As you very well know, email isn’t dead. It’s just more competitive than ever.

In 2025, email remains the most effective channel for delivering the highest ROI in digital marketing–but only for marketers who adapt to evolving audience behavior, emerging AI tools, and smarter segmentation. 

Whether you’re seeing declining engagement or trying to reach new buyers outside your CRM, these statistics—and the actions that follow—can guide you toward stronger results.

Discover the most recent email marketing statistics data from HubSpot, Statista, and others, where you’ll find tactical takeaways and how ViB Emails help fill in the gaps. Let’s get started!
