If you need to make an adjustment to the design being sent in an automated campaign you can do so quickly and easily.
Step 1
Head to the specific active automated campaign that you would like to change the design on.
Step 2
You can only edit the design of automated campaigns that have been stopped. Here's a specific article on how you can stop an active automated campaign.
Step 3
Now that your automated campaign is stopped you'll see a new button that will allow you to edit the design of that campaign. Click the "Edit Design" button.
Step 4
On the next page you'll want to choose which new/updated design you'd like to use for this campaign. Once you've done that click update and confirm your choice.
Step 5
Once you've switched out the design you'll just need to restart your campaign.
