How to make a bad texter be better?

My new partner is a horrible texter, I knew this going in. Sometimes it'll take him an entire day to respond. Or he'll wait until he sees me to respond in person. I'm guilty of it too with everyone, not just him. But I'm actively trying to be better. Communication is important to me, especially in this early stage. It makes me more sad than upset that.

I know he cares for me, it's in his every action when I'm with him. But how do I get a bad texter to be better?
