“Our partnership with Zefir has been a successful step in strengthening our retention strategy. WhatsApp has proven to be a strong and personal channel for staying connected with our customers, while delivering measurable results.”

Aliness.co.uk partnered with Zefir to implement a structured WhatsApp retention system focused on personalized communication, lifecycle automation, and strict policy compliance.

By activating checkout recovery, replenishment flows, and targeted campaigns, Aliness generated an additional 19.64% in revenue — without increasing paid acquisition spend.


About the brand

Aliness.co.uk is a UK-based supplement brand with over 52,000 customers.

The brand serves the broader UK wellness market while maintaining strong connection with the Polish diaspora community across the United Kingdom.


Because supplements are repeat-purchase products, long-term growth depends on:

  • Customer retention

  • Timely replenishment

  • Trust-based communication

  • Educational positioning

  • Policy-compliant messaging


Supplements fall into a sensitive category under WhatsApp commerce and health-related policies. This makes compliance a critical foundation for long-term messaging success.


1. Full compliance setup and policy management


Health and supplement brands face strict guidelines under WhatsApp commerce policies. Non-compliant messaging can result in:

  • Template rejection

  • Messaging restrictions

  • Account warnings

  • Business suspension


As an official Meta Business Partner, Zefir handled:

  • WhatsApp Business API setup

  • Template structuring and approvals

  • Policy-aligned messaging formatting

  • Commerce compliance validation

  • Ongoing campaign review and monitoring


All messaging was structured to comply with health-related communication policies while maintaining strong performance.

As a result, Aliness has been successfully leveraging WhatsApp as a personalized retention channel for over one year — without disruption.

For supplement brands, sustainable compliance is as important as ROI.

2. Personalized WhatsApp retention flows


Zefir implemented a structured lifecycle automation system, including:

  1. Checkout abandonment flow

Automated reminders for customers who initiated checkout but did not complete purchase.

  1. Welcome series

Personalized onboarding sequence introducing the brand, product philosophy, and bestsellers.

  1. Post-purchase flow

Follow-up communication focused on usage guidance, customer support, and cross-sell recommendations.

  1. Replenishment flow

Timed reminders based on estimated supplement consumption cycles.

For supplement brands, replenishment timing directly impacts recurring revenue.

Instead of relying on organic return behavior, Aliness proactively re-engaged customers at the right moment.


3. Community-driven communication strategy


A key part of Aliness’ strategy is serving the Polish diaspora in the UK.


WhatsApp enabled:

  • More personal communication

  • Language-relevant messaging

  • Community-based engagement

  • Higher trust through direct interaction


Rather than sending generic mass campaigns, Aliness structured communication to feel:

  • Direct

  • Personal

  • Culturally aligned

  • Educational


This strengthened loyalty and increased repeat purchase frequency.

4. Targeted WhatsApp campaigns


In addition to automation, Aliness executed structured campaigns including:

  • Bestseller promotions

  • Seasonal supplement bundles

  • Educational product-focused messaging

  • Category-based awareness campaigns


Campaigns were:

  • Sent to segmented customer groups

  • Optimized for engagement

  • Fully tracked with revenue attribution

  • Structured within policy guidelines


WhatsApp consistently delivered higher engagement compared to traditional email marketing.
