We are pleased to announce that PostPal is now available as the first direct-mail app in the Klaviyo Marketplace for the German market.
From private integration to official app
For more than a year, our customers already had access to a private Klaviyo integration. That solution worked, but one thing was clear to us: when customer data is involved, “it works” is not enough.
With the official app integration, we create transparency, trust and stability. In e-commerce, address and customer data are among the most sensitive information of all.
Webhook-based solutions can be technically secure, but for many companies they feel more like a workaround: data is sent to external servers, monitoring and error handling are complex, and data flows often remain opaque. With the native app in the Klaviyo Marketplace, we now offer a reviewed, robust and bidirectional solution that is clearer and more trustworthy for our customers.
The advantages of the native app integration
Our Marketplace app goes far beyond the standard of a webhook solution:
-
Bidirectional communication: we push events back to your profiles → better segments, enriched data and more possibilities for complex flows.
-
Seamless in Flow Builder: direct-mail campaigns can be added to existing email flows as easily as SMS or email.
-
Detailed reporting: analyze how different customer groups, for example one-time buyers vs. repeat buyers or email openers vs. non-openers, respond to your print campaigns.
-
Data protection and opt-outs: advertising opt-outs can be excluded directly in Klaviyo, with no cumbersome handling across different tools.
Typical use cases
With the integration, direct mail becomes a fixed part of your Klaviyo strategy. Automated campaigns are especially effective, including:
-
Winback and post-purchase flows
-
Browse abandonment
-
Cart abandonment
-
VIP campaigns
Especially with Q4, Black Friday/Cyber Monday and Christmas in mind, our app is the easiest and fastest way to start with direct mail: automated, measurable and high-performing.
Conclusion
With PostPal, direct mail finally becomes as easy to use as email. And with the official Klaviyo Marketplace app, we are setting a new standard: more trust, more data intelligence and more impact for your retention strategy.
