To assign groups to Campaigns, navigate to the Sendoso dashboard, and select the Team Settings link under the menu icon in the top-right corner of the app.
Locate the row of the group you'd like to edit then click the three dots to the right and select Manage Campaigns.
On the left side of the next screen, you'll see all of the Campaigns that are available to add. Click the + sign on the Campaigns you'd like that group to have access to.
On the right side, you'll see all of the Campaigns that the group already has access to. Click the - sign to remove access.
Click Done and that group will have access to the Campaigns you selected!
Keep in mind that you can assign Campaigns to specific groups when you create a Campaign.
