Love to see your email filter that separates messages from helpful users from demanding users.
If you can't automate this step, you have to read the insults, and pleading, and jerk-faced comments from the demanding users. Which takes time and energy.
My filter is my brain. I just... don't interact with people who don't seem worth interacting with.
And, look, that's not perfect and I'm not saying that it's not unpleasant. I'm saying that it's materially different from every person who uses your service costing you actual dollars. And if you can't see that, I honestly don't know what to tell you.
If you filter who can complain, you do not have to deal with those that you do not care about.
SAAS with free tier does it this way:
* To contact support via non-app method you need a PIN. PIN is displayed when you login into your paid account. Don't have a PIN? Can't connect to support.
* To contact support via app method your profile needs to be associated with a paid account. Don't have a paid account? Can't contact support via inapp
