About us

Yulie is a Japan-based CRM agency specializing in Shopify × Klaviyo retention marketing. We design, write, and build email and LINE programs that Japanese customers actually respond to — from strategy through hands-on implementation.

Translation Isn’t Localization

Japan’s e-commerce email culture is fundamentally different: image-rich mobile-first design, LINE as a primary channel, unique gifting seasons, and a level of politeness that machine translation gets wrong. Flows copied straight from the US underperform here.

Official Klaviyo Partner

Yulie is a certified Klaviyo partner based in Japan. We build revenue-focused implementations on top of Shopify’s data structure — for Japanese brands, and for global brands entering Japan.

Why work with Yulie

Japan Expertise, Built Into Your Klaviyo

  • 01｜Native Copy & Design

    Keigo-correct Japanese copywriting and mobile-first, image-rich email design that matches what Japanese consumers expect from a trusted brand.

  • 02｜Japan’s Retail Calendar

    New Year sales, Ochugen and Oseibo gifting, Golden Week, White Day — we plan campaigns around the seasons that actually drive Japanese purchase behavior.

  • 03｜Email × LINE Orchestration

    LINE is Japan’s dominant messaging app. We design programs where email and LINE work together as one customer journey instead of competing.

  • 04｜White-Label for Agencies

    Already running Klaviyo for your clients? We slot in as your Japan localization team — under your brand, with all reporting in English.

How it works

Our Process

  • 1｜Japan-Readiness Audit

    We review your current Klaviyo flows, segments, and templates, and map exactly what needs to change for Japan — deliverability, content, timing, and channels.

  • 2｜Localization & Build

    We rewrite, redesign, and rebuild your core flows for the Japanese market — welcome, abandoned cart, post-purchase — plus Japan-specific seasonal campaigns.

  • 3｜Launch & Optimization

    JST-optimized send times, ongoing A/B testing, and monthly reporting in English. Your Japan program becomes a compounding revenue asset.

Flow Examples

How your core flows change when they’re built for Japan.

WELCOME

Welcome Series

First impressions carry extra weight in Japan. We introduce your brand story with the polite, trust-building tone Japanese first-time subscribers expect — and drive the first purchase.

ABANDONED CART

Abandoned Cart Reminder

Recover carts with reminders tuned to Japanese payment habits — including konbini payment and cash-on-delivery users — sent at times that fit Japanese daily rhythms.

POST-PURCHASE

Post-Purchase Follow-up

Turn first-time buyers into repeat customers with review requests, cross-sells, and gifting prompts built around Japanese repurchase behavior.

Beyond CRM

Store Builds & Paid Ads, Covered Too

CRM works best when the store and the traffic are right. We handle both ends in Japan.

  • Shopify logo

    Shopify Development

    Store builds, theme customization, and Japan-readiness for your existing store — Japanese localization, local payment methods, shipping setup, and the legal pages Japan requires.

  • Meta logo

    Meta Ads for Japan

    Paid acquisition that feeds your CRM. We plan, localize, and manage Meta ad campaigns for Japanese audiences — creative, copy, and targeting included.

Why Klaviyo × Shopify

Your Shopify customer data — who bought what, and when — flows into Klaviyo in real time. That stack doesn’t change when you enter Japan. What changes is everything on top of it: language, design, timing, and channels. That’s where we come in.

FAQ

Do we need to switch tools or re-platform?

No. We work inside your existing Shopify and Klaviyo accounts. Japanese-market flows and campaigns are added alongside what you already run.

Do you work with agencies?

Yes — white-label. We act as the Japan arm of your team, under your brand, with all reporting and communication in English.

What about LINE?

We design and implement LINE alongside email — including Klaviyo integrations — so both channels work as one program.

How do we communicate?

Async-first, all in English — email or Slack, with replies within one business day (JST). Everything runs smoothly without meetings.

How do you charge?

Project-based pricing for the initial localization, and monthly retainers for ongoing campaigns and optimization. USD invoicing available.

Can we start with just an audit?

Yes. The Japan-readiness audit is free and comes with a concrete, prioritized list of what we’d change.
