Is there a Joomla ACYM Archive Module available?
Currently there is no such module avalable for v7. If you want to display an archive you can setup a menu item for that.
Please feel free to add a feature request for the modulke on our feature request pag: https://www.acymailing.com/feature-requests/. Other users can upvote ideas, so the devs can see what the most wanted ones are.
A module would be very helpful in organising our archive into our various newsletters and bulletins.
You can achieve a structure by creating different Acymailing Archive menu (sub) items. For each you can select which newsletters you want to show.
