What we do

One channel. Done properly.

We don't do TikTok, SEO or brand films. We do Klaviyo email for e-commerce — that focus is why it works.

How we work

From audit to revenue in four steps.

No mystery retainers. Every engagement starts with a free audit, so you can judge the thinking before you spend a pound.

  1. 01

    Audit

    We review your Klaviyo account against 20+ checkpoints and show you exactly where revenue is leaking. Free, no strings.

  2. 02

    Roadmap

    You get a prioritised plan — what to fix first, what it's worth, and how long it takes. Keep it or have us build it.

  3. 03

    Build

    We write, design and launch your flows and campaigns inside your account. You see everything before it goes live.

  4. 04

    Optimise

    Monthly testing and plain-English reporting on the only metric that matters: revenue per subscriber.

Why CueSend

Specialist beats generalist. Every time.

Full-service agencies treat email as an add-on. For us it's the whole job — which changes the quality of everything you receive.

  • Klaviyo-only, e-commerce-only

    We work in one platform for one type of business. Less ramp-up, fewer mistakes, faster builds.

  • Senior attention on your account

    Your account isn't handed to a junior after the sales call. The person who audits your account is the person who does the work.

  • Results-led, jargon-free reporting

    We report on revenue per subscriber and what we're doing to grow it — not vanity opens dressed up as progress.

  • Rolling monthly terms

    No 12-month lock-ins. We keep clients by performing, not by contract.

FAQ

Questions, answered straight.

What is the free email audit, exactly?

We go through your Klaviyo account against 20+ checkpoints — flows, campaigns, segmentation, sign-up forms and deliverability — and send you a short, prioritised report of what's costing you revenue and how to fix it. No call required, no obligation to work with us afterwards.

Do you only work with Klaviyo?

Yes — deliberately. Klaviyo is the strongest email platform for e-commerce, and specialising in one tool means we build faster and to a higher standard than generalist agencies. If you're on another platform, we can handle the migration too.

How quickly will we see results?

Core flows typically start producing revenue within days of going live, because they target the highest-intent moments — people abandoning checkout, first-time buyers, lapsed customers. Campaign and list-growth gains compound over the following two to three months.

Do you lock clients into long contracts?

No. We work on rolling monthly terms after an initial setup period. If we're not earning our fee, you shouldn't be paying it — it's that simple.

We barely send any email at the moment. Is it too early?

If you have a store and any list at all, it's not too early — email is usually the cheapest revenue you're not collecting. The audit will tell you honestly whether there's enough to work with yet.

Do you only work with UK brands?

No — we're based in the UK, but we work with e-commerce brands anywhere. Email doesn't care about time zones, and the audit works the same whether your customers are in Manchester or Melbourne.
