Thanks __(Name)__!
What you __(said/wrote/did)__ was amazing!
You went above and beyond,
you gave your time and energy,
you did everything you could to __(briefly describe – i.e. give a good review of….).
All I can say is... “That really was you who __(said/wrote/did)__ all that, wasn’t it?!”
All kidding aside, __(Name)__, your __(speech was/words are/efforts are/etc.)__ greatly appreciated and, in the words of John E. Southard, let me say, “The only people with whom you should try to get even are those who have helped you.”
Thanks again!
Warmest regards,
