 | `git-config-name`  | Allows you to customize the name that is attached to the git config which is used when pushing the deployment commits. If this is not included it will use the name in the GitHub context, followed by the name of the action.                                                                                                                                               | `with` | **No**   |
-| `git-config-email` | Allows you to customize the email that is attached to the git config which is used when pushing the deployment commits. If this is not included it will use the email in the GitHub context, followed by a generic noreply GitHub email. You can include an empty string value if you wish to omit this field altogether.                                                    | `with` | **No**   |
+| `git-config-email` | Allows you to customize the email that is attached to the git config which is used when pushing the deployment commits. If this is not included it will use the email in the GitHub context, followed by a generic noreply GitHub email. You can include `<>` for the value if you wish to omit this field altogether and push the commits without an email.                                                    | `with` | **No**   |
 | `repository-name`  | Allows you to specify a different repository path so long as you have permissions to push to it. This should be formatted like so: `JamesIves/github-pages-deploy-action`. You'll need to use a PAT in the `token` input for this configuration option to work properly.                                                                                                     | `with` | **No**   |
 | `target-folder`    | If you'd like to push the contents of the deployment folder into a specific directory on the deployment branch you can specify it here.                                                                                                                                                                                                                                      | `with` | **No**   |
 | `commit-message`   | If you need to customize the commit message for an integration you can do so.                                                                                                                                                                                                                                                                                                | `with` | **No**   |
