Dear Mr Colony
I hope that everything is well with you . I am writing to inform you that I will resign by the end of the month.

The company did not appreciate my project. I recently heard that you are going to adopt a new one.
Having seen your advertisement on the internet, I make sure that my project is out.

It was my pleasure to work with you .It was a good experience but unfortunately it did not complete.

Please let me know what action I propose to take for resignation.
Thank you for your time.

Best regards مع أطيب التمنيات
