This add-on allows you to filter your AcyMailing users by contact category in the automations.
This add-on is available with the Enterprise version.
Filter by category
In Joomla, the contacts have a specific category and you'll be able to filter them using this filter.
The contacts are linked to the AcyMailing users using either their email address or their Joomla user Id (if the contact is linked to a Joomla user).
When using the "Not in" operator, the AcyMailing users that don't have any corresponding Joomla contact will also be selected (they don't have a Joomla contact, thus they are not in the selected category).
