The Verdict
AdRoll is built for ecommerce and dtc brands, with a focus on retargeting and display-ads. Customer.io targets saas companies and product marketers and leads with event-triggers and segmentation.
On pricing, AdRoll is the clear winner for budget-conscious users — starting at $36/mo compared to $100/mo for Customer.io. That $64/mo difference adds up quickly for growing teams.
Neither tool offers a free plan, so factor the subscription cost into your decision from the start.
Customer.io edges out on user ratings (4.4 vs 4). While both are well-regarded, that gap reflects real differences in user satisfaction worth considering.
Bottom line: Customer.io has a slight overall edge — but if great retargeting matters most to you, AdRoll may still be the right call.
