#1 konversionsKRAFT

CRO

Bad Homburg, DE · CRO / experimentation + behavioral science · konversionskraft.de · Founded 1996

67/100
Rank #1 of 20 in DACH

konversionsKRAFT: Bad Homburg consultancy founded 1996 by Andre Morys - Germany's largest CRO firm, combining experimentation with behavioural science; runs the growth minded SUPERHEROES conference.

Why konversionsKRAFT ranks #1 in DACH: Three decades of track record and enterprise-grade quantified cases (Haufe +EUR 5.2M growth). It is a CRO consultancy rather than a retention shop, so it scores nothing on Klaviyo-side specialization - and still ranks first.

#2 MAILODY

66/100
Rank #2 of 20 in DACH

MAILODY: Linz-based, Klaviyo-only lifecycle agency - the first Klaviyo Elite partner in DACH and Klaviyo's EMEA Partner of the Year 2026. MAILODY built its own RFM and inbox-testing tools and works with 100+ brands.

Why MAILODY ranks #2 in DACH: The region's specialization leader and Klaviyo's EMEA Partner of the Year 2026: top Klaviyo tier, proprietary data tooling including RFM, and quantified cases (Paul Hewitt email revenue doubled). A thin third-party review base is all that separates it from the UK/US leaders.

RELAIN: Munich founder-led retention boutique (formerly minth) covering email, SMS, WhatsApp, direct mail, loyalty and subscriptions, deliberately capped at 10 brands at a time, now with a second base in Austin, TX.

Why RELAIN ranks #3 in DACH: Strong documented outcomes (SUSHI BIKES +221% email revenue; femtis +197% returning customers) and a weekly retention newsletter. Boutique scale and a plain partner tier limit the ceiling.

#4 Tante-E

CRO

Cologne, DE · Shopify Plus builds + A/B testing and Klaviyo retention practice · tante-e.com · Founded 2018

57/100
Rank #4 of 20 in DACH

Tante-E: Cologne Shopify and Shopify Plus agency of 28 people that pairs store builds and migrations with an ongoing optimization practice: A/B testing, data analysis and Klaviyo retention marketing. Clients include Reisenthel, fritz-kola, LFDY, OACE and 1. FC Union Berlin, with 400+ projects delivered since 2018.

Why Tante-E ranks #4 in DACH: The retention practice hides behind build metrics: its one public Klaviyo case study (Ryzon, six-figure email revenue) currently redirects to the references page, and there is no Klaviyo partner directory profile to anchor the tier. Republishing quantified email numbers would move it up a band.

Why growganic ranks #5 in DACH: The Ankerkraut case (+EUR 234,445/month from 28 winning tests) is one of DACH's best-documented CRO results, and 44 ProvenExpert reviews add credibility. Small team and no premium certifications cap it.

ABxpert: Steinhagen agency doing A/B testing exclusively for Shopify Plus shops, with in-house data, design and dev teams; references include Tom Tailor and LFDY.

Why ABxpert ranks #6 in DACH: Huge claimed aggregates (2,500+ tests, EUR 110M+ verified additional revenue, 250+ shops) drive volume scores, but the claims are self-reported with no reviews or named-case numbers behind them.

retenya: Munich retention brand of ondevi GmbH (~15 German-speaking specialists) running Klaviyo plus WhatsApp, push, loyalty and referral; claims ~EUR 100M/yr client revenue via Klaviyo.

Why retenya ranks #7 in DACH: Marquee client results (AG1 +460% email recipients; TEVEO +81% YoY Klaviyo revenue), but a plain partner tier and no review footprint yet.

#8 sjmedia

Email / SMS

Kuppenheim, DE · Klaviyo email automation for PrestaShop / Shopify / Shopware shops · sjmedia-consulting.de

45/100
Rank #8 of 20 in DACH

sjmedia: Owner-led e-commerce agency from Kuppenheim that builds and maintains PrestaShop, Shopify and Shopware stores and runs a standing Klaviyo practice on top: flow setup, segmentation, sunset logic and monthly optimization retainers. The practice claims 16+ years of e-commerce work and 200+ retailers served.

Why sjmedia ranks #8 in DACH: One quantified case carries the whole results pillar, and the site's 100+ five-star reviews claim has no fetchable profile behind it: the ProvenExpert page sits at zero. A second named Klaviyo case and a live review profile would lift two pillars at once.

amail agency: Klaviyo-only retention agency (amail GmbH) serving 7 to 8 figure DTC brands such as Sheko, Rosental Organics and Overshield, known for pairing Klaviyo with Chatarmin for WhatsApp lifecycle work.

Why amail agency ranks #9 in DACH: The strongest verified specialization in this tier, a Klaviyo Gold Master tier confirmed in Klaviyo's own directory alongside a clean ProvenExpert profile. What is missing is client evidence: the numbers on site are industry benchmarks rather than per-client results, and there are no case study pages.

42/100
Rank #12 of 20 in DACH

Boost it: Berlin growth agency whose retention line covers email, SMS and WhatsApp with RFM segmentation practice, alongside paid and tracking services.

Why Boost it ranks #12 in DACH: Evidences RFM and testing capability, but the agency itself has moved on: the site now leads with AI search and SEO, and retention sits fourth of five service lines. Without a re-centered retention practice and a public Klaviyo credential, this listing is at risk of dropping off.

