Buffyellow

The channel that lowers your CAC every time a customer comes back.

Paid ads acquire customers. Email keeps them — and turns one purchase into a relationship. We set up and manage Klaviyo exclusively for NZ ecommerce brands, built around your product catalogue, your customer segments, and your margin structure.

Have Klaviyo, not using it well

Your list is bigger than your results.

You've got subscribers — maybe even a decent list size — but email is contributing less than it should to your store revenue. Flows were set up once and left alone. Campaigns go out when someone remembers. There's no real segmentation, no clear strategy around your product catalogue, and no way to know what's actually working. We'll audit your Klaviyo account and show you what a properly structured setup looks like — no obligation to work together.

You want to build it properly from the start.

Starting email with a small list is actually an advantage — you can build the right habits before bad ones form. We'll set up your Klaviyo account correctly, connect it to your Shopify or WooCommerce store, build the core automated flows, and put a list growth strategy in place so the asset compounds over time. Email built right from day one pays dividends for years.

Starting from scratch

Our Methodology

How we build your email system.

Email isn’t a broadcast channel — it’s a retention system. Every step we follow is designed around ecommerce stores on Klaviyo, built to work with your product catalogue and customer behaviour, not against it.

01

Audit your Klaviyo account & list health

We start by reviewing your existing setup — account configuration, flow structure, suppression lists, deliverability metrics and engagement rates. A poorly maintained list quietly destroys sender reputation and inbox placement. We find the gaps before we build anything new.

02

Fix deliverability & sender reputation

Deliverability is the foundation nobody talks about. We verify your domain authentication (SPF, DKIM, DMARC), clean suppression lists, warm domains where needed, and ensure your emails are landing in inboxes — not spam folders — before any campaigns go out.

03

Build & optimise your core automated flows

Flows are the engine of email revenue — they run 24/7 without manual effort. We build and optimise the flows that matter most for ecommerce: welcome series, abandoned cart, browse abandonment, post-purchase, and win-back — each tailored to your product catalogue and customer journey.

04

Segment your list by behaviour & purchase history

Sending the same email to your entire list is one of the fastest ways to damage deliverability and erode engagement. We build segments based on purchase behaviour, product category affinity, order frequency, and lifetime value — so every send reaches people it's relevant to.

05

Plan & execute a calendar-driven campaign strategy

Campaigns complement flows by staying top of mind with your active list. We build a campaign calendar around your product releases, seasonal moments, and promotional strategy — with clear criteria for send frequency, segment selection, and what to measure after each send.

06

Report on revenue contribution & list growth

Monthly reporting on email-attributed revenue, flow performance, campaign open and click rates, and list growth. We focus on what email is contributing to LTV and blended CAC — not just open rates that look good but don't connect to profit.

Two Workstreams

Flows do the work.
Campaigns stay top of mind.

A complete email programme for an ecommerce brand has two distinct layers. Both matter — but they serve different purposes and run on different rhythms.

Always on. Always working.

Triggered by customer behaviour. Set up once, optimised over time.

Intentional. Timely. Relevant.

Sent to segmented lists around your store’s calendar and product moments.

How We Measure It

The numbers email is actually moving.

Open rates and click rates are useful signals — but they don’t tell you if email is making your store more profitable. These five numbers do. Every email decision we make connects back to at least one of them.

01

CAC

Email lowers blended CAC every time a customer returns without a paid click

02

Conversion Rate

How well your flows and campaigns convert subscribers into buyers

03

AOV

Cross-sell and post-purchase flows directly lift average order value

04

Contribution

Email revenue at near-zero variable cost — highest contribution margin of any channel

05

ltv

The primary lever email moves — repeat purchases compound customer value over time

What to Expect

Honest about how email works.

Email is one of the highest-ROI channels available to an ecommerce brand — but it doesn’t work like paid ads. The returns are slower to start and faster to compound. Here’s what working with us actually looks like.

List quality matters more than list size

A list of 2,000 engaged, segmented subscribers will outperform a list of 20,000 unmanaged ones every time. We focus on building and maintaining a healthy list — because sending to the wrong people damages deliverability and kills long-term performance.

Flows do the heavy lifting — campaigns keep momentum

Most of the revenue from a well-run email programme comes from automated flows, not campaigns. We get the flows right first — because they compound silently in the background while everything else is being built.

The real return shows up in your blended numbers

Email's biggest contribution isn't always visible in Klaviyo alone. It shows up in lower blended CAC, higher LTV, and more profitable paid acquisition — because returning customers acquired through email cost nothing to reacquire. That's what we track and report on.

No lock-in contracts

Month-to-month. Leave any time.

You own the account

Always. No handover issues.

No hidden fees

One flat management fee. That's it.

Direct access

You talk to the people doing the work.
