Stellenbeschreibung

About this job

We are looking for you as an E-Mail Marketing Manager (Segmentation) at Mammutmarsch!

At Mammutmarsch, we are more than the pioneers of extreme hiking in Germany. We are a movement. People train for months for our events, cover 30 or 50 kilometers non-stop -- and push their limits.

And that's exactly how we think about marketing.

E-mail is not a newsletter channel for us.

E-mail is a revenue machine.

We are looking for someone who can systematically master Klaviyo.

Someone who understands which message which segment needs to receive when -- and how often -- to measurably increase revenue per user and total revenue.

Do you love testing?

Do you think in hypotheses instead of gut feelings?

Do you want to not just manage a channel, but dominate it?

Then we should talk.

Responsibilities

Strategy & Segmentation

  • Build and prioritize clear segments (purchase behavior, lifecycle, engagement, interests, demographics)
  • Develop a structured targeting blueprint
  • Define sequencing, exclusions, and frequency caps

Experimentation & Testing

  • Develop hypotheses → build variants → test → evaluate → iterate
  • Systematic test process across segments, content, frequency & offers
  • Clean documentation & decision logic

Campaign Planning

  • Weekly and monthly planning of all campaigns & tests
  • Control of conflict rules & sending logic
  • Strategic timing aligned with events, drops, and campaigns

Production & Setup

  • Briefing of copy & design
  • Build testable variants
  • Clean setup in Klaviyo (tracking, UTMs, QA, audience logic)

Analysis & Scaling

  • Interpretation of results (RPR, RPU, CVR, AOV, Guardrails)
  • Derivation of concrete follow-up tests
  • Rollout of successful strategies to larger segments
  • Build a structured content & idea database

Qualifications

  • Proven track record in e-mail/CRM marketing with revenue responsibility
  • Strong experimentation & analytics mindset (you think in hypotheses, variants, signals, decisions)
  • Very good understanding of segmentation, lifecycle logic & targeting
  • Proficiency in Klaviyo (segments, campaigns, A/B tests, QA, deliverability)
  • Ability to correctly interpret metrics such as RPR, RPU, CVR, AOV, Incrementality, Unsub-Rates
  • Intuition for content: You recognize which message fits which segment
  • Structure & systems thinking -- you build processes that work scalably
  • Clarity in briefing copy & design

You don't just want to send campaigns.

You want to build systems.

Benefits

  • A brand with a real community, real emotions, and clear positioning
  • Full ownership of one of the most important revenue channels
  • A team that takes performance seriously
  • Remote work (Germany preferred)
  • 30--40 hours per week
  • Significant creative freedom and real strategic responsibility

We are not about employment here.

It's about impact.

Does this sound like your playing field? Then send us your application by April 15, 2026 at the latest.

We look forward to hearing from you.

Let's turn Klaviyo into a revenue machine together!
