&Menzel

BACKGROUND

Introduce your business and what you do there.

I’m the e-commerce manager of Nivion GmbH, a company that offers solutions and products for better sleep.

OPPORTUNITY / CHALLENGE

What challenge were you trying to address with &Menzel?

We hired &Menzel to scale our D2C sleep brand profitably. Our main goals were to lower our customer acquisition costs on Meta, win significantly more new customers, and build email marketing into a real revenue channel. We wanted one partner who managed Meta ads, creative production, and Klaviyo as one connected system instead of separate channels so that paid acquisition and retention worked together.

SOLUTION

What was the scope of their involvement?

&Menzel handles performance marketing for our Shopify store across three areas. The first is full Meta ads campaign management on Facebook and Instagram, covering campaign structure, targeting, budgeting, and ongoing optimization. The second is continuous production and testing of ad creatives. The third is the setup and optimization of our Klaviyo email flows, including the welcome, abandoned cart, post-purchase, and win-back flows. They run these channels as one system, so acquisition, creative, and retention are aligned and build on each other.

What is the team composition?

We work with 2–5 teammates from &Menzel.

How did you come to work with &Menzel?

We found &Menzel through an online search. We chose them because their pricing fit our budget, they were a great culture fit, and their company values aligned with ours.

What is the status of this engagement?

We worked together in May 2025-April 2026.

RESULTS & FEEDBACK

What evidence can you share that demonstrates the impact of the engagement?

We’ve seen clear, measurable improvements across all channels &Menzel manages. Our cost per order on Meta has dropped significantly, and the number of new customers per month has grown several times over. Monthly revenue has grown substantially as well. Email marketing has gone from a minor channel to a meaningful revenue contributor through the Klaviyo flows. Most importantly, the growth has been profitable, and our contribution margin has improved alongside revenue.

How did &Menzel perform from a project management standpoint?

We communicate with &Menzel through virtual meetings, emails, and messaging apps.

What did you find most impressive about them?

What impresses me most is that &Menzel treats paid acquisition, creative, and retention as one connected system instead of separate channels. Most agencies focus on just one of these areas. &Menzel makes sure Meta ads, creatives, and Klaviyo flows build on each other. Their creative work is strong, and we always work with a senior, hands-on team that understands our business and our numbers rather than handing us off to juniors.

Are there any areas they could improve?

Nothing major comes to mind. The collaboration has been smooth, and the team has consistently delivered what we agreed on.
