What are Tribes and Tags?
Tribes and Tags are ways of categorizing your contacts that have particular similarities.
Categorizing your relationships according to Tribes works great for targeted email blasts or for running reports. You might choose categories such as Large Gift Donors or Frequent Donors or Event Volunteers. Then when you filter for one of these Tribes, you get a targeted list.
Just remember that Tribal categories are meant to be of a long-standing, permanent nature.
If you want to implement more incidental groupings, use Tags. You can devise your own in-house categories, so you know what sorts of things are Tag-worthy and which are Tribe-worthy.
