How fast do you really respond to customer support tickets as a solo or small founder?

For a long time I treated everyincoming support message like an absolute emergency. It was exhausting and constantly pulled me away from actually building and fixing the product.

When I was forced to slow down my response time recently nothing broke. In fact churn didn't go up at all and users started using our docs instead of waiting on me.

It made me rethink my whole support strategy. Curious how other founders handle this what’s your realistic response window and have you noticed any downside to taking a few hours to reply?
