How Badsender is building a responsible digital trajectory with Clever Cloud

At Badsender technical choices are never considered neutral. Specialised in email marketing, deliverability and CRM, the agency has progressively evolved its practices to align its digital tools with its commitments to environmental responsibility, ethics and digital sovereignty.

Building digital sovereignty as a trajectory, not a posture

Rather than claiming an ideal stance or a “100% sovereign” label, Badsender chose a different path: transparency. The agency publicly documents its IT stack, openly acknowledging inconsistencies and dependencies, and explaining the trade-offs behind each decision. This approach is not about claiming perfection, but about creating a compass to guide future technical choices.

Open source as the foundation of sovereignty

For Badsender, the reflection quickly went beyond the simple question of hosting providers.

We have always wanted to give back to the community that has given us so much. Publishing LePatron as open source was an obvious choice. The logical next step was to ensure the same consistency on the infrastructure side, maintaining control over hosting, complying with regulatory requirements (GDPR) and remaining mindful of our environmental impact. All while avoiding dependence on proprietary services, particularly those of GAFAM.

This reasoning is fully aligned with Badsender’s DNA: sharing knowledge, documenting practices, and building tools that can be reused by others. It is within this mindset that LePatron was created—an open-source email builder designed to simplify the creation of responsive emails that comply with industry best practices. One key question then remained: where should this web application be hosted in a way that is consistent with these principles?

Why Clever Cloud to host LePatron

From a technical standpoint, LePatron relies on a well-controlled architecture: a Node.js web application, a MongoDB database delivered as DBaaS, and asset hosting. Users are mainly located in Europe, but also in the United States and the Asia-Pacific region, which requires continuous service availability.

Choosing Clever Cloud was not driven by the pursuit of extreme performance, but by a precise balance:

For Badsender, Clever Cloud was selected not to “do more”, but to do things right, in line with both its values and operational constraints.

A pragmatic, prepared and well-supported PaaS migration

The migration to Clever Cloud was anticipated and prepared in advance. The main adjustments involved resource sizing and optimising performance for the specific needs of the application.

Despite the uncertainties inherent in any production deployment—particularly around real-world load—the support provided by the Clever Cloud team helped secure the transition.

The biggest unknown was sizing. Clever Cloud’s support helped us adjust quickly, without any service disruption.

The migration was completely transparent for LePatron users.

Centralisation, clarity and operational peace of mind

After several months in production, the benefits observed are primarily structural. Centralising the application, database and assets with a single provider has significantly simplified the team’s day-to-day operations. Logging and monitoring tools, available from the outset, proved more effective than previously used solutions.

Beyond the technical aspects, the human relationship also played a key role. Having direct access to identified contacts who understand the context of a small European organisation makes a tangible difference compared to large hyperscalers.

A technical choice that became a strong signal for the ecosystem

While end users did not experience any functional change, Badsender deliberately chose to communicate openly about the reasons behind this move: data sovereignty, environmental coherence, and alignment with an open-source vision of digital infrastructure.

This communication generated many positive responses from technical peers, partners and stakeholders within the email and responsible digital ecosystems. Choosing a sovereign cloud for web applications thus became a credibility signal, reinforcing the consistency between Badsender’s discourse and its actual practices.

Clever Cloud as an operational building block for sovereignty

For Badsender, Clever Cloud is neither a symbol nor an abstract promise. It is a concrete and coherent building block that makes it possible to apply principles often discussed only in theory: taking control of data hosting, remaining within a European legal framework, and focusing on what truly matters—the product and its use cases.

A pragmatic choice that allows the agency to keep moving forward: improving its products, supporting its clients, and continuing to challenge the practices of its industry.

Kubernetes vs Docker : Differences and When to Use Them

When people start exploring cloud-native technologies, one confusion comes up almost every time: are Docker and Kubernetes competitors? Do you have to choose between them? And why do people so often talk about Docker “with” Kubernetes?

K8S: What Is Kubernetes, How It Works, and Why It Became the Standard

K8S, short for Kubernetes, is an open source container orchestration system originally developed by Google and donated to the Cloud Native Computing Foundation (CNCF) in 2015. It automates the deployment, scaling, resilience, and networking of containerized applications across clusters of servers. In just over a decade, K8S has become the technical foundation on which a majority of modern cloud applications run.
