The Potential Reach number represents the total amount of contacts that fall under the Send To filter you’ve selected for your campaign. Depending on the filter type you choose, the number of contacts will vary.
The Potential Reach dynamically updates to show only the contacts that actually meet the criteria you selected, excluding any contacts that do not fit within that filter.
This helps you understand exactly how many contacts your campaign will reach before sending it.
