You can opt in to receive email, Slack, and in-app alerts about Reverse ETL sync failures and fluctuations in the volume of events successfully delivered to your mapping.

The notification channels that you select for one alert will apply to all alerts in your workspace.

Mapping-level successful delivery rate fluctuations

You can create an alert that notifies you when the volume of events successfully received by your mapping in the last 24 hours falls below a percentage you set. For example, if you set a percentage of 99%, Segment notifies you if your destination had a successful delivery rate of 98% or below.

To receive a successful delivery rate fluctuation alert in a Slack channel, you must first create a Slack webhook. For more information about Slack webhooks, see Slack’s Sending messages using incoming webhooks documentation.

To subscribe to alerts for successful delivery fluctuations at the mapping level:

1. Navigate to your intended mapping and select the Alerts tab.
2. Click Create alert.
3. Set an alert threshold, or the percentage of successfully delivered events that would prompt an alert.
4. Select one or more of the following notification channels:
   • Email: Enter an email address or alias that should receive alerts.
   • Slack notification: Enter a Webhook URL and a Slack channel name to receive alerts in a Slack channel.
   • In-app notifications: Select this to receive notifications in the Segment app. To view your notifications, select the bell next to your user icon in the Segment app.
5. Toggle the Enable alert setting on and click Create.

To edit or disable your alert, navigate to your mapping’s Alerts tab and select the Actions menu for the alert you’d like to edit.
