Analytics & Testing
Benchmarks are useful context, not targets. Here are current ecommerce email benchmarks and the metrics we would actually use to decide whether a retention program is improving.
Retention Strategy
Customer retention marketing should improve what customers do after acquisition. Here is the system we use to think about first purchase, second purchase, repeat behavior and LTV.
Retention Strategy
Acquisition creates customers. Retention determines how much those customers are worth. Here is how to identify which side of the equation is limiting growth.
Retention Strategy
Subscription customers move through distinct lifecycle stages. Here is what email, SMS and retention strategy should do before the first renewal, after renewal and before churn.
Retention Strategy
Subscription retention starts long before cancellation. Improve product use, first renewals, billing reminders, flexibility and subscriber communication before relying on winback.
Retention Strategy
Email marketing cost is more than your Klaviyo bill. Here is how software, people, campaigns, flows, design and retention management add up for established ecommerce brands.
SMS & WhatsApp
The best SMS messages are short because the idea is clear, not because SMS has to sound robotic. Here are practical ecommerce examples for moments worth interrupting customers for.
Email Campaigns
A better subject line can improve a campaign, but it cannot rescue an audience trained to ignore you. Here is how we think about subject lines inside the wider email system.
Email Automations
Most cart flows jump to a discount too quickly. These abandoned cart examples show how to recover buying intent without teaching every customer to wait for a coupon.
Email Automations
The first 72 hours after signup are some of the highest-intent hours in the customer relationship. These welcome email examples show what to send beyond the discount.
Retention Strategy
Email agency pricing ranges from basic execution to senior retention management. Here's what actually drives the cost and how to tell whether an agency is worth the retainer.
Email Campaigns
Good ecommerce email design is not about making the prettiest email in the inbox. It is about making the message easier to understand and the next action easier to take.
Email Campaigns
Email fatigue is usually not caused by one magic send-frequency number. Repetitive content, weak segmentation and irrelevant promotions are often the bigger problem.
Retention Strategy
Most churn reduction happens before a customer tries to cancel. Fix the offer, first renewals, product usage, billing reminder and flexibility before relying on winback.
Analytics & Testing
Subscription brands need a different scorecard. Starts, cancellations, net growth, churn and cohort retention tell you far more than inflated attributed revenue.
Retention Strategy
For sophisticated ecommerce brands, we would choose Klaviyo. Mailchimp can absolutely run ecommerce email, but Klaviyo gives retention teams a deeper customer-data and lifecycle platform.
Retention Strategy
The best Klaviyo alternative depends on why you want to leave. Omnisend is the closest like-for-like option, but pricing, SMS, send volume and lifecycle complexity can point elsewhere.
Retention Strategy
Klaviyo is still our default platform for sophisticated ecommerce brands. It is powerful, expensive at scale and only worth the premium if your team actually uses the depth.
Retention Strategy
We build and run email and SMS retention programs around repeat purchase rate, reorder timing and customer LTV, not vanity metrics.
