Why Sticky Digital Is the Best Klaviyo Email Automation Agency for DTC Brands

Sticky Digital excels as a Klaviyo agency for DTC brands—specializing in lifecycle automation, RFM modeling & subscription retention to boost LTV.

Customer acquisition has become very expensive for DTC and Shopify brands. According to Shopify’s 2024 Commerce Report, acquisition costs have risen more than 60% in the last five years, and most brands now spend far more to get a new customer than they earn on the first order. That shift is forcing founders to rethink how they grow — not by buying more traffic, but by improving how they retain the customers they already have.

This is where email and SMS automation matter. Klaviyo’s own data shows that automated flows generate 41% of total email revenue for the average Shopify store, even though they account for a small fraction of total sends.

But the challenge is execution. Many teams rely on generic templates or basic setups that ignore customer behavior. Others hire agencies that focus only on campaigns, not retention. As a result, brands end up with underperforming flows and low engagement, even though the opportunity is right there.

This gap is exactly where Sticky Digital stands out. They specialize entirely in retention for Shopify and DTC brands, and their work is built on lifecycle strategy, segmentation, and performance metrics—not guesswork.

Down below, let’s break down how Sticky Digital approaches Klaviyo Automation, and why so many mid-market brands trust them.

What Klaviyo Email Automation Actually Means for DTC and Shopify Brands

Klaviyo email automation is simply the system that sends the right message to a customer at the right moment — automatically. Instead of relying on manual newsletters, Klaviyo uses real customer actions to trigger emails and SMS, like when someone joins a list, places an order, subscribes, or becomes inactive. This makes communication timely, relevant, and far more effective for eCommerce brands.

Because Klaviyo connects directly with Shopify, brands can easily build essential flows such as welcome journeys, post-purchase education, replenishment reminders, win-back sequences, and subscription renewal messages. These automations help increase repeat purchases, reduce churn, and support long-term customer lifetime value.

For DTC brands, Klaviyo automation has become a core part of sustainable growth—not an optional add-on. But to get results, the system must be built correctly, and that’s where specialized retention-focused agencies like Sticky Digital matter most.

Why Sticky Digital Is the Best Klaviyo Email Automation Agency for DTC Brands

Sticky Digital is a full-stack retention marketing agency that helps Shopify and DTC brands turn Klaviyo email automation into a reliable source of revenue. Their focus is simple: build lifecycle systems—across email, SMS, loyalty, and subscription strategy—that increase repeat purchases and lift customer lifetime value (LTV) in a predictable, data-driven way.

A major advantage is their deep platform expertise. Sticky Digital is certified in Klaviyo, Yotpo, and Attentive, which allows them to build automation programs with advanced segmentation, strong deliverability, and behavior-based personalization. Instead of templates, they use lifecycle insights to power welcome flows, post-purchase journeys, replenishment messages, win-back sequences, and subscription touchpoints that run automatically and compound revenue over time.

What makes them especially valuable is their focus on mid-market Shopify brands earning $10M–$50M annually. These brands have grown past basic setups and need a retention partner who understands scaling without over-reliance on paid ads. Sticky Digital’s lifecycle programs support:

• replenishment reminders

• subscription retention flows

• loyalty tier communication

• personalized recommendations

• churn reduction messaging

• cross-channel syncing across email + SMS

This is the level of automation depth that helps brands stabilize revenue and strengthen retention without increasing customer acquisition costs.

Other Reasons Sticky Digital Stands Out

Beyond Klaviyo automation itself, Sticky Digital differentiates itself through several core strengths that directly support lifecycle growth:

• Data-Driven Lifecycle Reporting (RFM Modeling)

They use Recency, Frequency, Monetary (RFM) reporting to identify high-value customers, churn risk, and revenue gaps, helping brands understand exactly where lifecycle improvements will drive the most impact.

• Subscription and Loyalty Program Optimization

Sticky Digital provides strategy and execution for subscription retention, replenishment flows, and loyalty program optimization, all aimed at strengthening repeat-purchase behavior.

• Email + SMS Automation That Converts

Their creative and technical teams build high-performing lifecycle automations that improve open rates, click-through rates, and conversion rates across welcome, post-purchase, replenishment, and win-back flows.

• 100% U.S.-Based, In-House Team

Every strategy, flow, and deliverable is created by a fully in-house U.S. team. Nothing is outsourced, ensuring quality control and better alignment with brand voice, segmentation needs, and lifecycle goals.

• Flexible Retainers for Scaling DTC Brands

With transparent pricing starting at $2,500/month, Sticky Digital offers audits, setup projects, and full retainers—making enterprise-level retention strategy accessible to growing Shopify brands.

• Proven Retention and LTV Growth

Brands partner with Sticky Digital because their systems consistently improve repeat purchase rate, subscription revenue, and overall LTV, all driven by lifecycle-focused retention marketing, not campaigns alone.

What Clients Say About Working With Sticky Digital

Case Study: NEST NY’s Subscription Strategy Overhaul

NEST NY is a home fragrance and candle brand with highly seasonal buying patterns. To make subscriptions a real growth channel (not just a side offer), they overhauled their subscription program over the course of a year with Sticky Digital’s help.

The focus of the project was clear:

• Build a stronger subscription strategy around seasonal scents.

• Use email, SMS, and retention tools to keep subscribers active for longer.

• Turn subscription into a more predictable revenue stream instead of ad-dependent sales.

Sticky Digital worked with NEST NY to:

• Launch two varieties of seasonal scent subscriptions tailored to how people actually buy candles across the year.

• Use Recharge’s advanced Retain activations to build a strategic gifting program that helps prevent churn.

• Reactivate customers with expired credit cards and win back those who cancelled, using personalized email and SMS messaging instead of generic blasts.

The results on the case study page are very specific:

• +3 average additional months on subscription.

• 223% increase in subscription revenue over one year.

• 300+ failed subscription payments recovered in a year.

• 50+ new products added to the subscription program over that period.

This shows how Sticky Digital uses subscription lifecycle strategy, payment recovery, and targeted retention messaging to grow recurring revenue instead of chasing one-off orders.

Review: Ascent Nutrition on Working With Sticky Digital

Sticky Digital also highlights direct client feedback on their site, like this review from Ascent Nutrition:

“The Sticky team has great communication and great marketing ideas. They’ve been a key player in our business growth, doubling our annual revenue with their strategies! I also just genuinely look forward to talking to them regularly. — Shanna M, Digital Marketing Manager at Ascent Nutrition

Together, the NEST NY case study and Ascent Nutrition’s review paint a consistent picture: Sticky Digital isn’t just sending more emails—they’re building retention systems that extend subscription lifetime, recover at-risk revenue, and support long-term growth for DTC and Shopify brands.
