OKZest
Personalized image campaigns for marketing agencies
OKZest is a platform for generating personalized images dynamically, embedding each recipient's name, company, website screenshot, or other data directly into an image in real time. It is used across email marketing, newsletters, social media, websites, chatbots, certificates, and more. Images are generated when requested and delivered as a standard HTML img tag, so they can be placed in any platform that renders dynamic images.
Two main ways to use it: a no-code visual design tool with a real-time personalization preview and pre-built templates, and a REST API with full documentation for programmatic image generation. Features include dynamic text, dynamic image layers, screenshot-based visuals, fallback values for missing variables, and team functionality with role-based access. Integrations cover MCP support for AI assistants such as Claude, ChatGPT, and Copilot, plus Zapier for no-code automation. Compatible email service providers include Mailchimp, Klaviyo, AWeber, Instantly, MailerLite, SendFox, Smartlead, UChat, and Zoho.
OKZest is aimed at marketers, designers, account managers, developers, and teams across email marketing, sales, eCommerce, real estate, events, and coaching. It is packaged with a free plan offering watermarked images each month with no time limit, and paid plans (Micro, Starter, Professional, Enterprise) that remove the watermark and vary by monthly image allowance and team member count. Billing is monthly or yearly, and usage is based on images actually generated when opened.
