Why Email Open Rates Still Matter in 2025

Despite Apple Mail Privacy and tracking limitations, open rate remains a key directional metric when evaluated alongside click-through and conversion data. According to MailerLite, average email open rates across industries are around 42%. For ecommerce specifically, the average campaign open rate is between 31–37%. Automated email flows—like abandoned cart, welcome, and post-purchase—often see 48–65%+ open rates. With Clerk.io, automated newsletters and product-triggered emails consistently reach this top-tier performance.
