SKU Agency Review: A Game-Changer for Email & SMS Marketing?

Picture this: You’ve poured your heart into your DTC brand, but your email campaigns feel like shouting into the void. Open rates are meh, conversions are lackluster, and SMS? You’re not even sure where to start. That was me—until I stumbled upon SKU Agency, a boutique marketing shop promising to turn Klaviyo into a revenue-generating machine. Spoiler: They delivered.

Specializing in email, SMS, and push marketing for direct-to-consumer brands, SKU Agency boasts Certified Klaviyo Master status and a track record of driving 40%+ revenue lifts for clients. But does their service live up to the hype? Here’s my deep dive after partnering with them.

1. Strategy That Actually Moves the Needle

SKU Agency doesn’t just blast generic promotions—they build systems. My onboarding kicked off with a forensic audit of my existing flows (or lack thereof). Their team pinpointed gaps in my welcome series, cart-abandonment triggers, and post-purchase follow-ups, then rebuilt them with hyper-personalized touches.

• Segmentation Sorcery: They sliced my list into laser-targeted groups (new subscribers, repeat buyers, window shoppers) and tailored messaging to each.
• Timing Tweaks: Instead of bombarding customers, they optimized send times based on my audience’s habits—resulting in a 28% spike in open rates within weeks.
• A/B Everything: Subject lines, CTA buttons, even emoji placement got tested relentlessly.

Minor gripe: Their strategy docs were slightly overwhelming at first—think 15-page playbooks—but their team walked me through every detail.

2. Klaviyo Mastery That Feels Like Magic

As Klaviyo nerds (certified ones, no less), SKU’s team maximizes every feature. They transformed my clunky flows into buttery-smooth customer journeys:

• Automation That Converts: Their "Win-Back" flow for lapsed customers generated $12K in recovered revenue in month one.
• SMS Done Right: I’d avoided SMS for fear of annoying customers, but their segmented, value-first approach (think early access vs. discount blasts) made it my top ROI channel.
• Data-Driven Adjustments: Weekly reports highlighted what worked (e.g., "Your ‘Restock Alert’ SMS drove 3x more clicks than email") so we could double down.

Note: If you’re not on Klaviyo yet, they’ll strongly nudge you there—but their expertise justifies it.

3. Results That Speak Louder Than Buzzwords

Within 90 days, my metrics looked like a different business:

• Revenue from email/SMS up 42% (matching their 40% claim).
• CTRs improved by 35% thanks to their obsession with hooks and urgency.
• Fewer unsubscribes, even as send frequency increased—proof their content resonated.

Their "profit-first" mindset also meant scrapping vanity metrics (goodbye, bloated lists) in favor of high-intent buyers.

Pros & Cons at a Glance

✅ Strengths:

• Klaviyo experts who optimize every pixel of your campaigns.
• SMS strategies that feel human, not spammy.
• Transparent reporting—no jargon, just actionable insights.
• Scalable systems for Black Friday/Cyber Monday chaos.

⚠️ Considerations:

• Premium pricing (worth it for growth-stage brands, but startups might need to budget).
• Klaviyo-centric—if you’re married to another platform, they’ll likely push a migration.

Final Verdict: Worth the Investment?

If you’re serious about unlocking email and SMS as profit centers—not just checkboxes—SKU Agency is a powerhouse. Their blend of data rigor and creative flair turned my underperforming lists into reliable revenue streams. While they’re not the cheapest option, their 40%+ average lift isn’t a fluff stat—it’s what happens when masters craft your messaging.

For DTC brands ready to scale, this might be the missing piece. Just don’t be surprised when your inbox starts feeling like a goldmine.
