Klaviyo email marketing
for ecommerce businesses
that want to grow

RTN® builds and manages the automated email flows and campaigns that turn your website traffic into repeat revenue. Welcome sequences, abandoned cart recovery, post-purchase follow-ups — all running 24/7 without you touching it.

Most ecommerce email is either neglected or wasted

You installed Klaviyo months ago. Maybe you sent a few campaigns early on. But the automated flows never got built properly, the welcome sequence is either basic or missing entirely, and abandoned carts are just walking out the door with your money.

Or you are sending emails, but without a clear strategy. Random campaigns with no segmentation. The same message going to everyone on your list regardless of what they bought, browsed, or ignored. Open rates declining. Unsubscribes creeping up. Revenue from email stuck at a fraction of what it should be.

The common thread is the same problem we see in paid ads accounts: no structure, no strategy specific to your business, and no one actively managing it. Klaviyo is a powerful platform, but it does nothing useful on its own. It needs someone building the right flows, writing the right emails, and sending them to the right people at the right time.

What RTN does differently

Performance marketing through a different channel

We approach email the same way we approach paid ads: with data, structure, and a focus on revenue. Segmentation, targeting the right person at the right time, optimising for measurable outcomes. Klaviyo is the standard email platform for ecommerce because it integrates directly with your store, pulls in all your product and customer data, and lets us build automated flows based on what your customers actually do on your site.

Your ads data feeds your email strategy

This is where working with a PPC agency on email makes a genuine difference. We already know which products convert from paid traffic, where people drop off, and which audiences respond to what messaging. That data directly informs the email strategy. We are not guessing which products to feature in campaigns or which segments to prioritise. A standalone email agency starts from scratch. We start from insight.

We handle the whole thing

Strategy, setup, email content, design, segmentation, and ongoing optimisation. You do not need to learn Klaviyo, write emails, or manage campaigns. We build the automated flows that run in the background generating revenue, and we handle the regular campaign sends that keep your list engaged and buying.

No lock-in

RTN works on rolling 30-day terms from day one. No setup fees hidden in long contracts, no 12-month lock-ins. If we are not delivering, you leave. The flows and templates we build are yours to keep.

The RTN® process for Klaviyo

The same structured, data-driven approach we apply to paid ads, adapted for email. Four phases, clear deliverables at each stage, and full transparency on what we are doing and why.

PHASE 1

Audit

We audit your existing Klaviyo account, review your ecommerce platform integration and data flow, analyse customer purchase patterns and site traffic, and identify the quick wins that will make the biggest impact first.

PHASE 2

Strategy & Build

We build the core automated flows: welcome series, abandoned cart recovery, browse abandonment, post-purchase sequences, and win-back campaigns. Email templates designed to match your brand. Segments and suppression rules configured properly.

PHASE 3

Launch

Flows go live. We monitor deliverability, open rates, and click-through rates closely in the first weeks. Domain authentication and warm-up handled if needed. First campaign emails go out to your segmented list.

PHASE 4

Optimise

Ongoing campaign management, A/B testing on subject lines and timing, segmentation refinement, seasonal campaign planning. Monthly performance reports showing revenue attributed to email, flow performance, and what we are testing next.

Frequently asked questions

How much experience do you have with Klaviyo?

We work with ecommerce businesses every day. Klaviyo is the standard email platform for ecommerce because it integrates directly with WooCommerce and Shopify, pulls in all your product and customer data, and the flow logic is the same strategic thinking we apply to PPC campaigns. Segmentation, targeting the right person at the right time, optimising for revenue. It is performance marketing through a different channel.

Can I just set up Klaviyo myself?

You could set up basic flows yourself. Klaviyo has templates. But the difference is in the strategy: knowing which flows to prioritise, how to segment properly, what timing works, and then actually keeping on top of it month to month. Most business owners set it up, send a few emails, then it goes quiet. That is where the revenue leaks.

What ecommerce platforms do you work with?

Klaviyo integrates natively with WooCommerce, Shopify, Magento, and BigCommerce. We handle the integration setup and data flow verification as part of the onboarding process, regardless of which platform you are on.

How quickly will I see results?

Automated flows typically start generating revenue within the first month of going live. Abandoned cart recovery is usually the fastest win. Full impact builds over 2-3 months as we optimise flows, refine segmentation, and build out campaign strategy based on real performance data.

Do I need to already have Klaviyo installed?

No. If you are starting from scratch, we handle the full setup: account creation, platform integration, domain authentication, and list migration if you are moving from another provider. If you already have Klaviyo installed, we audit what is there and build from it.

Are there any long-term contracts?

No. RTN works on rolling 30-day terms. No 12-month lock-ins, no cancellation penalties. If we are not delivering, you can walk away. Everything we build in your Klaviyo account stays with you.
