Signals vs. segments: why intent beats a filter every time

Segments describe who someone was. Signals describe what they're about to do. Here's why that difference is everything.

Signals

For twenty years, we've filtered lists. Purchased in the last 30 days. Opened three emails. Lives in New York. It got us this far, but it hit a ceiling.

The problem with filters

Filters describe history. They don't tell you why someone acted or what they'll do next. A customer who bought last month might be a loyal repeat, or already gone.

Signals close the loop

  • Interested: showing curiosity, not yet ready to buy
  • High intent: actively evaluating, needs a nudge
  • VIP: high LTV, deserves concierge attention
  • Churn risk: dormant behavior after prior engagement

When you build campaigns around signals instead of filters, you speak to who a customer is right now, not who they were the day you tagged them.
