The Imejis alternative
with merge tags, open-time images, and ESP drop-in URLs

OKZest vs Imejis: the Imejis alternative built for email and agencies

Imejis.io is a template-based image generation platform aimed at social, e-commerce banners, and marketing graphics. Teams design templates, then generate images via REST API, Zapier/Sheets-style automations, or AI agents over MCP (Claude, ChatGPT, Cursor).

OKZest is an Imejis alternative for marketing agencies and email marketers who need personalized images inside emails at open. OKZest personalizes with ESP merge tags, works across Mailchimp, Klaviyo, and ActiveCampaign, and supports open-time / dynamic image URLs - so each recipient sees their data when they open, and creatives can still update after send. Automation is available via REST API (and MCP on OKZest's side too), but most email campaigns are a single drop-in image URL - not a render-then-attach workflow.

Where Imejis optimizes for API/agent design automation and multi-channel graphic production, OKZest optimizes for ESP drop-in personalization at email scale: full visual editor, fallback text, live website screenshots as layers, team collaboration, and Client read-only roles for agencies. Enterprise scales to higher volumes with unlimited seats, billed per image served.

Pricing is built to try before you scale. OKZest's free plan includes 500 free images in total, each with a small "Made with OKZest" badge, and no credit card is needed. Imejis' public free tier is geared to API renders (~100/month on the public site).

Choose Imejis if your main need is social/ecom banners and AI-agent/API design automation. Choose OKZest if email personalization, merge tags, open-time URLs, agency team/client roles, and a generous free plan are the priority.

Switch from Imejis to OKZest in 4 steps

Moving from Imejis to OKZest for email personalization is usually a simplification, not a rebuild.

1. Recreate key email templates in OKZest's visual editor (or start from a ready-made design).
2. Map the same merge fields your ESP already uses (first name, company, offer, and so on).
3. Replace static/API-rendered image assets with the OKZest dynamic image URL in Mailchimp, Klaviyo, ActiveCampaign or your ESP.
4. Send a test and confirm open-time personalization in Gmail and Outlook.

Most teams can validate a like-for-like email campaign on the free plan before cutting over production sends.
