2. Choose the prospects for whom you'd like to change the email sender. You can use the Step -> In progress filter as well,
3. Select the filtered group and click to Actions -> Change email sender
4. Then, select the new email address and schedule messages!
That's it - new email channel will be added to this campaign!
