Hi,
I guess you want to show the newsletter inside your website's template?
By default Acymailing displays the online version as you have experienced. This is the same way as other major ESP's, ilke Mailchimp for example,display the online version of the email. Within Acymailing there's nothing you can change about that.
I believe you are using Joomla? In that case you can try this workaround with some extra lines in your .htaccess.
RewriteEngine On
RewriteCond %{REQUEST_URI} ^/component/acym/archive/ [NC]
RewriteCond %{QUERY_STRING} ^userid(.*)$
RewriteCond %{QUERY_STRING} !&Itemid=0000
RewriteRule ^(.*)$ /$1?%{QUERY_STRING}&Itemid=0000 [QSD,R=302,L]
Replace 0000 with the id of the menu item you want to display the newsletter in. (You need to change both lines that contain the Itemid)
