I have a site where certain Managers need to edit emails to their employees. But I don't want them to have access to config, other campaigns, etc. I can set up a new Permissions Level in Joomla, but how would I limit access in Acymailing?
This can be done using Advanced permissions in AcyMailing Configuration
Are you sure. ?!?
"...By default every user group which have access to the back-end..."
As far as I understand he asked for "frontend" access...
