Clerk is built around a powerful API that offers many different ways to display results to customers. These are called Product Logics and offer various functionalities suited to different use cases.
This article explains the available logics for Email and how they work.
The names of these Product Logics match what you see in the my.clerk.io backend when using Content. Each of them has a matching Endpoint in Clerk’s API, which you can inspect in our developer docs using the links provided below.
Best Sellers #
Endpoint: recommendations/popular
Displays the most popular products in your store, specifically those that have been included in the most orders over an extended period. The quantity of the same product in each order doesn’t impact this ranking. It generally remains the same for longer periods as long as you maintain the same products in stock.
Hot Products #
Endpoint: recommendations/trending
Highlights items that have had a recent increase in sales. There’s no fixed timeframe - instead, it’s dynamically calculated based on changes in product sales. For example, if a product typically sells three times a week but suddenly sells 20 times in two days, it’s identified as trending.
Newest Products #
Endpoint: recommendations/new
Shows items that were most recently added to your store, with the latest ones shown first. It requires either the “age” or “created_at” attribute to be available on the products.
Best Sellers In Category #
Endpoint: recommendations/category/popular
Displays the most popular products within a specific category.
Hot Product In Category #
Endpoint: recommendation/category/trending
Highlights products that have recently seen an increase in sales within a specific category.
Newest Products In Category #
Endpoint: recommendations/category/new
Displays the latest products added to a specific category, sorted by the newest items first. This requires either the “age” or “created_at” attribute to be present on products.
Best Alternative Products #
Endpoint: recommendations/substituting
Shows the closest similar items to the product being viewed, sorted by popularity. It compares products based on available attributes such as name, brand, category, price, and other relevant data.
Fallbacks #
If an unknown product ID is provided, Visitor Recommendations are shown. If the visitor is unknown, Best Sellers are shown.
Best Cross-Sell Products #
Endpoint: recommendations/complementary
Displays items most likely to be bought with the product being viewed. It considers products that are commonly bought together and those that are likely to complement each other, such as a belt with pants.
It does this by analyzing typical buying patterns to display suitable recommendations, even for products that have yet to be bought together.
E.g. if it’s normal to buy a pair of footbal boots and shinguards in the same brand and color, Clerk will prioritise these pairs for all brands and colors even if they have not sold together yet.
Fallbacks #
If an unknown product ID is provided, Visitor Recommendations are shown. If the visitor is unknown, Best Sellers are shown.
Most Sold With #
Endpoint: recommendations/most_sold_with
Identifies products that have been frequently purchased alongside any given product or set of products. This logic is simpler than Best Cross-Sell Products, as it only counts items that have been sold with the specified product(s), without predicting anything.
Recommendations Based On Keywords #
Endpoint: recommendations/keywords
Displays products that match a specific keyword or phrase, sorted by their sales performance.
Specific Products #
Does not have an endpoint as it is exclusive to my.clerk.io.
Displays exactly the products specified. If at any point the Number of products is higher than the selected product, the results will be supplemented with Best Sellers.
This also happens if some selected products are removed from Clerk, like when they go out of stock.
Visitor Recommendations #
Endpoint: recommendations/visitor/complementary
Shows products that a visitor is most likely to buy based on their recent browsing. It combines cross-sell and alternative recommendations to find the best matches for each visitor.

If the visitor is unknown, Best Sellers are shown.
