Yes, we definitely consolidate (and normalize) state for deliverability, opens, and clicks across providers and channels. One interesting thing we do here is for channels like Slack & Teams that support webhook-based click interactions natively: we offer you a webhook proxy so clicking the "Approve" button on the Slack notification will hit Courier first (so we can count it as a "click") before proxying through to your approval handler. All of that data is then normalized in our logs, which you can view in our UI or have streamed to your systems via webhook.
