ConvertKit comes with 3 templates: Text Only, Classic, and Modern. You can set any template as your default, including a custom template.
In this article, we'll show you how to duplicate these templates, in order to make edits as needed, and use them for what you need!
Go to your Account Page > Email Template.
Open the 'Text Only' template (or your preferred ConvertKit template) and copy all the text.
Create a new template, and paste your copied text into the box.
Now, you can make edits to your template while using our default templates as framework!
