Quarticon is a Good Complement to Klaviyo
Klaviyo is an advanced marketing automation system, while Quarticon is a recommendation engine for e-commerce that autonomously manages product offerings for each user individually in store. If you care about anonymous users* you should use both tools.
*You should care about, they are ~95% of your traffic
Native recommendations in Klaviyo require the user to be “known” (registered and logged in or identified as known via cookie) to trigger the personalization algorithm. However, this is not enough, as it applies to 5% of your customers. Quarticon will therefore increase the effectiveness of your emails in Klaviyo and from the website, where 95% of your customers are. Quarticon is not an alternative to Klaviyo but a significant addition to your store and mailings, in areas where using Klaviyo may not be effective enough.

What Are the Main Restrictions in Klaviyo?
Klaviyo is a platform for email marketing and marketing automation. Klaviyo generates recommendations in emails using a system called Product Feeds. This system tracks customer interactions, such as clicks, cart actions, and purchase history, to automatically populate emails with highly personalized proposals.
Klaviyo relies solely on logged-in and recognized users, therefore it is not effective enough as a standalone tool in e-commerce. The percentage of users we can identify is continuously decreasing (due to ad-blocks, 3rd party cookie restrictions, using Firefox, and finally, cookies not accepted by users). This means that a significant majority, as much as 95% of users in e-commerce stores, are anonymous. This is new traffic, e.g., from social media, search engines, AI assistants. These are users with ad-blocks and in incognito modes. Last, but not least, these are those who purchased as guests.
In such a situation, Klaviyo fails as a tool for offer personalization in the store.
AI Models in Klaviyo Can Be Incorrectly Trained
Firstly, training models in Klaviyo is conducted on 5% of users – simplifying, it takes 20 times longer – instead of 1 month – 20 months! Quarticon achieves full operational efficiency in product decision-making after 1 month, Klaviyo after nearly 2 years!
Secondly, training models in Klaviyo on 5% of the population is subject to a huge error. The system learns only part of specific behaviors, which distorts the conclusions drawn. The Quarticon product recommendation engine learns from 100% of the traffic on the site, in emails, and applications, on logged-in and anonymous users.
Additionally, most importantly, Klaviyo is unable to target unknown users at all (let’s recall: 95% of traffic) on the site. If you use the Customer Hub or Customer Agent chat functions in Klaviyo to display recommendations on the site, in the case of anonymous users, because Klaviyo cannot retrieve the profile, the system automatically switches to general suggestions such as “Popular”, “Bestsellers”, or “New Arrivals”. More information in this article: How Recommendations Work in Marketing Automation.
Therefore, adding Quarticon in emails in Klaviyo makes a lot of sense and is a much more recommended solution for product personalization in stores.

Is Quarticon a Good Tool for E-commerce?
Quarticon is a tool that was introduced primarily to serve unknown, anonymous users (95%), and incidentally, without the slightest obstacles, serves known users (i.e., the remaining 5% that Klaviyo also serves).
This means that using Quarticon, anonymous users, who are the majority, will be served with more accurate product suggestions. This means significantly higher conversions and sales, even 3.5x. Therefore, Quarticon is a better tool for e-commerce than Klaviyo!
But there is good news! You don’t have to change the system and move the database. Stay in Klaviyo, add Quarticon components, and your store and your mailings will be much more effective. You can also change the system to a simpler and cheaper one while maintaining the functionality necessary in e-commerce. Details in the FAQ below.
Key Features of Quarticon AI-mails for Klaviyo Service
Automatically create offers featuring new arrivals
Automatically include new arrivals from your store in emails, newsletters, and even notifications sent from your e-commerce platform.

Sending PDF newsletters via email is a relic of the past. PDF offers are sent only because structuring an email, for example, with 30 products embedded in the message, is a very complicated and time-consuming task. But not with Quarticon AI-emails.
Embedding 1 product takes 5 seconds; embedding 30 products takes 5 seconds × 30—and it’s a one-time task.
Cross-sell offers in your email campaigns

