Mila, I am so sorry for your loss. Pets become part of our families and losing one is devastating.
I think your email of appreciation is wonderful. I'm new at this myself, but thanking him again for what he did for you in this sitch isn't going to hurt anything. I acknowledge anything my H does that is positive with a thank you. It let's them know they aren't being taken for granted. Just my 2 cents.
