SMS Marketing Service for eCommerce Brands - Retention Side

Why is this
important

Immediate Reach

SMS messages are delivered and read within minutes, making them ideal for time-sensitive communication and urgent actions.

High Intent Engagement

Subscribers who opt into SMS are typically high-intent customers, leading to stronger engagement compared to broader channels.

Funnel Acceleration

SMS helps move customers through the funnel faster, reducing friction between intent and action at key moments.

Strong Email Support

Used correctly, SMS supports and amplifies email campaigns, rather than replacing them, increasing overall retention impact.

Controlled Frequency & Relevance

SMS forces brands to communicate with precision, focusing only on messages that truly matter to the customer.

our Process

Onboarding & Workshops

This phase focuses on understanding how SMS should support your retention strategy without becoming intrusive or overused. We analyze your brand, audience behavior, existing email performance, and customer journey to identify where SMS adds the most value. The goal is to define clear use cases for SMS based on intent, timing, and relevance — not volume.

Activities

Customer Journey Review

Email & SMS Overlap Assessment

Audience Intent Evaluation

Historical Performance Review

Compliance & Consent Check

Clear understanding of when SMS should be used vs. email channels.

Identified moments where SMS can drive faster action and higher intent.

Defined SMS use cases aligned with customer behavior and expectations.

A strategic foundation that prevents overuse and message saturation.

Creation & Implementation

In this phase, we design SMS as a high-impact, low-volume channel. We create intent-driven messages triggered by specific behaviors, define strict rules around timing and frequency, and align each message with a clear purpose. The focus is on delivering the right message at the exact moment it matters — driving action while preserving trust and long-term engagement.

As the system matures, SMS is carefully integrated with other retention channels to ensure communication stays relevant, coordinated, and effective, without increasing message frequency.

Frequently Asked Questions

How often should SMS communication be used?

SMS should be used selectively, not frequently. Within automations, SMS works best at critical touchpoints where speed and immediacy matter. For campaigns, it should be reserved for important announcements only. Because SMS is a highly personal channel, the goal is to drive action without overwhelming subscribers.

There is no single best platform for every brand.

 

While Klaviyo is our primary tool and allows us to keep data under one roof, SMS pricing can vary significantly by country.

 

When cost becomes a factor, our team evaluates alternative platforms based on pricing and ecosystem integrations, ensuring they can be paired effectively with existing tools for maximum impact.

This comes down to simple unit economics. Each platform has clear pricing for SMS and MMS. Through controlled A/B testing, we evaluate whether MMS generates enough incremental conversions to justify the higher cost and what that means for the brand’s profit margins.

SMS is most effective at moments where timing directly impacts conversion, such as order updates, abandoned checkout reminders, back-in-stock alerts, or limited-time offers. These are situations where speed and visibility matter more than long-form explanation, making SMS the most efficient touchpoint.

SMS is not a standalone channel. It works best when integrated with email and other retention touchpoints, supporting specific moments in the customer journey. Used this way, SMS accelerates action without replacing long-form communication or increasing overall message volume.
