Any of you - OVER automated? Where's the Line

I was thinking about this as I'm reconfiguring our sales intake system. We are about to implement a system that will automate a lot of follow up and keep nudging people that haven't responded. I'm trying to do the same with email, and occasionally will send voice texts also. But when is it too much and you've lost the human touch?

I definitely don't want to take the personality out of my business. Where have you drawn the line in your own business to keep the machine from running the whole thing?
