I have never sent CAB materials post meeting. Everything is done under NDA and forward looking materials and they could share internally with people who haven’t signed NDAs. That has always been my policy.
I’ve also sent thank you gifts for example: a package of items from the place we went to, some wine (for drinkers and non-wine gift for others), credit to our company store to buy an item or two, a gift card to an online shopping site they can buy a nice item from). And always send a thank you email right after from a sales executive!
