The Bundesverband Digitale Wirtschaft (BVDW), Germany’s leading digital economy association, released a comprehensive guide to email marketing on March 18, 2026. The 24-page document, crafted by senior practitioners from United Internet Media, Mapp Digital, ELAINE technologies, and AZ Direct GmbH, covers key topics including campaign metrics and the emerging challenge of artificial intelligence (AI) consumer agents filtering emails before they reach human recipients.
As email volumes continue to grow, capturing consumer attention has become increasingly difficult. The Radicati Group projects that over 376 billion emails are sent and received globally each day in 2025, with estimates suggesting this number will exceed 393 billion by 2027. The BVDW guide highlights that attention has evolved into the scarcest resource in modern marketing.
Within the DACH region, email remains a vital communication tool. The ARD/ZDF Medienstudie 2025 indicates that 78 percent of German-speaking residents aged 14 and older engage with email at least once per week. Notably, over 95 percent of Generation Z possess an email address, primarily for online shopping and social media registrations. Research from United Internet Media underscores the commercial impact of email, revealing that 88 percent of Germans find order-related information sent via email important, while 69 percent prefer using email to contact retailers, surpassing both telephone and chat methods. This data reinforces the guide’s assertion that email serves as a strategic impulse driver throughout the customer journey.
Marketers globally are drawing similar conclusions. A survey conducted in December 2025 found that 65 percent of senior business leaders plan to reinvest in email marketing as a dependable owned channel in 2026. Among respondents, 41 percent anticipate significant growth in email and CRM investments, while another 44 percent expect moderate increases.
The BVDW guide categorizes emails into four distinct types: Standalone emails, which are campaign-driven and centered around a single call to action; Newsletters, which blend editorial and promotional content; Transactional emails, which are triggered automatically by user actions; and Trigger and event emails, which rely on personalization. This classification aids marketers in determining the appropriate email type for their communication goals, as the chosen format influences design, legal compliance, automation, and measurement.
A critical feature of the guide is its emphasis on two separate measurement categories: Performance metrics, which monitor campaign behavior in the inbox, and Monetary metrics, which assess budget efficiency. The guide warns that without systematic KPI tracking, email marketing risks becoming a “blind flight.” It advises teams to employ automated dashboards and to benchmark quarterly against industry standards to identify trends proactively.
In addressing marketing automation, the guide clarifies that it should not replace strategy but rather enhance it. Effective automation relies on high-quality contact data and segmentation logic. The guide identifies common pitfalls, such as frequency management, which can overwhelm subscribers. Self-service controls allowing recipients to choose their email frequency are suggested as best practices.
AI’s role in email marketing is twofold: as a tool for production and optimization, and as an inbox gatekeeper. The production aspect includes using AI to analyze consumer behavior and generate personalized content, while the gatekeeping role addresses how AI consumer agents filter incoming emails. This shift necessitates machine-readable content and introduces new metrics, such as the AI Agent Approval Rate and the Meaningful Interaction Rate, requiring marketers to adapt their strategies and monitoring infrastructures.
The guide also explores the growing importance of accessibility in email design, particularly in light of the European Accessibility Act. It emphasizes regulatory compliance and the need for technical requirements that accommodate various disabilities, ensuring emails can be accessed by all users. The guide outlines best practices for accessible design, including high contrast, semantic HTML structure, and mobile compatibility.
Email authentication is presented as a non-negotiable technical foundation for combating phishing and spam. The guide details three key protocols: SPF, DKIM, and DMARC, which collectively enhance the security and legitimacy of email communications. It also advises against generic sender addresses, advocating for personalized sender identities to foster credibility.
Moreover, the guide includes a section on the environmental impact of digital marketing. It challenges the perception that digital communications are inherently eco-friendly, noting that every email consumes energy. The authors advocate for more deliberate communication strategies that prioritize genuine value for recipients, ultimately contributing to a lower digital carbon footprint.
The BVDW guide serves as a vital resource for marketing professionals navigating an increasingly complex landscape. As technology evolves and regulations tighten, the necessity for sophisticated email marketing strategies that prioritize trust, security, and relevance becomes paramount. The guide articulates a vision where email remains a powerful communication channel, provided that marketers adapt to the shifting dynamics of consumer behavior and technological capabilities.
