  +
   notify:
     - webhook: "https://webhook.site/82n740x6-168b-5aca-9067-3b410g78c23a"
     - webhook: "https://webhook.site/32raf257-81b6-9067-5aca-78s09m6102b4"
  
positive.code: ```
  {: codeblock-file="pipeline.yml"}
  
  The `email` attribute accepts a single email address as a string. To send notifications to more than one address, add each address as a separate email notification attribute:

    - email: "dev@acmeinc.com"
    - email: "sre@acmeinc.com"
    - email: "qa@acmeinc.com"
  ```
  {: codeblock-file="pipeline.yml"}
