I am glad you did this (for me, for the company, for our family) is not really the best way to express gratitude. It is something to say, at best, when you tolerate what was done, when you think it was not necessary yet did not hurt, when it’s about something you are quite neutral about.

Thank you is more simple and gets to the point instead. Say it often, make of it a habit, and truly mean it. Gratitude is a muscle that can be trained.
