Justuno

Justuno combines email and SMS with a built-in popup and personalization engine to capture visitor data at the moment of interest. The platform powers abandoned cart recovery, giveaway campaigns, and exit-intent messages all in one dashboard. It also includes basic website personalization to show targeted content based on visitor behavior.

Best for stores wanting email capture, SMS, and popups without juggling multiple tools. Compared to email-only apps, Justuno adds the popup layer that can significantly boost list growth before automation even starts.
