The Verdict
Loops is built for saas companies and developers, with a focus on event-triggers and email-editor. 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 $49/mo for Loops. That $49/mo difference adds up quickly for growing teams.
Both offer free plans, so you can test each with your real workflow before committing to a subscription.
Feature-wise, Substack offers broader built-in capabilities (7 features vs 6), while Loops takes a more focused approach — which can mean a simpler, faster onboarding experience.
