Claritas Launches Live Optimization for Acquisition Email Campaigns

Claritas has introduced a product that adjusts audience targeting and subject lines while acquisition email campaigns are still running. It uses holdout groups and attribution modeling to test whether those mid-campaign changes actually produce lift. The announcement offers few details beyond this description.

Why it matters: Marketers running acquisition email can evaluate whether in-flight optimization with holdout-based measurement is worth adopting over traditional A/B testing.
