Lifecycle Email · SMS · Klaviyo Retention

Own the inbox. Own the margin.

Paid media rents attention. Email and SMS are the one channel you own outright — the audience, the data and the margin. As a certified Klaviyo agency, we turn your list into an always-on retention engine: the full lifecycle flow stack, deliverability engineered to land in the inbox, email + SMS run as one — measured on revenue, lifetime value and profit, never vanity opens.

The shift

Acquisition got expensive. The growth moved to the channel you own.

For two years brands have paid more to be seen — CAC up 40–60% since 2023, cookies and ad signal decaying, algorithms renting you ever-narrower reach. Meanwhile the cheapest growth was already on your list. Email and SMS are the only channels where you own the audience, the data and the relationship — immune to the auction, compounding instead of renting.

40–60%rise in customer acquisition cost since 2023 — paid reach you rent, not own.
£36–42returned for every £1 on email — several times paid search or social, when it's run as a system.
25–40%+of total store revenue a well-run email + SMS program should drive (mature brands reach 50%+).

These are the economics of an owned channel. RiseUp turns email into your most profitable, most measurable, most defensible source of revenue — not batch-and-blast, a lifecycle system.

Why RiseUp

Not a newsletter. A retention engine.

Most brands have the platform but not the system — a basic welcome flow, batch sends, and a list quietly decaying.

Flows are where the money is

Automated lifecycle flows earn ~18x more per recipient than one-off campaigns — around 41% of email revenue from roughly 5% of sends. We build and continuously optimise the full stack so revenue compounds while you sleep.

Email + SMS as one lifecycle

Multichannel subscribers are worth ~30% more in lifetime value. We orchestrate email, SMS and push around each customer's intent and stage from one Klaviyo data foundation — not two disconnected silos.

AI-first, run by senior humans

We score churn risk, predict next purchase and test variants at scale with AI — but strategy, brand voice and the profit number stay with a senior team. Intimate, personal-feeling email at scale.

The deliverable

The flows that do the heavy lifting.

Most brands have Klaviyo but not the system — a basic welcome and cart flow, batch newsletters, and a list quietly decaying. The money is in the full automated stack: each flow triggered by real behaviour and intent, always on, compounding. We build, sequence and continuously test the lot — and engineer deliverability (aligned SPF/DKIM/DMARC, under the 0.3% spam ceiling) so it lands in the inbox, not Promotions.

How we measure

Open rate is the easiest number to fool yourself with now.

Since Apple Mail Privacy Protection inflates and masks opens, the old metric lies. We measure the business — with the attribution and the math shown — not a vanity dashboard.

  1. Layer 01

    Email's share of revenue

    The headline number a healthy program owns — 25–40%+ of total store revenue, with mature brands past 50%.

  2. Layer 02

    Revenue per recipient

    What each send actually earns — the metric that survives MPP and tells you which flows and segments to scale.

  3. Layer 03

    LTV & repeat-purchase rate

    Retention compounding, not one-off sales — the proof the list is becoming a more valuable asset every month.

  4. The score

    Incremental profit

    Holdout/control thinking on flows so you see the lift email genuinely adds — not credit it would have grabbed anyway.

Questions, answered

Email & lifecycle questions, answered.

What does RiseUp's email marketing service actually include?

Strategy, build and ongoing optimisation of your full lifecycle program: an account and deliverability audit, list health and segmentation, the complete automated flow stack (welcome, browse and cart abandonment, post-purchase, replenishment, VIP and win-back), a campaign calendar, email plus SMS orchestration, design and copy, A/B testing, and monthly reporting against revenue and lifetime value. It's an always-on retention engine, not one-off sends — and we're a certified Klaviyo partner, so it's built on best-in-class ecommerce tooling.

How much revenue should email and SMS realistically generate for my brand?

For a well-run program, email typically drives 25–40% of total store revenue, with mature brands reaching 50%+. The biggest lever is automated flows: they can produce around 41% of all email revenue from just ~5% of sends because they earn roughly 18x more per recipient than one-off campaigns. We baseline where you are today and forecast the realistic upside from a free audit before any commitment.

We already use Klaviyo. Can you improve what we have instead of starting over?

Almost always, yes — and that's usually where the fastest wins are. Most accounts have the platform but an incomplete flow stack, weak segmentation and quiet deliverability problems. We audit your existing setup, fix what's leaking revenue, rebuild the flows properly and layer in predictive segments and SMS — keeping your list health and history intact rather than wiping the slate.

Why Klaviyo rather than Mailchimp or another platform?

For ecommerce, Klaviyo's behavioural data, segmentation, predicted customer lifetime value and native email-plus-SMS automation are in a different league — it triggers on granular actions like product views and browse behaviour, not just purchase history, and the AI and predictive tooling is built for retention. We're Klaviyo-certified and can migrate you cleanly from Mailchimp or a legacy ESP without losing deliverability or your subscriber data.

How do you make sure our emails actually reach the inbox and not spam?

Deliverability is treated as core engineering, not an afterthought. We implement the full authentication stack the 2024 Gmail and Yahoo sender rules require — aligned SPF, DKIM and DMARC, one-click unsubscribe, and BIMI where you're eligible — keep spam complaints under the 0.3% threshold through clean segmentation, and run list hygiene, re-engagement and reputation monitoring continuously so your sends land in Primary, not Promotions or spam.

How do you measure success — and how is it different from open rates?

We measure the business: email's share of total revenue, repeat-purchase rate, customer lifetime value and incremental profit, with the attribution and math shown transparently. Since Apple's Mail Privacy Protection inflates and masks opens, we treat open rate as a directional signal at best and optimise for revenue per recipient and profit instead. You always see what email genuinely adds, not vanity metrics.

Do you handle SMS and first-party data capture too, or just email?

Both — and they work better together. Multichannel subscribers are worth around 30% more in lifetime value, so we orchestrate email, SMS and push around each customer's lifecycle stage and intent from one Klaviyo data foundation. We also build consented zero- and first-party data capture into your site and flows, which becomes your most durable, privacy-safe marketing asset as cookies and ad-platform signal decline.

Isn't email old-fashioned — everyone's on social and SMS now?

Email is the highest-ROI channel in marketing — around £36–£42 back for every £1, several times what paid search or social return — precisely because it's owned, direct and measurable. It isn't competing with social; it captures the value paid and social spend so much to create. In 2026 a well-run program drives 25–40%+ of total store revenue, and we run email and SMS together as one lifecycle, not instead of each other.
