#### Creating a Campaign
To create a Campaign, click the Create Campaign button.
Provide a unique Campaign name, and click to upload CSV file containing the list of members in the campaign. The upload CSV file must have the following columns:
* *Email*: the members email address
You can optionally provide additional custom columns for reporting. For example:
* *Office*: the site/location of the team member
* *Organization Unit*: the business unit of the team member
### Updating a Campaign
{% hint style="danger" %}
The uploaded list of members *replaces* the current members of the campaign
{% endhint %}
To update the members associated with the campaign, click the “Edit Campaign” button on the Campaign Detail page:
The upload CSV format has the same structure for campaign creations.
In order to facilitate re-upload of a member list generated via “Export” (see Campaign Details below), the following columns in the upload file are ignored:
* Status
* Date Joined
* Extension Version
* Last Seen
