Bulk Updating
KarmaCRM gives you the power to edit 5, 10, or even 100 list items at a time. To bulk edit, check the box on the far left just above your list. This will select all items on the page. If you’d like to select all items including those beyond the page, select “Select all” below the action menu. From here, you can use the action menu to edit all of the items at once. Bulk update applies to the items in the list after your filters - be sure to clear your filters if you want to work with your full list.
You can bulk update any list in karmaCRM, not just the contacts list.
