Currently, Elementary Data doesn't provide a direct way to customize the default title format of test failure alerts in Slack. Based on the knowledge sources, several users have asked about this feature, but it's not yet implemented. There are some related customization options you can use: 1. Custom descriptions: You can add descriptions to your tests that will appear in the alerts:

yaml tests:   - test_name:       meta:         description: "Your custom description here"

[Alert properties in .yml files](https://docs.elementary-data.com/oss/guides/alerts/alerts-configuration#alerts-distribution) 2. Alert fields: You can control which fields appear in the alert body (though not the title):

yaml models:   - name: my_model_name     meta:       alert_fields: ["description", "owners", "tags", "subscribers"]

[Alert properties in .yml files](https://docs.elementary-data.com/oss/guides/alerts/alerts-configuration#alerts-distribution) 3. Project name: For monitoring summary reports (not individual test alerts), you can use the

--project-name

parameter to customize part of the title, though it will still include "Monitoring summary" in the format. This feature request has been raised by multiple users in the community, and the Elementary team has acknowledged it as something they're considering. If this is important for your use case, you might want to create a GitHub issue to help them prioritize it.

Here are the community discussions where users have raised the issue of customizing Slack alert titles: 1. [Customizing "dbt test alert" string](https://slack.com/archives/C02CTC89LAX/p1691608483808449) - A user asked if there's a way to adjust the "dbt test alert" string in Slack messages, and the Elementary team confirmed it wasn't possible at that time but invited a feature request. 2. [Custom title instead of "Monitoring summary"](https://slack.com/archives/C02CTC89LAX/p1708503721637019) - A user with multiple dbt projects (~40) wanted to customize the title to distinguish which report came from which project.
