 ### Model-level volume spike alerts
 
 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 set percentage. 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.

 ### 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](https://api.slack.com/messaging/webhooks){:target="_blank”} documentation.
