Why use Slack? Slack has rate limits and one will not get the notifications when something real goes down as there will be 100s of messages overloading Slack API.

Slack is convenient just because we use it for some other purposes.

Someone else pointed out that Telegram is also a good idea - that's very easy to do. I've set up Telegram alerts for other purposes.

Rate limits are present in chat apps to prevent the service from being abused. Notification tools don't have that.
