| If you specify a user's email address, you'll receive an email notification when the user performs the specified activity. | |
| You can specify multiple email addresses separated by commas. | |

| Default is $null (Activity alert is triggered for any user) | |
| .PARAMETER EmailCulture | |

| For example, de-DE for German, da-DK for Danish or ja-JP for Japanese. | |
| The default is en-US | |
