Will the Diocese or Archdiocese be able to contact our parishioners?

Some dioceses / archdioceses /  are using Flocknote in collaboration with all of their respective churches (such as the Archdiocese of New York).

If you're using Flocknote as part of that arrangement, then your arch/diocese or parent organization will be able to send your parishioners emails and texts. However, your members can unsubscribe from messages sent by the arch/diocese or parent organization at any time while continuing to receive info from your network. They can also unsubscribe from your network at any time.
