You have recently been appreciated by a client. Write a letter to your manager. In your letter Describe the appreciation you have received. Describe the work you have done. Ask him for a raise. You do not need to write any addresses

Dear Mr. Anthony, I am writing this letter to inform you that our product "Task Simply" has been successfully launched at all locations of our client "Synthia". Synthia is hugely impressed by our product usability and also greatly appreciated the entire launch process that was led by me. It has been a productive overall experience for me leading the launch as I got opportunity to organize, plan, design and structure the demo trainings for employees all across their company. Moreover, I took great care to execute all of these tasks within the assigned budget, out of which only 90% was spent. Although, these last 4 weeks has been very stressful, I was able to complete my assigned goal for the year successfully along with improving the client work rate by 15%. Therefore I believe, it would be reasonable for me to ask for justifiable raise for my contributions to the company so far and for more productive work in future. Looking forward for a positive uplifting response from your end. Thanks for putting your confidence on me for this project. Yours sincerely, Andrew
