"I appreciate your support" is correct and usable in written English. It is often used to express gratitude towards another person for something they have done that has been beneficial. For example, "I want to thank you for all your help with this project; I appreciate your support.".
To the Editor: Re "After the Space Shuttle" (editorial, July 22): As one of the most enthusiastic supporters of human spaceflight for 60 years, I appreciate your support of a "far more ambitious set of manned voyages" to follow the end of the shuttle program (which did, indeed, fail to live up to its promise) and "inspire a new generation".

I appreciate your support.
I hope you know how much I appreciate your support.
"I will appreciate your support in this effort and will keep you apprised of the events as they unfold".
I really appreciate your support.
To those behind me in my third grade mayoral campaign, I still appreciate your support.
Awesome tool! I started using it one year ago and I never had to look for another app
