JUNGLÜCK
We want to be different — better. That was the premise behind the cosmetics brand JUNGLÜCK when it launched in 2018. They deliberately set out to change not just the cosmetics market, but also the mindset and behavior around more sustainable beauty.
The brand focuses entirely on sustainable skincare and cuts everything that isn’t needed. Only natural ingredients are used, producing as little waste as possible.
On top of that, production happens exclusively and regionally in Germany. All of this makes JUNGLÜCK a pure, sustainable, and above all natural skincare line that takes honest responsibility for our environment.
JUNGLÜCK Testimonial
“We can warmly recommend working with Mailody. Not just in day-to-day business, but also on big projects like switching to a dedicated IP address, the team — Tizian in particular — has been a huge help. Especially on complex topics around our email marketing tool Klaviyo, having a great partner like Mailody by our side is incredibly valuable. I’m looking forward to the next projects!”
Starting point at JUNGLÜCK
We kicked things off by running a status quo check with the tool 360inbox and realized that some highly relevant email service providers were either marking JUNGLÜCK emails as spam (Gmail) or blocking them completely (T-Online).
The distribution of the database showed that even smaller segments like T-Online & Freenet account for significant revenue overall — especially because email marketing lets us interact with existing customers very cost-efficiently. Unblocking T-Online alone would lead to 6-figure additional annual revenue.
Every step of the technical change was validated via a seedlist test. We sent to a group of different test email addresses to check whether there were spam issues or even full blocks anywhere.

Deliverability setup for JUNGLÜCK
After more than 1.5 years of successful collaboration with JUNGLÜCK, we used a calmer period of the year to dig into deliverability — specifically bouncing of T-Online & Freenet email addresses. (With the standard Klaviyo setup, you usually can’t deliver to T-Online and, in some cases, other inboxes.)
Together, we wanted to bring clarity to deliverability, because most e-commerce companies have blind spots: you send your emails normally without realizing that, with certain email service providers, they land in spam or are blocked entirely.
Below we explain how we reworked the setup so that JUNGLÜCK is now ideally positioned for the advent calendar launch and the upcoming Q4.
Our implementation steps explained
Implementing the Dedicated Sending Domain
Since many parties already send from the root domain, we chose a subdomain setup and added the corresponding DNS records. After that, we ran a multi-week warmup of the email infrastructure. From that point on, domain reputation is no longer built up on Klaviyo / Sendgrid but directly on the JUNGLÜCK domain. It also removes the "sent by Klaviyo" note from emails and prevented messages from being categorized as spam in Gmail. Altogether, this already had a positive impact on deliverability.
Implementing dedicated IP + rDNS + Custom Link Tracking + DMARC
Even if this headline sounds cryptic to non-IT people, every one of these steps matters. We requested most of them directly from Klaviyo and then implemented them in JUNGLÜCK’s backend. That put all the technical prerequisites for an optimal setup in place and also fulfilled the requirement to deliver to T-Online.
Automated Warmup Process
Because Klaviyo is built on Sendgrid, an automated warmup process has to be used. That means when you switch to a dedicated IP, you don’t need to reduce sending volume — you can keep sending as normal. In the background, volume is slowly shifted from the shared IP to the dedicated IP until, after about 30 days, all volume runs on the dedicated IP.
Recovering T-Online addresses
In Klaviyo, addresses that bounce are automatically suppressed and can no longer be contacted. It’s therefore worth recovering T-Online addresses that were suppressed due to bounces and slowly adding them back into the list.
Together, we were able to...
Successfully deliver emails to T-Online, projected to generate 6-figure additional revenue over the next 12 months.
Land emails in the Gmail inbox again instead of spam.
Identify the blind spots and understand exactly which JUNGLÜCK emails arrive and which don’t. That clarity lets us spot issues faster and react directly.
