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:

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 small 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.

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: AWeber, Instantly, Klaviyo, Mailchimp, MailerLite, SendFox, Smartlead, UChat, and Zoho.

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.

Recipient screenshot capture lets you embed a live screenshot of each recipient's own website directly into a personalized image. For example, you can send a cold email that shows the prospect's homepage inside a banner - making it immediately eye-catching and highly relevant to them.

As many as you like - there's no limit on the number of active designs across any plan.

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.

You're only charged for images that are actually viewed. If you send 10,000 emails but only 2,000 are opened that month, only 2,000 images count against your plan. If you exceed your plan's limit, you can upgrade or purchase additional credits - purchased credits never expire and carry over to future months. See the pricing page for full details.
