Top HubSpot alternatives in 2026 (pros, cons, pricing)
Blog post from Knock
As companies outgrow HubSpot due to scaling costs, limited control, or the need for additional messaging channels, several alternatives have become popular. HubSpot remains a strong choice for small, traditional marketing teams focusing on email marketing and CRM, but many technical teams now prefer specialized tools that offer greater control and cross-channel messaging capabilities. Alternatives like Knock, Customer.io, Braze, Iterable, ActiveCampaign, Klaviyo, and Sendbird provide various strengths, from programmable messaging infrastructure and behavioral automation to real-time engagement and ecommerce integration. Knock, for example, is well-suited for product-led teams needing cross-channel messaging infrastructure, while Braze is ideal for consumer apps requiring large-scale engagement. These alternatives address HubSpot's limitations, such as developer flexibility, event-driven messaging, pricing structure, and cross-functional collaboration. Each platform offers unique features that cater to different team needs, such as Knock's advanced workflow functions and Customer.io's behavioral triggers, allowing teams to choose based on their specific requirements and goals.
