iusti ikert product copywriter and brand voice strategist ceo and founder at in between the lines

Hi!

I’m Iusti.

 

I work with purpose-driven, product-led ecommerce brands to bring clarity to their messaging across websites, product pages, campaigns, and everyday content.

My role sits between strategy and execution: helping teams translate what they stand for into language their customers actually understand and trust.

 

As an external copywriter, I collaborate closely with in-house marketing teams and founders across ecommerce and SaaS.
The goal isn’t louder copy but clearer decisions, consistent tone, and messaging that holds up as the brand grows.

Below is a selection of client work where clarity, responsibility, and brand consistency guided every decision.👇🏻

[ PRODUCT-LED SUSTAINABILITY COPY]

💚

Copy for brands where products, proof, and responsibility all have to hold up.

Product-led sustainability copy is where clarity, responsibility, and real-world performance meet.

 

I work with brands whose products do the heavy lifting, where materials, sourcing, formulation, and function matter, and where messaging has to hold up across product pages, campaigns, and paid channels.


My role is to translate that complexity into clear, credible copy that supports trust, decision-making, and long-term growth without dilution, exaggeration, or greenwashing.

 

This copy isn’t written in isolation.

It’s built to work across ecosystems: websites, launches, lifecycle messaging, and paid acquisition, always grounded in what the product can genuinely stand behind.

About
waterdrop

waterdrop® is a product-led hydration brand focused on reducing single-use plastic through design-driven, functional, and sustainable alternatives. Operating across multiple European markets, the brand balances innovation, health-related claims, and sustainability, all within a highly regulated category.

 

Over a multi-year collaboration, I have been supporting waterdrop’s Romanian market as part of cross-functional marketing teams, working across product, lifecycle, and campaign copy.
My focus was ensuring clarity and consistency across touchpoints, from product and collection pages to launches and ongoing communication, while adapting messaging to local language, cultural nuances, and compliance requirements.

 

This long-term partnership reflects the kind of environments I work best in: product-first brands, evolving teams, and messaging systems that need to scale without losing trust.

OUR BRIEF

Their marketing department was looking for copywriting and copyediting support and consultancy for the Romanian market, specifically working on product launches, email campaigns, blogging, social media support and customer-specific support.

In addition to lifecycle, product, and CRM copy, I supported paid acquisition by writing and localising Meta and Google Ads copy for European markets. This included remarketing ads, promotional campaigns, and product launches, written within platform constraints and compliance requirements.

OUR RESULTS

We collaborate on daily social media creation, meta and google ads, email newsletter creation and improvement of the CRM flow. The Romanian market expanded alongside the other European markets and became a growing and powerful market for the sustainable waterdrop products.

CAMPAIGN HIGHLIGHTS

PAID ADS COPY - META & GOOGLE

Alongside brand and product messaging, I’ve spent the last four years writing paid ads copy for Meta and Google as part of in-house and cross-functional marketing teams.

My work focuses on direct-response copy — hooks, primary text, headlines, descriptions, and localisation — written for testing, iteration, and scale within established acquisition strategies.

Media buying, targeting, and performance reporting are handled by the internal teams I collaborate with, allowing me to focus on clarity, compliance, and message performance across markets.

 

What this typically includes:

 

✔️ Meta Ads: hooks, primary text, headlines, remarketing variants

✔️ Google Ads: headline sets, descriptions, intent-based framing

✔️ Localisation for EU markets in regulated categories

✔️ Campaign and launch support aligned with brand voice

 

OUR FEEDBACK

I work with Iustina within the Waterdrop.ro market. Together we prepare copy and marketing texts for the Romanian market […]. I appreciate Iustina’s […] diligence, meeting deadlines, and her ability to adapt to a demanding client like us.

RAGWEAR

The First Vegan Streetwear Brand

sustainability fashion, sustainability copywriting, 100% vegan fashion, began streetware

About
RAGWEAR

Rooted in the vibrant skateboarding scene of the 90s, ragwear has evolved into a sustainable, vegan streetwear brand. Using GOTS-certified organic cotton, bamboo viscose, and recycled materials, it champions eco-friendly fashion. As a “PETA-Approved Vegan” brand, ragwear avoids all animal products, blending ethical values with style to positively impact people and the planet.

 

Today, ragwear balances creative expression with clear values, building collections that feel accessible, expressive, and aligned with a conscious lifestyle.

OUR BRIEF

Ragwear needed ongoing copywriting and copy-editing support across multiple touchpoints and markets.
The focus was on product and collection pages, newsletters, banner ads, and editorial content, supporting both French and English markets while maintaining a consistent brand voice.

The collaboration required clarity at scale: translating design concepts, campaign ideas, and product details into copy that stayed true to the brand’s tone while supporting ecommerce performance.

PAID ADS COPY - META & GOOGLE

Alongside product, collection, and editorial copy, I supported Ragwear’s paid acquisition efforts by writing and adapting copy for Meta and Google Ads.

This included campaign headlines, primary text, and banner messaging aligned with seasonal launches, promotions, and product drops written to reflect Ragwear’s playful tone while staying clear, compliant, and conversion-aware.

Paid media strategy, targeting, and performance optimisation were handled internally by Ragwear’s marketing team. My role focused on crafting product-led, on-brand copy that could be tested, iterated, and scaled across markets.

OUR RESULTS

Over more than two years of collaboration, we worked closely on:

✔️ Product descriptions and collection pages for bi-annual launches

✔️ Ecommerce banners and campaign messaging

✔️ Newsletter content and lifecycle communication

✔️ Blog articles and supporting editorial copy for FR and EN markets

Alongside execution, we refined structure and tone to improve clarity and consistency across channels, helping ragwear maintain a recognisable voice while adapting to different formats, campaigns, and audiences.

The collaboration continues as an ongoing partnership, supporting seasonal launches and day-to-day ecommerce communication.

OUR FEEDBACK

I’ve worked with Iusti for over a year now […] at ragwear, a vegan clothing brand. Our texts often include catchy wordplays and common sayings […] but she always makes them work. She is efficient, time considerate, and always willing to help, even when things change last minute, making sure […] things go out when they should. We’ve collaborated on newsletters, product descriptions, website assets, blog articles, sales collection launches, and promotional content, and she always keeps it on brand while giving it a special voice.
