prepare a list of future improvements you can think of that can be done

There are a number of reasons why this is important:

It shows that you care about your client/project
Give them something to think about. They might get you back to fix the problems you have identified
Show that you will be supporting them after the project ends

Below is a template email you can use:

Hi Bob,

Thank you very much for your time for the last xxx weeks. I think you must be the best Product Owner I have worked with at SSW (always available for me when needed). I really enjoyed this project.

I believe I have completed all of your most important requirements. I had good look at the source code and while it's fresh in my mind, I thought I might send you the following suggestions that would make it easier for myself and other developers in future:
