Hi @miciver. If you copied the campaign then yes you can delete the old newsletters from this automation & it won’t effect the previous automation. In your new automation click on the email icon at the top right (next to the active/ inactive switch). This will bring up all emails in the automation & you can choose to delet the ones you don’t need by clicking on the blue arrow on the right.
We’ve recently updated our Automations product and you can now delete automation emails via the “Manage Email” button on the top right corner, next to “View Contacts”.
Here’s a quick demo on how to delete the emails with this new feature update: https://screen.ac/GGudO0Kx.
Please don’t hesitate to reply back out or email us at help@activecampaign.com if you have any further questions.
