Your Reviews Are the Secret Weapon
We turn real customer feedback into emails that convert traffic into profit, fully done-for-you.
Most brands are sitting on a goldmine of persuasive reviews and don’t even realize it.
The hesitations. The surprise benefits. The emotional triggers.
It’s all there, straight from the people who already bought and loved your product.
We build high-converting emails fueled by your customers’ words, questions, and raw feedback.
No generic templates. No guesswork. Just strategic messaging that speaks directly to where your customer is in the buying journey.
That’s how our clients are pulling 30-50% of their revenue from email alone.
While others spray and pray, we write like your happiest customers are talking to your next ones.

What Our Clients Say
Increasing Email Revenue By 560%
Silva
Manager, Pellequr Spa
Our email marketing has grown tremendously since working with Joshua. Having someone who understands trends, algorithms, and how to match our brand’s voice and design has taken a huge load off our plate. He’s prompt, strategic, and most importantly, he’s driving real revenue. You’ll see subscriber growth and financial results as early as the first month.
Jordan T.
Founder, Cyclone Filter Cleaner
Since bringing Josh on to manage email for Cyclone Filter Cleaner, we’ve seen a 563% increase in reach through email alone. Our list has grown, deliverability has improved, and our presence in the inbox now feels elevated and professional. His reliability is unmatched, and he delivers exactly when he says he will. That consistency has become a quiet but powerful force behind our momentum.
Thomas R.
Co-Founder, Daily Belts
Before working with Joshua, we didn’t have much of an email strategy, just a couple of default flows. He came in and built out 10 custom flows with on-brand design that made our emails feel like a natural extension of our website. We quickly saw improvements in traffic, conversions, and email-driven revenue. The whole process was smooth, fast, and genuinely collaborative.
Why Work With Us?
Joshua Rathbun
Founder, Copyrath
Hey, I’m Joshua, Founder of Copyrath. I built this agency after selling my own DTC brand and realizing how broken most email marketing systems really are.
Most agencies treat your brand like a template. They plug you into the same tired automations, write generic copy, and call it strategy.
We do things differently.
We’re a small, focused team that builds your flows and campaigns around what your real customers are saying. Their words, their objections, their unexpected wins.
That means no fluff, no filler. Just strategic, review-driven emails and SMS that turn casual interest into serious revenue.
If you’re looking for a partner who cares about performance as much as you do and actually builds a system you can rely on, we should talk.
Our founder, Joshua Rathbun, will personally audit your email marketing strategy and send you a free, on-brand email design tailored to your store.

Actionable recommendations to grow your revenue
Why is email marketing important for my brand?
Imagine this. You spend all this time and money getting someone to your site. They buy once, maybe even love the product, and then never hear from you again. That’s where email comes in. It’s your chance to stay in touch, bring them back, and turn a one time buyer into a loyal customer. It’s personal, direct, and it works. Our clients see 30 to 50 percent of their revenue come from email alone. So instead of constantly chasing new customers, email helps you grow by taking care of the ones you’ve already earned.
What makes you different from other Klaviyo/email agencies?
We don’t take a plug and play, template heavy approach. Every flow, campaign, and pop-up is custom built for your brand. You’ll get founder level strategy, weekly optimization, and a team that feels like an extension of yours, not a disconnected vendor.
What’s included in your service?
Our core offer includes full Klaviyo management, 8+ automated flows, 3-4 campaigns per week, high-converting pop-ups, ongoing optimization, and even a testimonial collection flow to drive social proof.
Is this a long-term contract?
Nope. We don’t lock you into long-term commitments. We believe in earning your trust through results. Most of our clients stick around because the ROI speaks for itself.
How fast can we get started?
Once we kick off, we’ll complete your onboarding, pop up strategy, and flow roadmap within the first 7 days and full system buildout within 30 days.
What do you need from us to get started?
We’ll need Klaviyo and Shopify access, your brand assets (logos, fonts, colors), and answers to a short brand onboarding questionnaire. That’s it—we handle the rest.
