Mailcoach can render a beautiful website for your email list that displays an intro text, a subscription form, and all your past campaigns you sent to that list.
You can enable it in the website settings of your list.
Here's what it looks like for one of our users.
When users click an edition and scroll a bit down, they can see the content of an edition. Here's the content of an old edition of that newsletter. We automatically display the sent date there, so people have an indication of when the content was written.
In the website settings, you can also pick a header image and text, and also choose the base color of your archive. As a nice detail, the form element's value is displayed in the value's color.
Here's how the above website looks using different colors.