Quarticon recommendations vs other solutions simply explained
How do other, common “recommendation frames” in e-commerce platforms work?
The best way to illustrate it is with an example.
You have a clothing store where white T‑shirts for €5 sell best.
A new customer comes in and looks at a dress priced at €100.
The shop assistant approaches her and says, “you should buy this T‑shirt instead.”
Something’s off here, right?
This is how most recommendations available in e-commerce platforms, marketing automation, and CDPs work! That’s why it’s better to choose a specialist.
How do “recommendation frames” in marketing automation and CDPs work?
Marketing automation only remembers a few customers who have bought something before.
In a real‑world example it would look like this:
If the customer is anonymous (comes for the first time, the seller doesn’t recognize them – in e‑commerce that’s an adblock or cleared cookie) it will be like the example above: “you should buy this T‑shirt”.
And such customers make up 95%. 95% of wasted opportunities.
Now the real power of marketing automation: we recognize the customer.
The assistant shouts at the door: “Hello, Ms. Maria” (hurrah! we know the customer).
Maria calmly goes to the dresses and looks at a red dress for €100.
The assistant, a crafty one, remembers that Maria bought trousers a month ago, so she shouts: “Ms. Maria, we have great trousers on sale”.
This is how recommendations in marketing automation and CDPs work. They operate on historical data.
Even for regular customers (5% of all customers) they are unable to recommend the right product.
Only tomorrow will they realize that Maria came for a completely different product than trousers. Tomorrow is already too late.
How does the Quarticon product recommendation engine work?
The Quarticon product recommendation engine adapts in real time, instantly to the recipient’s behavior.
So again, illustratively.
A customer comes into the store and looks at a red dress for €100.
The assistant approaches, greets her, and says there is an interesting model of the same kind of dress.
The customer hesitates, considers it, but takes another dress. However, she puts it back.
The assistant, trained on tens of thousands of cases, suggests one more dress to the customer and hits the mark. The customer buys it.
What did the assistant do? She adapted in real time to the customer’s needs and used the knowledge she built from thousands of other customers about which dresses might appeal to the customer based on what she had viewed so far.
That’s how the Quarticon AI product recommendation engine works.

What is Quarticon AI-mails?
Quarticon AI-mails is a service that provides content personalization in mailings and web push (and beyond) in any marketing automation system. Decisions about product or content selection are made by the Quarticon DE (Decisioning Engine), based on proprietary predictive models (pAI).

Effortless, integration-free, it provides a consistent experience across all communication channels, eliminating 90–95% of the tasks and effort involved in preparing a personalized and up-to-date product offer in emails.

Does Quarticon AI-mails rely on generative artificial intelligence?
No, the system does not use generative artificial intelligence at all (such as ChatGPT, Gemini, Claude, Mistral, etc.). It uses proprietary predictive AI algorithms trained to match product offers and content. Therefore the system will not write your newsletter intro for you. But it will populate it, for example, with products that are tailored to each recipient of the newsletter individually.
Will every email recipient get an individually selected offer?
Yes. The AI-mails service, at a higher package level, allows individual tailoring of the offer to the user based on their previous purchases and on-site behavior and clicks in sent emails. Offer management is handled by the Quarticon decisioning engine / recommendation engine.
Does the product offer in the email refresh in real time?
Exactly! The product offer refreshes in real time and individually for each email recipient. Every time the user opens the email you can be sure the offer in the email content will be up to date. This helps achieve better alignment with each recipient’s current needs and, of course, positively impacts conversions.
Can I change the product offer after sending the email?
Everyone will tell you that’s a silly question and of course not. But not with Quarticon AI-mails! The offer changes dynamically between sending and opening. Top-sellers sold out in the meantime? No problem. The system will select other well-selling and available products.
Do I need a developer to start using Quarticon AI-mails?
No, you do not need a developer to use Quarticon AI-mails. The system does not require any complicated integration with either the sending system or the e‑commerce platform. That’s the beauty of it. Launching Quarticon in your store will take you just a few minutes using the step-by-step instructions in the panel.
Can I get help integrating Quarticon AI-mails in my store?
Yes, our support plan provides full assistance with integration. Quarticon offers a wide knowledge base and 24/7 technical support, making it user friendly.
Can I adapt the product appearance to my email template?
Yes. In the user panel you have access to a so‑called product tile builder. You can create any templates containing photos, prices, product names, or only product names, in a horizontal or vertical layout. At the end you define which template to use and which product display strategy, and a ready snippet for your mailing is generated.
Do I Have to Give Up Klaviyo to Use Quarticon?
No, you do not have to give up Klaviyo marketing automation and move the database to use Quarticon products. However, it may turn out that a simple marketing automation solution, e.g., free Mautic or Brevo combined with Quarticon will be completely sufficient to implement most of the advanced functionalities presented by the Klaviyo system! It’s up to you.
