In efficy you can do mass-updates but I'm looking for the way to do a mass-delete based on a query. Does anyone know how/where this can be done?
e.g. I would like to delete all deceased contacts at once ;-)
Deleting items is not advised in Efficy, (for histrory, ...) and therefore not possible.
But you can set the contacts to inactive using the mass update.
Inactive items (contacts here) are not listed by default in search and lists.
