Why Email Still Wins
With 376.4 billion emails sent daily in 2026, you might think email is dead. It's not. It's more competitive, which means strategy matters more than ever.
The key is moving beyond batch-and-blast to intelligent, segmented, automated communication.
> "Marketing automation clearly boosts segmentation efficiency and, as a result, improves message targeting. According to Liana's Marketing Automation 2025 survey, the most common result achieved with marketing automation was more effective targeting and segmentation."
