Email mailing lists were awesome. I could filter them by keyword and search easily, and finding one result would show me the entire chain of the conversation.

And if your corporate IT wasn’t completely nightmarish about locking it down you had multiple client options on almost every platform.

Besides, there were tons of integrations, scripts already available, and it is super easy to write your own irrespective of what scripting language you know.

Technically it sucked in that it could, when used terribly, clog up an entire network (such as the infamous NHS mail chain reply fiasco from a few years ago), but I have no clue who decided Slack was better than emails for what emails did.

Slack is better than Lync and similar corporate messaging platform. But that’s not what people tried to sell it as, or for that matter, Slack advertising sells it as. They sell it as an alternative to email.
