Thank you for reaching out to the Community regarding Archive. While the original Archive setup has been removed, a new Archive feature has been implemented and is available in your account. Instead of a landing page for the archived links we provide you with HTML code you can use to embed up to 50 archived e-mails on your site.
Additionally, we provide you with short URL links for all of your sent e-mails. These links could then be taken and incorporated into a page on your website.
I hope this information helps but I will also pass along your concern and feedback to our product teams.
