Most e-commerce brands know email matters. It’s a direct line to your customers, free from algorithms and social feeds.
But here’s the reality: very few ecommerce stores consistently generate 20–30% of their revenue through Klaviyo. The average brand is leaving a lot of money on the table.
That’s where an agency-driven approach makes the difference. Instead of “set it and forget it” email marketing, it’s about structured strategy, testing, and optimization that compounds over time. Here’s what we do as a Klaviyo email marketing agency to get our clients into that 20–30% revenue zone.
Step 1: Laying the Foundation
Before diving into flashy campaigns, we start with the basics.
- Klaviyo Account Audit – We analyze flows, campaigns, segments, data syncing, and deliverability. Often, we find major gaps like incomplete integrations or missing flows that cost brands thousands.
- Customer Segmentation – We structure the list around new customers, repeat buyers, VIPs, and lapsed buyers. This ensures every communication is relevant. Sending the same email to everyone is the fastest way to increase unsubscribes and lower conversions.
- Data Hygiene – Without clean data, even the best strategy fails. We clean subscriber lists, remove unengaged profiles, merge duplicates, and validate fields like names, birthdays, and phone numbers. Good data = better personalization and higher deliverability.
This foundation ensures everything we build later has a strong, scalable base.
Step 2: Core Flows (Agency Lens)
Most DIY brands set up basic flows — a welcome series, cart abandonment, and maybe a post-purchase email — and then never touch them again.
That’s a huge mistake.
Flows are where most Klaviyo revenue is generated. But they need ongoing testing and optimization to perform at the highest level.
Here’s how we approach core flows:
- Welcome Flows – Instead of just “sending 3 emails after sign-up,” we test subject lines, content variations, and send timing. For one brand, switching from a discount-led first email to a storytelling-led one boosted conversions by 19%.
- Recovery Flows – Cart, checkout, and browse abandonment flows are goldmines. We experiment with incentive levels, delivery timing (1 hour vs. 4 hours), and even creative formats (plain text vs. design-heavy). The difference can be 10–15% in recovered revenue.
- Retention Flows – Post-purchase journeys drive repeat sales. We optimize cross-sells, upsells, replenishment reminders, and win-back sequences. For high-value buyers, we often introduce loyalty-style messaging to increase customer lifetime value (LTV).
The agency advantage here is simple: we’re constantly testing, adjusting, and refining flows so they don’t go stale.
Step 3: Campaign Strategy
Campaigns are the “pulse” of your email program. They’re what keep customers engaged outside of automations.
We build structured campaign calendars around:
- Seasonal Promos – Think Black Friday, Valentine’s, back-to-school. But we don’t just blast discounts; we build narratives around urgency, exclusivity, and brand voice.
- Product Drops – Coordinated launches with teaser campaigns, early access for VIPs, and follow-ups that highlight scarcity.
- Storytelling Emails – Not every email needs to sell. We send brand stories, founder notes, and customer spotlights that build trust and connection. These non-promotional sends often boost deliverability while deepening loyalty.
This mix prevents list fatigue and ensures every campaign serves a purpose in the bigger growth picture.
Step 4: Ongoing Optimization
The biggest myth in email marketing? That flows and campaigns are “set and forget.”
High-performing Klaviyo accounts evolve constantly. Our agency team provides:
- Copy + Design Updates – Fresh creatives that reflect new offers, trends, and brand voice.
- Deliverability Monitoring – Making sure emails land in the inbox, not spam. A sudden dip in deliverability can cost thousands if unnoticed.
- Reporting & Insights – Beyond open and click rates, we measure revenue per recipient, conversion rates, and customer lifetime value.
- Continuous Testing – From subject lines to send times to CTA placement, small improvements add up to major revenue lifts.
This cycle of optimization keeps accounts sharp, adaptable, and consistently revenue-generating.
Common Mistakes in DIY Accounts
When we audit new accounts, we often see the same mistakes holding brands back:
- Over-reliance on discounts – Training customers to only buy with a code destroys margins and devalues the brand.
- Outdated flows – Welcome and abandonment flows untouched for years, running on autopilot. What worked in 2021 won’t perform the same in 2025.
- No testing or reporting – Without A/B tests and reporting, brands don’t know what’s working, so they keep repeating underperforming strategies.
Fixing these three mistakes alone can unlock huge gains.
