Klaviyo Flows That Recover Revenue Your Store Is Leaving Behind
Most Shopify stores send a welcome email and a broadcast sale, and leave the rest of their subscriber list idle. Structured Klaviyo flows change that. Every abandoned session, every completed purchase, and every lapsed customer becomes a trigger point for a targeted, automated sequence designed to bring them back.
Build Grow Scale builds flows that work as a system, not a set of disconnected messages. The logic between sequences (timing, suppression, re-entry conditions) is as important as the copy inside them.
Welcome, Abandoned Cart, Post-Purchase, and Win-Back Flows
A complete Klaviyo flow implementation covers four lifecycle moments where automated email consistently outperforms broadcast campaigns. Build Grow Scale designs and deploys each sequence with copy, timing, and conditional logic calibrated to your brand and product category.
- Welcome series: introduces your brand, sets purchase intent, and converts new subscribers before they go cold
- Abandoned cart and browse abandonment: re-engages shoppers who left without buying, with product-specific messaging and structured send timing
- Post-purchase sequence: reinforces the buying decision, drives repeat purchase, and collects reviews at the right moment
- Win-back campaign: targets lapsed customers with a defined re-engagement path before they become permanently inactive
A Klaviyo Agency That Builds for Long-Term Email Performance
Flow implementation is the starting point, not the whole picture. Build Grow Scale approaches Klaviyo as a revenue channel that requires ongoing architecture decisions: which segments receive which flows, how sequences interact, and how the account evolves as your catalogue and customer base grow.
Every engagement delivers more than flows. The systems we configure around those flows determine whether they perform consistently for months, not just weeks after launch.
What a complete Klaviyo engagement covers
- Full core flow suite built from scratch or audited and rebuilt from existing drafts
- Conditional send logic, re-entry rules, and cross-flow suppression to prevent over-sending
- Segment-specific messaging tailored to purchase history, browse behaviour, and customer lifetime value tiers
- Email copy structured for the Klaviyo channel: subject lines, preview text, body hierarchy, and CTA placement
- Mobile-optimised template design consistent with your brand
- Deliverability configuration covering list hygiene, sender reputation, and domain authentication
Klaviyo Email Marketing Built on Clean Lists and Inbox Placement
A well-designed flow that lands in the spam folder generates nothing. Deliverability is a foundational requirement, not a secondary concern. Build Grow Scale configures your Klaviyo account to protect sender reputation from day one, through structured list hygiene, suppression lists, engagement-based send frequency, and authenticated sending domains.
Segmentation determines which subscribers enter which flows and when. We build segments around Shopify purchase data (product category, order frequency, average order value, and recency), so each automated sequence reaches the subscribers most likely to act on it.
Klaviyo Flows Built on Your Shopify Data
Klaviyo's native Shopify integration passes event data (product views, add-to-cart actions, completed orders, and refund events) directly into your flow triggers and segment conditions. Build Grow Scale configures that integration correctly so your flows respond to actual customer behaviour rather than scheduled broadcasts.
This means an abandoned cart flow references the exact products left behind. A post-purchase sequence surfaces relevant complementary products from your catalogue. A win-back campaign uses real purchase history to determine the right re-engagement offer, not a generic discount applied to everyone who has not bought recently.
How Build Grow Scale Implements Your Klaviyo Email Marketing
Every Klaviyo engagement starts with a full account and data audit. We do not build on assumptions about what is already configured or what your list segments look like.
01
Account and Data Audit
We review your existing Klaviyo account, Shopify integration health, list state, and any active flows before scoping what to build or rebuild.
02
Flow Architecture and Segment Design
We map the full flow system (which triggers, which segments, which conditional branches) and define the suppression logic before writing a single email.
03
Copy, Design, and Build
Each flow is written, designed to brand, and built in Klaviyo with full conditional logic, dynamic product blocks, and mobile-optimised layout.
04
QA, Launch, and Deliverability Setup
We QA every flow path, configure sending domains and DKIM authentication, warm up the list if needed, and monitor deliverability and engagement after launch.