#13 retention.de

Retention

Walluf, DE · Klaviyo + WhatsApp + print retention system built on repurchase-interval data · retention.de

40/100
Rank #13 of 20 in DACH

retention.de: Two-person retention consultancy from Walluf that wires email, WhatsApp, print mail and customer service into one system steered by data most agencies ignore: per-customer repurchase intervals, real product pairings for cross-sell flows, and churn signals among loyal buyers. Clients named as references include LOCKCARD, Aurum Brothers and Black Label Coffee.

Why retention.de ranks #13 in DACH: The most data-literate retention methodology publicly described in DACH, undercut by anonymous case studies: the strongest numbers (repeat rate 11% to 37%, EUR 230k added) belong to unnamed brands. Naming one case and opening a review profile would move it several places.

Convertlab: Bavarian CRO agency (Convertlab GmbH, incorporated January 2024, Shopify Partner since February 2023) running Bayesian A-B testing for Shopify brands under a five times ROI guarantee, with a CROcast podcast as its content channel.

Why Convertlab ranks #14 in DACH: Volume claims are unusually specific for this tier, 800 plus tests across 70 plus shops, and the Shopify Partner listing is verified. The blocker is its own site: the pages render only in the browser, so no case study, client result or data-practice claim on convertlab.net could be verified by fetch.

Why SiegerKonzept ranks #15 in DACH: Aggressive documented growth cases (EUR 2K to 89K+/month email revenue), but the Klaviyo Master Gold credential vanished with the retention7 rebrand: the directory entry is gone and the site no longer claims a tier.

03 · Methodology

How agencies are scored

Every agency is scored 0-100 across five pillars from publicly verifiable evidence collected in October 2026. Evidence is weighted by tier: independently verified beats self-published, self-published beats claimed. The weighting is ours and deliberately favors data-driven operators; we publish the full rubric so you can disagree with it.

The Data Sophistication pillar is scored from public claims until verified. Earning the ✓ Verified Data-Driven badge means showing the data work behind the listing: a case study or work example we validate by hand, or one free Affinsy analysis on a client store.

Spotted something factually wrong on a listing? Any agency can ask for a correction: corrections ship with the next edition, they are free, and they change nothing about the score.

Questions about this ranking

Which is the best retention and CRO agency in DACH in 2026?
konversionsKRAFT ranks #1 in Affinsy's October 2026 ranking of retention and CRO agencies in DACH, scoring 67 of 100, ahead of MAILODY (#2, 66/100) and RELAIN (#3, 58/100). All 20 agencies in DACH are scored on the same five pillars: proven results, specialization, data sophistication, reputation and track record.
How does Affinsy score retention and CRO agencies?
Each agency is scored 0-100 across five pillars: proven results (30 points), specialization (20), data sophistication (20), reputation (15) and track record (15). Scoring uses publicly verifiable evidence collected in October 2026, weighted by tier: independently verified evidence beats self-published, and self-published beats claimed. konversionsKRAFT scored 67, MAILODY scored 66 and RELAIN scored 58 in DACH.
Can an agency pay to be listed or to rank higher?
No. Rank position is never purchasable and no agency pays to appear in the ranking. Verification is free, and factual corrections to a listing never change the score.
What does the Verified Data-Driven badge mean?
It means the agency stood behind its listing with Affinsy directly and its data-capability claims held up to a hands-on review: a case study or work example, or one Affinsy analysis run on a client store. No agency in DACH carries the badge in the October 2026 edition.
How often is the ranking updated?
Monthly. The current edition is October 2026, last updated October 6, 2026, and the next edition publishes November 4, 2026. Rankings are recomputed from evidence each edition, so positions move between editions.
How is this different from Clutch, G2 or other agency directories?
Review directories order agencies by the volume and rating of client reviews they collect. This ranking scores what an agency has publicly demonstrated: published results, specialization, data capability (segmentation, LTV modelling, basket analysis, structured testing), reputation and track record, each weighted by how independently the evidence can be verified. Review counts feed only the reputation pillar (15 of 100 points), so an agency cannot climb this list on reviews alone.
Which of these agencies specialize in Shopify stores?
RELAIN (#3), Tante-E (#4), ABxpert (#6), sjmedia (#8), Onlineshop Performance (#10) and Convertlab (#14) name Shopify or Shopify Plus in their published focus or case studies in DACH. Most agencies in the list work across Shopify, WooCommerce and Magento; this answer lists only the ones whose public material calls out Shopify specifically.
Which are the best Klaviyo agencies in DACH?
16 of the 20 agencies in DACH reference Klaviyo in their published focus, partner status or case studies: konversionsKRAFT (#1), MAILODY (#2), RELAIN (#3), Tante-E (#4), retenya (#7), sjmedia (#8), amail agency (#9), Onlineshop Performance (#10), Advereo (#11), Boost it (#12), retention.de (#13), SiegerKonzept (#15), Szczerba Solutions (#16), saltylemon (#18), retentionclub (#19) and RECI IT Solutions (#20). The highest-scoring of them is konversionsKRAFT at 67/100.
Which cities are these agencies based in, and do they work with brands elsewhere in DACH?
Headquarters represented in the October 2026 edition: Bad Homburg; Linz; Munich; Cologne; Remscheid; Steinhagen; Kuppenheim; Greven; Rain (LU); Berlin; Walluf; Heilsbronn; Ratingen; Zurich area; Ludwigshafen; Norderstedt; Geisa; Zug. Every agency in the list works remotely with e-commerce brands across Germany, Austria and Switzerland, so a brand in a city not listed here is not limited to local firms.
