The Power of Primary Inbox Placement: Key Statistics for E-commerce Success
1. Email marketing delivers $36-$42 ROI per $1 spent
Email remains the highest-performing marketing channel, generating $36-$42 in returns for every dollar invested. This exceptional ROI depends entirely on whether emails reach the Primary inbox, where visibility and engagement rates are significantly higher than the Promotions tab.
2. Global email users reached 4.83 billion in 2025
The addressable audience for email marketing has never been larger, with 4.83 billion users actively using email in 2025. This number will climb to 5.61 billion by 2030, making inbox placement optimization increasingly valuable for brands competing for attention.
3. Daily email volume hit 392 billion in 2025
With 392 billion emails sent daily and projections reaching 523 billion by 2030, standing out in crowded inboxes requires more than compelling copy. Primary inbox placement gives e-commerce brands a significant advantage over competitors relegated to the Promotions folder.
4. Average email open rate across industries is 42.35%
The industry-wide open rate of 42.35% represents a benchmark that many e-commerce brands struggle to reach. Brands landing in Gmail's Promotions tab typically see open rates 40-60% below this average, highlighting the importance of inbox placement optimization.

The email marketing industry is projected to grow from $12.33 billion in 2024 to $17.9 billion by 2027. This growth reflects increasing investment in deliverability solutions and AI-powered optimization tools that maximize channel performance.
