“WhatsApp has become a strong and reliable channel for us. With Zefir, we’re seeing consistent results month after month, especially during collection launches and seasonal campaigns.”

Elyndi partnered with Zefir to transform WhatsApp and SMS into structured retention channels — combining automated flows, behavioral triggers, and targeted promotional campaigns.

Within a short implementation period, Elyndi generated an additional 15% in revenue by activating personalized customer journeys and running highly targeted fashion campaigns.


About the brand


Elyndi is one of Latvia’s leading online apparel and fashion retailers, known for curated collections, seasonal drops, and high repeat purchase rates.

With growing traffic and consistent paid acquisition, the team wanted to:

  • Increase customer lifetime value

  • Recover lost revenue from abandoned sessions

  • Launch collections faster

  • Communicate directly with engaged buyers

  • Build a predictable retention engine


They needed more than occasional SMS blasts.
They needed structured automation at scale.



1. Omnichannel setup: WhatsApp + SMS


Zefir was integrated into Elyndi’s ecommerce system to enable:

  • Real-time behavioral tracking

  • Audience segmentation

  • Automated flow triggering

  • Centralized campaign management


Both WhatsApp and SMS were activated as coordinated channels, allowing:

  • Channel fallback logic

  • Segmented messaging by engagement level

  • Campaign-level revenue tracking

  • Full visibility into incremental revenue contribution


This ensured no revenue opportunity was missed.


2. Automated flows at scale


Elyndi implemented a full suite of personalized automated flows:

  1. Cart abandonment

Triggered when users added items but did not proceed.

  1. Checkout abandonment

Timed reminders optimized for high-intent recovery.

  1. Welcome series

Structured onboarding sequence for new subscribers introducing the brand and best-selling items.

  1. Post-purchase flows

Follow-ups designed to increase repeat purchase rate and strengthen brand loyalty.

  1. Upsell and cross-sell sequences

Personalized product recommendations based on purchase history and browsing behavior.


Each flow was dynamically personalized based on:

  • Product category

  • Cart value

  • Purchase history

  • Customer lifecycle stage


These flows ran continuously in the background, generating incremental revenue without additional ad spend.


3. Targeted campaign strategy


In addition to automation, Elyndi used Zefir for high-impact campaign launches, including:

  • New collection drops

  • Product launches

  • Flash sales

  • Seasonal promotions

  • Bestseller restocks


Campaigns were:

  • Sent to segmented customer groups

  • Optimized for mobile-first engagement

  • Designed with short, conversion-focused messaging

  • Tracked with clear revenue attribution


Below is an example of just one of their seasonal campaigns that generated 11.9K EUR in extra revenue with 20.65X ROI on WhatsApp spend.


Because Elyndi operates in a fast-moving fashion environment, the ability to execute campaigns quickly was critical.

With Zefir, campaigns could be prepared and launched within minutes — not days.


Why Zefir worked for Elyndi


Zefir provided:

  • WhatsApp Business API access

  • SMS campaign infrastructure

  • Automated behavioral flows

  • Audience segmentation

  • Revenue attribution tracking

  • Centralized campaign management


Instead of relying only on paid acquisition and email, Elyndi built a scalable retention system integrated directly into their ecommerce operations.

Conclusion: From Promotional Channel to Predictable Revenue Engine


Elyndi’s results demonstrate that WhatsApp and SMS, when implemented with structured automation and precise segmentation, can become core revenue drivers — not just marketing add-ons.


By combining:

  • Continuous automated recovery flows

  • Personalized post-purchase journeys

  • High-impact seasonal campaigns

  • Real-time audience segmentation

  • Clear revenue attribution


Elyndi transformed messaging into a predictable, measurable retention engine.

The additional 15% revenue uplift was not driven by increasing ad spend — but by activating existing traffic and customer demand more effectively.


Instead of relying solely on email or paid acquisition, Elyndi now operates with:

  • A scalable retention infrastructure

  • Faster campaign execution

  • Higher engagement rates

  • Clear visibility into messaging-driven revenue


For a fast-moving fashion ecommerce brand, this means greater control over launches, stronger repeat purchase behavior, and measurable growth powered by direct customer communication.


With Zefir, WhatsApp and SMS are no longer secondary channels.

They are embedded revenue infrastructure.
