to handle customer support/customer success, I can tell you that Slack is probably not a tool that will allow you to scale!
Here's why.
When you do customer success, you usually have to have multiple people in the team handling a customer ticket.
You need to be able to quickly reference other tickets and run automation to be effective.
I use Slack daily and have used it since the early days: Searching for things on Slack sucks plainly. Threading is either you love it or you hate it. You want to flag a message to another person -so they can see it later, perhaps because they're in a different timezone GOOD LUCK.
A parallel could be this: imagine not having A/C and living in hot country like Texas... yeah not fun if you're trying to be productive now is it. (source: me, I tried. NOT FUN)
