New Datadog integration for Courier notification logs and metrics

Robert Fenstermacher

April 11, 2023

The ability to unify all notification metrics and logs across channels and providers into an easy-to-use dashboard is a core advantage of Courier’s notification infrastructure.

However, with product notifications so critical to the entire application experience, it’s important to connect that data back to central cloud observability platforms that look across the entire stack. This gives platform engineering teams a complete understanding of application health and lets them quickly troubleshoot even the most complex issues.

Today, we’re incredibly excited to announce our first observability integration with Datadog.

Datadog is a tool for collecting metrics and other data from applications and viewing them in a centralized place. Datadog’s dashboards and monitoring tools build a more accurate picture of the health of your application and how it changes over time.

Our integration with Datadog is easy to spin up when you use our “dashboard starter kit.” This consists of some pre-configured JSON to set up a simple dashboard in Datadog for your Courier data.

Our Datadog integration is currently only available on Courier’s Business plan, much like our other production-focused features such as template analytics, Okta integration for SSO, and advanced user preferences.

The fastest way to pull your notification data into Datadog

Courier's message logs and analytics dashboard are optimized for helping product teams understand everything about the messaging use case — the status of notifications, recipients, lists, automations, and more. It brings all this data together across channels and providers in one place and provides the fastest way to learn about your notifications and troubleshoot notifications-related issues.

However, many organizations need to understand how notifications interact with the rest of the tech stack or would prefer to view and store all logs and metrics data in one place.

Until now, the only way to pull this data outside of Courier was to build your own bespoke solution, by listening to Courier’s outbound webhooks and writing custom code. But now the Datadog integration enables sending information about health and performance directly to your own monitoring system, which is much more convenient.

Use cases

Notification metrics and logs

The most obvious use cases involve sending data about the health and delivery status of your notifications. This could include metrics such as:

  • Percentage of messages that are successfully sent, delivered, opened, and clicked.
  • Delivery errors
  • Percentage of customers who are unsubscribing from your messages
  • Any metrics that measure outliers — for example, a metric that checks if you are sending either more or fewer messages than you should be.
  • Number of people who opened your emails over time.

notification-observability-delivery (An example Datadog dashboard showing key notification health metrics, such as the number of emails and push notifications that are being sent over the course of the day)

notification-observability-engagement (Datadog graphs showing how many notifications are being opened and how many people are clicking on links. There are options to compare these metrics to other time periods such as the previous day, week, or quarter.)

Feature-specific metrics and logs

The integration also supports data from Courier platform features. This can provide even more color on how notifications support your business or operational goals. For example, If you use Courier Automations to build smart notification workflows, you may want to monitor how many times each automation has been invoked. Or, if you use Courier’s in-app notification Inbox, you might choose to monitor the number of connections to your Inbox and compare this to the number of active users on your site. A significant difference could indicate a problem that needs further investigation.For example, you might have released a change that broke your Inbox implementation through changes to an authentication method or a key.

What data can be sent to Datadog from Courier?


Courier metric names will have a courier.* prefix — for example, courier.notification.sent. A full list of all the Courier metrics that are available for you to send to Datadog is provided here. These metrics will be sent with additional information, such as success or failure codes, and tags (including whether the metric is for your production or staging environment).

Once the metrics are being sent to Datadog, you can set up corresponding alerts in Datadog. For example, you could set up an alert that emails your engineers when the number of notification delivery errors reach a certain predefined threshold.


Courier always had the ability to record logs about notifications, recipients, lists, and automations. Now these can be sent to Datadog in the same way that metrics are sent.

Courier’s logs provide details about delivery failures, as well as other information that can be relevant when debugging. With these logs now in Datadog, you’ll now be able to easily correlate the logs to your metrics, helping you debug any issues.

Setting up the Datadog integration

To set up this integration all you need is your Datadog API key and URL. From there, simply follow the setup guide, which will cover the steps to connect Courier with Datadog and how to create a Courier-specific dashboard in Datadog. This is where you’ll find our “dashboard starter kit,” a JSON file that has everything you need to set up a Courier dashboard, including commonly used Courier metrics. You can easily customize the JSON to add or remove different metrics according to your needs.

Next steps

If you’re already on Courier’s Business plan, you can start sending metrics and logs to Datadog right away. Otherwise, you can request a demo, and we’ll walk you through this integration in more detail, along with the other features in the Business plan to see if it’s right for your use case.

The ability to access your metrics and logs in an observability platform like Datadog allows you to set up a dashboard that shows the data that’s most important to you. You can also create graphs that enable you to see at a glance if something’s not right, or even set up alerts based on message delivery failures. Whatever size your business is, some level of monitoring is necessary if you want to have control over your application.

If you’re a Datadog user who is interested in trying Courier’s full-featured notifications infrastructure, you can try it for free.

Courier Inbox for web and mobile, a complete notification center

A notification center inside of web and mobile apps is now an expectation. It’s a way to reach specific audiences or users with tailored messages and a way to boost engagement by bringing people back into the app. While Courier has been adding Inbox capabilities over the last couple years, we’re excited to announce a complete set of SDKs that span web and mobile. You can drop in a full-featured inbox to give your users a best-in-class notification center inside your app that works seamlessly with your existing notification flows.

Controlling notification send limits in Courier

Send limits are a new addition to the Courier app that allow you to manage notification rate limits. This means you can set a maximum limit on the number of notifications you can send over a certain time period. The advantages of using send limits are twofold: you can save money by imposing spending caps on notifications, and you can improve the customer experience of your app by avoiding bombarding users with too many notifications at once. Send limits can be applied in a variety of ways, including system-wide notification limits, as well as specific limits for individual users or notification topics. For instance, you can set an overall limit of 200,000 notifications per week. This article will explore the various types of notification rate limits available, explain when send limits are useful, and provide guidance on how to set them up.
