Every retention channel
one strategy

Retention is not built through a single channel. We combine ten marketing channels into one connected system designed to increase repeat purchases and customer lifetime value.

Email Marketing service for eCommerce brands from Retention Side agency

Email Marketing

Email marketing helps eCommerce brands turn one-time buyers into repeat customers through structured flows, strategic campaigns, segmentation, and education.

 

It gives you a channel you own, allowing you to communicate consistently, build trust after the first purchase, and increase customer lifetime value without relying only on paid acquisition.

SMS Marketing

SMS marketing provides direct access to your customers through a channel with exceptionally high visibility.

 

Used strategically, it supports critical moments in the customer journey, drives immediate action, strengthens retention efforts, and complements Email marketing without overwhelming subscribers with unnecessary communication.

Push Notification service for eCommerce brands from Retention Side agency

Push Notifications

Push notifications give eCommerce brands a low-friction way to reconnect with visitors and customers without asking for email or phone access.

 

Used strategically, they support reminders, restocks, abandoned sessions, and return visits while keeping Email and SMS reserved for higher-value communication across the customer journey.

Direct Mail service for eCommerce brands from Retention Side agency

Direct Mail

Direct Mail creates a physical brand experience in a world dominated by digital communication.

 

While more expensive than other retention channels, it delivers unmatched memorability, helps re-engage high-value customers, generates word-of-mouth, and creates moments that customers are far more likely to remember and talk about.

Loyalty Program service for eCommerce brands from Retention Side agency

Loyalty Programs

Loyalty programs help transform repeat customers into long-term brand advocates through a structured system of rewards, benefits, and recognition.

 

When designed correctly, they increase purchase frequency, strengthen customer relationships, encourage engagement beyond transactions, and create a retention layer that compounds value over time.

Subscription Program service for eCommerce brands from Retention Side agency

Subscription Programs

Subscription programs create predictable revenue by turning one-time purchases into recurring customer relationships.

 

They improve retention, simplify replenishment, increase customer lifetime value, and provide customers with a convenient way to receive products they already use on a regular basis.

Email Deliverability service for eCommerce brands from Retention Side agency

Email Deliverability

Email deliverability ensures your messages reach the inbox instead of spam or promotions folders.

 

Through proper domain configuration, sender reputation management, list hygiene, and ongoing monitoring, we help maximize inbox placement rates so every campaign, flow, and retention effort has the opportunity to generate results.

ESP Migration service for eCommerce brands from Retention Side agency

ESP Migration

ESP migration allows brands to move from one platform to another without losing customer data, automations, segmentation, or reporting accuracy.

 

We handle the entire transition process, including data mapping, flow recreation, domain configuration, and quality assurance, ensuring a smooth migration with minimal disruption to ongoing retention activities.

Whatsapp Viber marketing service for eCommerce brands from Retention Side agency

Whatsapp/Viber

WhatsApp and Viber provide conversational communication channels that feel more personal than traditional marketing messages.

 

Used strategically, they help deliver timely updates, support customer relationships, and create direct interactions that complement Email, SMS, and other retention channels without adding unnecessary complexity.

Referral programs service for eCommerce brands from Retention Side agency

Referral Programs

Referral programs turn satisfied customers into an acquisition channel by rewarding them for introducing new buyers to your brand.

 

When structured correctly, they create a predictable flow of high-quality customers, reduce dependency on paid advertising, and strengthen loyalty by encouraging customers to actively promote the products they already enjoy.
