 ## Successful delivery rate alerts
 
 You can create an alert that notifies you when the volume of events successfully received by your destination 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.

+
+Segment's custom alerts allow you to customize the sensitivity of the trigger that activates an alert so you can more accurately detect event volume fluctuations in your integrations.
+
+> info "Public beta"
+> The Monitor hub is in Public Beta. Some functionality may change before it becomes generally available. During the public beta, custom alerts are not located in the Monitor tab. 
+
+You can create alerts for the following product areas: 
+- [Sources](#source-volume-alert)
+- [Destinations](#successful-delivery-rate-alert)
+- [Reverse ETL](#mapping-level-successful-delivery-rate-fluctuations)
+- [Twilio Engage](#activation-event-health-spikes-or-drops)
+
+## Source volume alert
+You can create an alert that notifies you when the volume of events received by your source in the last 24 hours changes beyond a percentage you set. For example, if you set a change percentage of 4% and your source received 100 events over the first 24 hours, Segment would notify you the following day if your source ingested fewer than 96 or more than 104 events.
+
+To receive a source volume alert in a Slack channel, you must first create a Slack webhook. For more information about Slack webhooks, see the [Sending messages using incoming webhooks](https://api.slack.com/messaging/webhooks){:target="_blank”} documentation.

+## Activation event health spikes or drops
+
+You can create an Activation event health spikes or drops alert that notifies you when events sent from your audience to a downstream destination have failures to a destination above a certain threshold. For example, if you set a change percentage of 4% and your destination received 100 events from your Audience over the first 24 hours, Segment would notify you the following day if your destination ingested fewer than 96 or more than 104 events.

 - **Default alerts**: Alerts that have a preset threshold and are often used to detect changes users make to the integrations in your workspace. For example, a _Source created_ alert is a default alert. 
 - **Custom alerts**: Alerts that allow you to customize the sensitivity of the trigger that activates an alert so you can more accurately detect event volume fluctuations in your sources and destinations. For example, a _Source volume fluctuation_ alert would be a custom alert, as you could select a percentage of fluctuation that would work for your business needs.
