Getting started

OKZest is a platform that lets businesses generate personalized images dynamically - embedding each recipient's name, company, website screenshot, or any other data directly into an image in real-time. It's used across email marketing, newsletters, social media, websites, chatbots, certificates, and more.

Higher engagement: Personalized images capture attention and have been shown to significantly increase click-through rates compared to generic images.

Time savings: OKZest automates the creation of thousands of unique images - no manual editing or design work needed per recipient.

Consistent branding: Every image is generated from your template, so your brand design stays consistent across every touchpoint.

You build an image template in OKZest's editor, adding merge tags wherever you want personalized content - text, foreground images, or background images. OKZest generates the image the moment a recipient views it, injecting their data in real-time.

The image embeds into your email or web page as a standard <img> tag, so it works with any platform that supports HTML images:

<img src="loadImageUrl?c=ABC123&i=XYZ456&name=*[FNAME]*" />

Merge tags can be in any format to match your email service provider - e.g. *[FNAME]* for Mailchimp, {{first_name}} for others. You can also set a default fallback value for when a variable is missing.

Sign up for a free account - no credit card needed. You'll get 2,500 generated images per month to try the service. Once you're in, create a design, add your merge tags, copy the image URL, and drop it into your email or webpage. See our documentation for a step-by-step guide.

Yes - the free plan includes 2,500 generated images per month, forever. No time limit, no credit card required. Free plan images include a watermark to indicate they're for testing. When you're ready to go live, upgrade to a paid plan to remove the watermark and increase your image limit.

Yes - this video shows a full end-to-end walkthrough: building an image template, adding merge tags, and using the image in a Mailchimp email campaign.

Features

Anywhere that renders an HTML <img> tag works with OKZest. That includes: email campaigns, newsletters, blogs, websites, chatbots, CRM platforms, certificates, social media posts, Shopify stores, WordPress, Microsoft SharePoint, and SAP Portal.

If your platform supports dynamic images or merge tags in <img> src attributes, OKZest will work with it.

Because merge tags can be entered in any format, OKZest works with virtually any platform that supports dynamic images. Tested and confirmed providers include: Weber, Instantly, Klaviyo, Mailchimp, MailerLite, SendFox, Smartlead, UChat and Zoho.

Don't see yours listed? It almost certainly works - contact us to confirm.

OKZest supports both static content and dynamic merge tags. Dynamic data can come from any source - your email service provider, a CRM, a database, an API, or even URL parameters. Anything your sending platform can pass as a query parameter can be merged into the image in real-time.

Yes. OKZest includes team functionality with role-based access - Administrators, Designers, Finance contacts, and Clients each have appropriate permissions. Clients can be given read-only access to designs so they can review and give feedback without being able to edit.

Performance & security

Images are generated the moment a recipient's email client or browser requests them. Generation adds less than half a second to the overall download time - fast enough that recipients won't notice any delay.

OKZest runs on cloud infrastructure built to generate millions of personalized images per day. Whether you're sending hundreds or millions of emails, the platform handles it without any configuration changes on your end.

OKZest uses industry-standard encryption for all data in transit and at rest. We follow strict privacy policies and never share user data with third parties. Two-Factor Authentication (2FA) is available for all accounts to protect against unauthorized access.
