First, I love the stats. Being able to see what went to whom and when and who opened it and whether it was delivered or blocked or rendered, etc - ALL. CHANNELS. IN. ONE. PLACE. This is brilliant. It's so much more useful for me than logging into five different places to see what's going on. Second, I can ensure that mutiple delivery methods have the same feel. And, third their documentation is fantstic - it really helped us build our slack notification capabilities. Their support is fantastic - they're regularly in touch and proactive in helping us achieve what we're looking to achieve (for instance, microsoft teams integration is a big one on our list and very complicated - I had asked them in the past for any information they had on doing this, and they proactively reached out to share their updated documentation once they released it... that's great service :) .

Courier offers a lot of flexibility and focuses on getting the message to a client and not worrying necessarily about the method. The channels and shared content libraries offer seamless integrations and notifications using both email and sms for example.

Courier bridges the gap between development and product teams and saves time since it provides a hassle-free way of designing and deploying new notifications.
