Had an extremely frustrating experience trying to work with an automated series. Our shopify store integrates with an app called Privy which captures emails and serves Abandon Cart emails. When someone signs up to get access to our VIP section they sign up, their email goes through Privy then is added to a list in Constant Contact. When a person is added to the list it sends then a Welcome email 1) The problem is once you set up an automated campaign if you find out a link isn't working, you don't have the option to pause the campaign and go in and edit the email and then reactivate. You have to close the campaign and start all over. This is a real hassle and causes confusion in the dashboard. We have 6 or 7 emails now that had been either deleted or cancelled just for us to get 1 campaign to work. Additionally once you cancel a campaign and start over from scratch you have disrupted all of the links you have already established. In our case we have emails being captured by an app called Privy. It only allows people to sign up 1 time to receive the 10% discount. Each time we needed to retest the automated emails we had to go in and delete the testing email addresses. In the end the automation stopped working and we couldn't figure out if it was a problem in CC or Privy, because CC's automated campaign could not be edited and each time we found a link not working or needed to edit the email we had to start over from scratch. I recommend you either create the option to pause a campaign so you can edit it or create a test mode.
Thanks for all the feedback on this. As Candace mentioned above, we've made improvements that will allow for the editing of an active step to allow you to make changes on the fly. This article goes over the steps if you'd like to see how it works.
