Industrialize and personalize your marketing emails on a 1:1 scale
In an ecosystem where every interaction can nurture or harm the relationship between a brand and its customer, email marketing is more than ever a decisive point of contact.
But how can you make a difference and capture attention from consumers who are increasingly volatile, demanding and over-solicited (376.4 billion emails sent and received daily in 2025 according to Statista)?
Today, your customers expect more than just a first name in the subject line. They demand relevant, real-time personalized content that adapts to their context, their desires, their needs... and that right now!
To achieve this, industrializing production while personalizing at scale has become imperative. It is therefore necessary to find a balance between technical rigor, graphic consistency and marketing agility.
In this article, discover how to combine modular design systems and 1:1 real-time content to streamline your email production process while offering a unique experience to each of your customers.

Scale 1:1 Content Creation at Scale
Reelevant's promise? Making 1:1 personalization at scale possible without multiplying manual variants. Instead of producing X variations of the same email to cover different use cases or segments, marketing teams design a single structured and templated email in Dartagnan, which Reelevant dynamically generates with the right content at the right time, for each person. This template + hyper-personalization solution logic allows to move from a segment approach to a person approach, while dividing production time by 3 to 5 as observed in client projects.
Concretely, companies like Carrefour, Decathlon or L'Oréal use Reelevant to hyper-personalize their email communications using all data at their disposal while maintaining centralized production logic. A single content can thus automatically be declined into several thousand versions, all aligned with the initial design and defined marketing pressure rules. The impact is twofold: +30 to +45% click-through rate observed, and a 30 to 60% reduction in production time depending on cases.
By centralizing logic in the template and shifting complexity to a real-time engine, Reelevant enables true scalability: personalization is no longer a human resource constraint, but a structural capacity of emailing
Dartagnan x Reelevant = Less production, more strategy
