# OKZest > OKZest generates personalized images at scale. You build one image template, add merge tags for the parts that change, and OKZest renders a unique image for each recipient at the moment it is viewed - in emails, newsletters, chatbots, certificates, social media and websites. Key facts: - Images are served as a standard HTML `` tag, so OKZest works with any platform that renders HTML images. No plugin or integration is required. - Personalization happens at render time, not send time. Because the image is generated when the email app requests it, the design can be updated after sending, until the recipient's email app has loaded the image. - Merge tags can be written in any format to match the sending platform - `*[FNAME]*` for Mailchimp, `{{first_name}}` for others. A fallback value can be set for missing data. - Personalizable elements: dynamic text, foreground images, background images, and automatic screenshots of a recipient's website. - Data can come from any source that can pass a URL query parameter - an email service provider, CRM, database or API. - Free plan: 2,500 generated images per month, permanently, with no credit card and no time limit. Free-plan images carry a watermark. - Billing is per image served, not per email sent. An image counts when an email app requests it. Apple Mail loads images before the email is opened, so the count is usually close to the opens an email platform reports. The two numbers can differ. - Image generation adds under half a second to image download time. - Two ways to use it: a no-code visual design tool, and a REST API with MCP server support. - Team accounts support role-based access for Administrators, Designers, Finance contacts and Clients, with read-only client review access. - Confirmed email service providers include AWeber, Instantly, Klaviyo, Mailchimp, MailerLite, SendFox, Smartlead, UChat and Zoho. - Security: encryption in transit and at rest, two-factor authentication available on all accounts. - OKZest is a UK-based company. ## Core pages - [Homepage](https://okzest.com/): What OKZest does, with a live interactive demo that renders a personalized image as you type. - [Pricing](https://okzest.com/pricing): Current plans (Micro, Starter, Professional, Enterprise), image allowances and team seat counts.
