i would try to set your own boundary and not email every day, i can not fathom emailing anyone every day, it comes off very needy or clingy.

maybe make yourself a goal of every other, than 3x a week then 2 etc. i have been able to cut back drastically myself by creating my own goals

that being said, i have no idea why she is not responding but maybe she is trying to be nice and is overwhelmed by them now. no idea.
