2004–2010: Transition and the Rise of Gmail
Gmail (Google)
In 2004, Google launched Gmail, a service that revolutionized webmail with features like large storage, powerful search, and a clean interface. Initially invitation‑only, Gmail quickly attracted tens of millions of users and became a top choice for personal and professional accounts worldwide.

Gmail’s rise marked a turning point: users began to migrate from older services like Hotmail and Yahoo Mail to Gmail’s modern platform, ultimately shifting the balance of email popularity.
2010–2020: Gmail Dominance and Expanded Options
Gmail’s Global Growth
By the 2010s, Gmail became the most popular email provider worldwide, thanks to its integration with Google’s ecosystem (Android devices, Calendar, Drive, and Search). By the mid‑2010s, email usage skyrocketed—including Gmail’s user base.
Outlook.com / Hotmail Evolution
Microsoft transitioned from Hotmail to Outlook.com, consolidating legacy accounts and growing its user base into the business and personal space. This helped Microsoft retain relevance, though Outlook’s share remained far below Gmail’s lead.
Yahoo! Mail Continued Usage
Yahoo Mail remained a well‑known provider despite losing ground in active users relative to Gmail and mobile client growth.
2021–2026: Mobile First and Market Share Shifts
Gmail as the Leading Email Service
By the early 2020s, Gmail remained the most popular email provider, with over 1.8 billion user accounts worldwide.
Apple iCloud / Apple Mail Growth
The Apple Mail ecosystem—tied to iOS, macOS, and Apple devices—became extremely widespread, capturing a significant portion of email client usage globally. In 2024–2025 data, Apple Mail frequently ranked as the top client by market share due to default settings on iPhones and Macs.
Outlook and Yahoo Mail Today
Microsoft Outlook (including Outlook.com and legacy Hotmail accounts) and Yahoo Mail continued to hold notable user bases, though both trailed far behind Gmail and Apple.
A snapshot of popular email providers in recent years shows the mix of usage share across platforms:
-
Apple Mail often holds over 50% of email client market share.
-
Gmail typically ranks second with about 30% of global usage share.
-
Outlook and Yahoo Mail follow with smaller shares (roughly 4% and 2–3% respectively).
Additionally, privacy‑focused providers like Proton Mail have grown interest among niche users, with millions of accounts and tens of millions of users globally as privacy concerns rise.
