Email Marketing in 2025: 7 Data-Backed Benefits That Skyrocket ROI
Quick answer: Email marketing now delivers $36–$45 per $1 spent, reaches 4.6 billion users, and converts 24 % better than social media. Below you’ll learn the seven benefits that make it the highest-ROI channel in 2025.
Why Email Marketing Still Crushes Every Other Channel in 2025
Despite TikTok, AI search, and every shiny new tactic, email remains the workhorse of digital marketing. The numbers are almost absurd:
- 4.6 billion active email accounts—forecast to hit 4.8 billion by 2027 (Statista, 2025).
- 99 % of users check email daily; 61 % check it before social media each morning (Adobe Email Usage Study, 2025).
- Retailers rate email as the #1 channel for customer retention—ahead of SMS, push, and loyalty apps combined (Litmus State of Email, 2025).
“Email is the only marketing asset you truly own. Algorithms can tank your reach on social overnight, but your list is yours forever.” — Neil Patel
