20 years of email marketing

Millions of customers, the highest standards

Die Schweizerische Post faced a particular challenge: millions of customers across PostFinance, Post and PostAuto expect personalised, relevant and accessible communication. From topic-specific newsletters to highly personalised marketing campaigns – the demands are diverse and the volumes substantial.

Each business unit has its own requirements: PostFinance requires secure, regulation-compliant financial communication. Post communicates products and services for private and business customers. PostAuto provides information on timetables, offers and travel options. All three units share the common goal of reaching customers quickly, relevantly and without barriers.

The central question was: How can a unified email marketing solution be created that covers all business units, guarantees the highest deliverability, and at the same time responds flexibly to individual requirements?

A partnership based on continuity and trust

Since 2004, we have supported Post through this task – over 20 years of continuous collaboration and more than 60 joint projects. This longevity is no coincidence, but the result of a working approach built on mutual understanding, reliability, and shared development.

Our approach was clear from the outset: we do not develop static solutions, but accompany Post through all phases of email marketing. When requirements change, corporate designs evolve, or new legal requirements are introduced, we adapt the solution accordingly. Inxmail Professional has been the ideal foundation throughout – flexible, secure, and scalable.

What sets us apart: we know the systems, processes, and requirements inside and out. Thanks to our long-standing partnership, we can respond quickly, understand interdependencies, and contribute strategically. For larger initiatives, we meet on-site; for ongoing optimisations, we work in an agile manner using Atlassian Confluence, Jira, and Miro Boards. This combination of personal contact and efficient digital processes makes the collaboration particularly valuable.

From the First Templates to the Cloud – A Success Story in Projects

Over 60 joint projects in 20 years – that's more than three projects per year. Behind this figure lies a continuous evolution, during which we have supported Post through every phase of email marketing.

The collaboration began in 2004 with the development of the first email templates. It quickly became clear that Post required a professional solution capable of mapping various corporate divisions. In the early years, individual clients were created for PostFinance, Post and PostAuto. Each division received templates tailored to its respective CI/CD while sharing a common technical foundation. This standardisation made it possible to roll out improvements efficiently across all divisions.

A strategic milestone was the migration to the Inxmail Cloud. Together, we planned and implemented this important step. The result: significantly improved delivery rates, higher performance and new functional capabilities for automated campaigns. The cloud migration laid the groundwork for today's highly automated marketing infrastructure.

For PostFinance, we developed a comprehensive newsletter concept in 2024 that optimises the entire customer journey – from sign-up to unsubscribe. The focus was on optimising the subscription and unsubscription processes with clear user guidance, consolidating profile management across various topic areas, and reviewing existing systems. Particular emphasis was placed on accessibility: all newsletters are designed to be fully accessible to people with visual impairments or blindness.

For Post and PostAuto, we have developed and continuously refined numerous templates over the years. From simple newsletters to complex automated campaigns – the templates now cover virtually every use case. The technological foundation is Inxmail Professional – a proven email marketing platform that combines automation, security and ease of use. Recipient information and content can be seamlessly transferred from third-party systems to Inxmail and redistributed back to surrounding systems.

A solution that grows with the company

The over 20 years of collaboration and more than 60 joint projects demonstrate that the partnership works. It is built on trust, continuity, and mutual understanding – and delivers measurable results for everyone involved.

For Post's customers, the solution means receiving relevant, personalised emails that address their needs. The optimised customer journey at PostFinance ensures that sign-ups and unsubscribes work intuitively. Accessible templates enable all people, regardless of visual impairments, to engage with the content. Post is thus a pioneer in digital inclusion.

For editors at Post, the Inxmail solution has significantly simplified their daily work: they can work independently and efficiently, templates are flexibly customisable, and new campaigns can be implemented quickly. The high degree of automation saves time and reduces manual errors.

For Post as a company, the consolidated platform creates efficiency across all group divisions. Improvements can be developed centrally and rolled out decentrally. The cloud migration has improved delivery rates and opened up new functional possibilities. The solution is scalable and future-proof – ready for new requirements, legal regulations, and technological developments. The collaboration continues to evolve: current topics include, for example, the further personalisation of customer journeys and the use of AI-assisted workflows within the browser-based, intuitive web solution.
