Okzest

OKZest provides marketers and developers with tools to create personalized images at scale for email and other marketing channels. Marketers can design templates using a drag-and-drop editor that supports dynamic text and images, while developers can use a RESTful API for programmatic image generation. The platform is designed to work inside existing email service providers by returning a single image URL that includes merge tags, enabling personalized visuals without changing existing workflows.

OKZest emphasizes real-time personalization—images update when opened so content stays current—and team collaboration through workspaces, roles, and shared asset libraries. The product includes analytics to track image opens, clicks, and engagement, and supports both no-code and developer-focused integration options.
