Thank you for reaching out to the Community! At this time, the way you are creating and sending your Autoresponder emails is the correct way. When you create your new Autoresponder, you are able to copy existing emails from past campaigns so you are not having to recreate the email templates as well.
I understand this is not ideal for you, and I do apologize we don't have an easier way of resetting the Autoresponder emails. I will certainly submit your feedback to our developers regarding this issue.
In the meantime, if you have any further questions please feel free to reach out to us here. We are always happy to assist you in any way we can!
Our "Email Marketing Mastery Series" webinar this week is covering Email Automation!
I think you will find this webinar, along with the others we offer helpful!
