How do signal-based campaigns add new leads automatically?

Last updated: June 12, 2026

Customer Question: Why did my campaign start with a certain number of leads, but now the audience size keeps increasing?

Short Answer: This is expected behavior for Signals-based campaigns. Signals campaigns continuously monitor for trigger events that match your targeting criteria. When new qualifying events occur, additional leads can be automatically added to the campaign audience.

This is expected behavior for Signals campaigns.

Rather than working from a fixed list of leads, Artisan continuously monitors for the signal you've selected, such as new leadership hires, funding events, or other qualifying triggers.

When new companies or prospects match your targeting criteria and trigger an event, they are automatically added to the campaign audience. As a result, the audience size can grow over time, even if the campaign initially had fewer leads.

One of the key benefits of Signals campaigns is that they help you reach prospects as new opportunities emerge, rather than relying on a static lead list.

If you'd like to limit audience growth, you can narrow your targeting criteria or pause the campaign.
