Use case: Great for simple alerts to your inbox or a team distribution list.

Customization: You can include breach details in the subject or body of the email, using data from the New breach node.

2. Slack Node

What it does: Sends a message to a Slack channel or user.

Use case: Perfect for real-time alerts to your team in Slack.

Customization: You can post breach details directly in a channel or DM. You can also format the message (bold, code blocks, etc.).

3. Microsoft Teams Node
