What will happen if a campaign shares the same contact list with an already running campaign?

When a campaign shares the same contact list with another campaign that is already running, the functionality of the system prevents both campaigns from operating concurrently on the same contact list. This is to ensure that contacts are not being contacted multiple times, which could lead to confusion or a poor customer experience. By not allowing the new campaign to run, the integrity of the existing campaign's contact strategy is preserved.

The system is designed to manage potential contact overlaps effectively, preventing any negative impacts that could arise from multiple campaigns reaching out to the same individual at the same time. This approach helps maintain compliance with contacting regulations and best practices in outreach strategy. Thus, the campaign sharing the contact list will simply not run as long as the other campaign is active.
