Email blasts remain foundational to modern marketing because of their massive reach and unprecedented scale. With billions of users checking email daily and trillions of messages exchanged annually, email blasts give businesses direct access to engaged audiences. Understanding the foundational metrics helps justify investment and align strategy with market realities.
The global email user base continues unprecedented growth, with nearly 4.73 billion users worldwide by 2026, representing nearly 58% of the global population. This scale provides marketers with access to one of the largest addressable audiences in digital communication.
In 2026, an estimated 392.5 billion emails are sent and received globally every day. This staggering volume reflects email's role as the primary communication infrastructure for both personal and business use, dwarfing newer platforms in sheer message volume.
Email marketing consistently outperforms all other digital channels, generating an average return of $36 to $42 for every dollar invested. This 3,600 to 4,200% ROI exceeds paid social, search, and content marketing significantly, making email the highest-performing owned channel.

Open rates and click-through rates are the primary engagement signals for email blasts, though privacy changes from Apple Mail and similar providers have reshaped how marketers interpret these numbers. Modern engagement strategies now prioritize click-based metrics and conversion rates over raw opens, reflecting a shift toward measuring real human interaction rather than automated tracking.
MailerLite analyzed 3.6 million campaigns from 181,000+ accounts, showing a steady increase in opens despite Apple Mail Privacy Protection inflating metrics. This baseline helps marketers contextualize their performance, though marketers must account for MPP's pixel-tracking distortion.
Click-to-open rates have become the gold standard for measuring genuine engagement, reflecting the actual percentage of email openers who take action. This 21% YoY jump suggests marketers are creating more compelling, action-oriented content.
Click-through rates (CTR) measure total clicks divided by deliveries and represent the most accurate engagement signal unaffected by Apple Mail Privacy Protection. Legal industry leads at 4.90%, while politics averages just 0.83%.
The Data and Marketing Association's Email Benchmarking Report 2025 tracked over 442 billion emails across B2B and B2C, showing that open rates continue climbing post-Apple MPP as the industry adjusts to this new baseline for measuring success.
DMA data reveals that unique clicks (customers who clicked at least once) are rising despite massive increases in email volume, signaling that quality segmentation and personalization are driving real engagement improvements.
Higher Logic's 2025-2026 Association Email Benchmark Report analyzed 2 billion emails from 1,500 associations, showing that member-focused organizations achieve consistent engagement when prioritizing relevance and personalization over volume.
