Unique records for mass mailing

This module extends the functionality of mass mailing lists to disable duplicate entries in list names and contact emails per list.

This way you will avoid sending the same message more than once to the same contact when selecting a mailing list, and you will avoid conflicts when importing contacts to a list that has a duplicated name.


Before installing this module, you need to:

  • Remove all duplicated list names.
  • Remove all duplicated emails in each list.


To use this module, you need to try to create a duplicated mailing list, or a duplicated email inside one. You will not can.
