How do I add a message to an existing campaign in the Impact Dashboard?
Impact allows you to assign a message to an existing campaign to apply the user targeting rules (as defined for the campaign) to your message. This means that if your campaign audience is “Instructors not active with a tool for 30 days” and you connect a message to this campaign, the message will also be targeted at that audience.
Manage Messages
Click the Manage Messages tab [1].
To associate a message to an existing campaign, locate and click the message you want to use [2].
To create a new message, click the New message button[3].
Edit Message
In the View Message page, click the Edit Message button.
Note: If you are creating a new message, the Edit Message button does not display.

Assign to Campaign

To add a message to an existing campaign, enter the terms in the Filter field [1]. Click the checkbox next to the name for the relevant campaign [2]. You can also select multiple campaigns at the same time.
