Push notifications keep users engaged, but setting up a solid system can be quite the challenge. We're talking in-app notifications, emails, SMS, and even social media pushes – it's a lot to handle!
So, how does it all work?
🔹 First off, the business services send notifications to the gateway. It can handle them one by one or in batches.
🔹 Next, the distribution service takes over. It validates, formats, and schedules the messages based on user preferences and templates.
🔹 Then, the notifications head to the routers (usually message queues) for smooth delivery.
🔹 The channel services take it from there, making sure the notifications reach users through various channels – in-app, email, SMS, social media, you name it!
🔹 Finally, the tracking and analytics service keeps an eye on the delivery metrics. This way, the operations team can check out the reports and make the user experience even better.
It's a complex process that we often take for granted.
