We take the approach that most presents aren't from Santa. They're from the people they're from. And Santa leaves a small present along with her stocking on Christmas morning (so all the presents under the tree are from us or other friends/family, not Santa). If you want to have more presents from Santa, that's fine, but I would definitely emphasise that the presents that are from actual people she knows are from them and she can say thank you to them or write a thank you card to send. In our house, we leave mince pie and carrots and a drink for Santa and the reindeer as a thank you (and then her little present and stocking get left on the window sill next to that). So you could do that and write a little thank you to leave with it or I think just having them say thank you (they could shout out the window after opening presents!) is nice too.
