If you set up an owner and link the owner to a Slack handle, the owner will automatically be tagged in the alert, making it clear to everyone responsible for addressing the alert. Slack handles can be both individuals (e.g., John Doe) or groups (e.g., product-analytics) It’s particularly helpful to associate Slack handles with owners when you have a central alerting channel (e.g., #data-alerts) and a larger data team, as it can otherwise be difficult to know who’s responsible for looking at an alert. The data team is being tagged for an anomaly alert title
