Based on the available knowledge sources, there is currently no built-in flag or command in Elementary Data to force resend Slack alerts that have already been sent, without rerunning the tests. Once an alert is sent, it is marked as sent in the database, and Elementary will not resend it unless the underlying test is rerun and fails again. This is confirmed by support staff: > "Unfortunately, no, just by running the tests again. The alerts being sent depend on the status fields (alert_sent, suppression_status, and sent_at), and after sending we mark them as sent." [Slack: Is there a flag to resend latest alerts?](https://slack.com/archives/C02CTC89LAX/p1694416658536899) If you want to see changes in your Slack alert configuration, you will need to rerun your dbt tests to generate new alerts. There is no documented way to "force" resend already-sent alerts for testing purposes.
