Email continues to operate at massive scale. Current estimates put the global email user base at about 4.59 billion people in 2025, which means more than half the world uses email in some form.
Roughly 376.4 billion emails were sent and received per day in 2025. That number is projected to rise further in 2026 and 2027, showing that email is still growing even after decades of use.
Email remains foundational because it supports personal accounts, business communication, account logins, receipts, marketing, and digital identity across the web. A stronger 2026 stats page should focus on this scale and persistence rather than treating email as an aging legacy channel.
