BLOG - Newsletter Advertising in Germany: What the Data Shows
The German newsletter market is no longer an emerging opportunity. Audiences are built, engagement is high, and inventory is available at scale. What has been missing is the data to back the conversation – until now.
Together with morningcrunch, one of Germany’s fastest-growing newsletter publishers, Passendo has compiled the first dedicated research report on newsletter advertising in the German market. What it shows is hard to ignore.
How Does Newsletter Advertising Actually Perform in Germany?
Based on 2025 performance data from inside the German market, newsletter open rates are running at more than double the industry average. Native ad placements are delivering click-through rates several times higher than standard digital formats.
These are not projections. The numbers come from real campaigns, real sends, and a real audience, tracked through Passendo’s ad serving infrastructure and morningcrunch’s publisher data.
The full benchmarks, including deliverability rates and available monthly impressions, are published in the report.
Why the Inbox Works Differently
Newsletter audiences opted in. They chose the publication, opened it on schedule, and read it with intent. That is structurally different from a social feed or a display placement, and the numbers show it.
The report breaks down how newsletter advertising compares to social and display across audience intent, targeting quality, brand safety, and fraud risk. The gap is significant.
What This Means for Publishers and Advertisers in 2026
FAQ
For publishers, the report outlines which monetisation models are working, which inventory is being systematically undervalued, and five practical actions to attract and retain advertiser spend.
For advertisers, it answers a question that comes up in almost every conversation about this channel: why do brands that try newsletter advertising tend to come back?
The answer is in the data.
What open rates can newsletter publishers in Germany expect?
Top-performing German newsletters are achieving open rates well above the industry average of around 21%. The gap between high-quality newsletter publishers and the broader email marketing benchmark is substantial – the full figures are published in The Inbox Opportunity report.
What CPM can publishers charge for newsletter advertising in Germany?
CPMs for newsletter advertising in Germany range from €1 for broad-reach inventory up to €60 for premium, niche publishers with highly engaged audiences. Where a publisher sits in that range depends on audience quality, targeting capability, and ad format. Source: The Inbox Opportunity, Passendo x morningcrunch, 2026.
Is newsletter advertising in Germany growing?
Yes. Subscriber bases at leading German newsletter publishers are growing at roughly 40% annually, based on 2025 data. The report draws a direct parallel to the German podcast advertising market, which grew by over 1,100% between 2015 and 2024, and argues that newsletters are at the same early inflection point now.
