Contacts, lists & imports

Add people, group them into lists, and import files without creating duplicates.

ColdMerge stores each person once as a contact. A list groups contacts for a campaign. An import records what one uploaded file changed.

An email address identifies one contact inside your Organization. Importing the same address again updates that contact. It does not create a second copy.

A contact can belong to several lists. Removing a contact from one list does not delete the contact or remove them from other lists.

Before adding people to an existing list, check whether a live campaign targets it. Campaigns keep enrolling new list members by default.
