The Verdict
AdRoll is built for ecommerce and dtc brands, with a focus on retargeting and display-ads. Substack targets independent writers and journalists and leads with newsletter and paid-subscriptions.
On pricing, Substack is the clear winner for budget-conscious users — starting at $0/mo compared to $36/mo for AdRoll. That $36/mo difference adds up quickly for growing teams.
Substack has a free plan, which gives it a meaningful edge for individuals and small teams exploring their options. AdRoll requires a paid subscription from day one.
Substack edges out on user ratings (4.4 vs 4). While both are well-regarded, that gap reflects real differences in user satisfaction worth considering.
Feature-wise, Substack offers broader built-in capabilities (7 features vs 6), while AdRoll takes a more focused approach — which can mean a simpler, faster onboarding experience.
Bottom line: Substack has a slight overall edge — but if great retargeting matters most to you, AdRoll may still be the right call.
