Clerk.io

Clerk.io is an AI platform for online stores that combines on-site search, product recommendations, a shopping chat assistant, audience segmentation and personalized email in one system. Its email product sends campaigns and automated emails in which the AI picks the products each subscriber is most likely to buy next. The company pitches itself as "The AI Agent that makes your E-commerce more profitable" and says Clerk.io "is trained on 15 years of e-commerce data from millions of successful conversions". It is built for web shops, not for newsletters in general: every feature is fed by the store's catalog, orders and shopper behavior. Support hours on the site are given in CET. Clerk.io also says it "works instantly with no learning period", drawing on prior buyer history from the moment a store connects.

What a sender gets

Email. The home page describes the email product this way: "Send emails that are personalized for every subscriber, featuring the products they're most likely to buy next. Clerk.io automatically selects and inserts product recommendations using AI, and updates them dynamically when the email is opened". Because the product blocks are filled at open time, an email sent on Monday and opened on Thursday shows products chosen at the moment it is read. The product menu describes it as "Data-driven emails with personalized campaigns". A recent product update, "Faster image delivery for Email Embeds", shows that Clerk's product blocks can also be embedded in emails built elsewhere. The Magento guide on Clerk's site lists the kinds of automated flows it advises stores to run, such as welcome, cart abandonment, post-purchase and win-back, with triggers based on browsing, cart activity and purchases, and with revenue attribution per flow. Among its e-books is "Avoid the Summer Slump: Email on Autopilot".

Audience. Segmentation is its own product. Clerk.io's AI "uses real behavior and purchase intent to build high-performing segments of your existing customers and leads", and those segments feed both emails and "Lookalike Audiences in Meta and Google Ads". An e-book lists "29+ Creative Use Cases of Clerk.io Audience Segmentation". A customer review on the page calls Audience "our favourite" for the insight it gives into the customer journey.

Search. On the storefront, Clerk.io's search is meant to understand intent "even with typos or vague queries" and to combine behavior, sales data and availability to rank results and remove zero-result pages. Product updates mention sortable facet values, faster indexing, and a feature called Intent Search.

Recommendations. Upsell and cross-sell modules use behavior, orders and the whole catalog to choose products for each shopper, with placements such as exit intent, cart cross-sell banners and "Powerstep" best-seller modules named in the video library. The same engine chooses the products in emails, so the store and the inbox show consistent picks.

Chat. An AI chat assistant, described as a "Generative and predictive AI-powered chatbot", helps shoppers find products and answers questions around the clock: "Help shoppers 24/7, even while your support team sleeps." Updates say the chat can now act on the storefront and recommend products.

Verticals. The site lists focus industries including fashion, apparel and accessories, health and beauty, electronics, home and furniture, sporting goods, pet supplies, baby and toddler, pharmacies, toys and games, and jewelry and watches, and it publishes guides on metrics such as average order value, customer lifetime value, cross-sell attach rate and cart abandonment rate.

Platform. Beneath these products sit a data layer, an AI layer, a merchandising layer and a product layer, plus a customer data platform and customer analytics, according to the platform menu. Developers get documentation, a frontend UI kit, an API reference and a system status page. An assistant called Ask Clerk.io helps users work inside the tool.

Integrations

The home page says Clerk integrates with "20+ major platforms", including Shopify, WooCommerce, Magento and PrestaShop. The FAQ on another Clerk page lists "native, plug-and-play integrations across Shopify, Magento, BigCommerce, WooCommerce, Shopware, PrestaShop, and more, typically going live in days rather than months." The footer adds search apps for Lightspeed and DanDomain, and the site has a page on the implementation choices available.

Pricing and trial

The site links a separate Pricing page and describes the model in plain words: "Clerk.io offers transparent, tier-based pricing with a free trial and fast onboarding", and it calls its onboarding "done-for-you" with "predictable pricing". The navigation offers a free trial and a demo; the demo form says "Get instant access after submitting. No credit card required."

Privacy

Clerk.io says the platform is "entirely cookieless and free from storing customer data", and that "This ensures GDPR compliance". The footer links to a trust center, data processing terms, a privacy policy and a GDPR page.

Results and reviews

The site quotes store results rather than platform statistics. On email specifically, Nils Træholt of Med24 says: "We A/B-tested between our own manually selected products and Clerk's automated email recommendations. Clerk showed a 32% higher click-through rate!" Mikael Hansen, founder of Ugleunger, says Clerk's AI-driven automated email campaigns helped grow the store "without needing to scale our team." Other quoted results include a 0.8-product increase in basket size at Hairlust, €22,000+ in sales from AI Chat at Olympia Sport, a 33% revenue increase at Hygiene System and 25% of sales powered by Clerk.io at Korsør Hvidevarecenter. A live counter showed €2,949,417 in revenue generated for customers that day, and the page claims "Over 500 5-star reviews across platforms" with ratings of 4.7, 4.8 and 4.6 out of 5.

Support

Support runs by phone on (+45) 70 555 100 and by email at support@clerk.io, Monday to Thursday 09:00 to 17:00 CET and Friday 09:00 to 16:30 CET. There is a help center, a knowledge base, webinars (its Black Friday webinars run in several languages, including English and German), e-books, a video library and a partner program. Several reviews mention a dedicated Customer Success Manager and training on request.

Who it suits

Clerk.io suits online stores on Shopify, Magento, WooCommerce, PrestaShop, BigCommerce or Shopware with deep catalogs and repeat buyers, where the products in each email matter more than the design of a newsletter. It is strongest for a shop that also wants on-site search, recommendations and chat from the same vendor, with one AI model behind all of them. A creator, a service business or anyone without a product catalog has little to gain, since the email product is built around recommending products, and a brand wanting SMS will not find it among the channels Clerk.io lists.
