You can manage your notifications from the Dashboard Notifications page. You can customize which notifications you receive and where they’re delivered.


Notifications are sent to “Channels”. We currently support Email, Slack and Microsoft Teams. The channel list is on the right-hand side of the page. You may see your existing channels, the number of notifications they’re subscribed to, and the ability to create new channels.

Notification Types

On the left-side, you’ll see each type of notification that can be sent, settings, and which channels to send the notification to. You can route different kinds of notifications to different channels. For example, you can send the Daily Summary to the full dev team, but New Errors perhaps only to the front-end developers.

Both the type of Notifications and Channels are configurable per application.

Daily Summaries

Sent daily at a configurable time via email. This notification contains error rate, error delta, top errors for various categories and other information. It’s a rollup view of the previous 24 hours. It can only be sent to email channels.

New Errors

Sent when TrackJS records a never-before-seen error message in your account. You may also customize this, and have it only alert if more than one user is affected. This is handy when a single user is responsible for many one-off errors.

Sent when there is a substantial increase in the frequency of an existing error. That is, the error was previously seen, but it is now occurring more frequently. This is particularly useful for high traffic sites when there are hundreds or thousands of unique error messages.

We record the ranking of the errors in your accounts, you can see this in the Trending Errors Report. The Trending Notification will be sent if an error gains more than 10 places or if a new error is in the top 10 most common errors on your site. In order to keep noise to a minimum, we require an error to be seen a minimum of 10 times before an alert is sent.

Error Rate Increase

Sent when the overall error rate for an application increases 20% above the previous high. We look back several days to ensure it’s not just a cyclical traffic increase. Please note that if your incoming error rate is high enough to cause throttling, the error rate increase alerts may also be affected.
