Liquid
Safe template language created by Shopify.
Liquid is an open-source template language created by Shopify and used in Shopify themes, Jekyll, and many hosted applications. Its main fit for email is safe user-editable templates, stored templates, and commerce-style dynamic content.
Growth work lives or dies on targeting and measurement. What matters is whether behavioral triggers can be built without engineering time, whether the event stream supports attribution past the open, and whether deliverability holds when broadcast volume shares a reputation with product email.
Against behavior-triggered journeys, broadcasts, and winback campaigns measured on revenue, Liquid covers none of the capabilities this audience leans on (scheduling, event stream, the suppressions API, and multi-tenant support), so it fits only where those needs are genuinely absent.
