you can create one template in dreamweaver or in the text editor right in cs-cart, buy one from some sites that offer that kind of service or even copy one over from Mailchimp if you are a member.
What you have do to is create a new template and copy over the html you just made/bought and save it by a distinctive name.
Then each time you are going to create a new newsletter you will find it in the list above the text editor.
As for the thing about exporting emails, things are a bit limited. But you can export them to mailchimp via a mod and then either send your emails from over there or manage them as you wish. Mailchimp is very powerful tool for newsletters and for small volumes is free! ([url=“http://mailchimp.com/”]http://mailchimp.com/[/url])
Just one clarifiation regarding our mailchimp addon, it is an addon, not a mod. I.e. there are no modified files that are distributed by cs-cart. Hence no upgrade conflicts. Everything is done through the addon and/or via hooks from the core code/templates.
