Klaviyo Agency UK
For UK ecommerce brands, Klaviyo is the most powerful revenue channel available — but only when it’s set up correctly. Most stores leave 25–35% of their potential revenue on the table because their flows are incomplete, their segments are generic, or their templates underperform. Bambino builds and optimises Klaviyo from the ground up so your email and SMS channel becomes your most reliable, highest-margin revenue driver.
Klaviyo is not just another email marketing tool. Unlike Mailchimp, Brevo, or Omnisend, Klaviyo was built from the ground up for ecommerce — with native Shopify and WooCommerce integrations that give it real-time access to browse behaviour, cart events, purchase history, and product catalogue data. This data depth is what enables the highly personalised, behavioural flows that drive 30–40% of revenue for well-optimised UK ecommerce brands.
Most UK ecommerce businesses using Klaviyo are only capturing a fraction of its potential. They have a welcome series and an abandoned cart flow — and nothing else. They’re leaving browse abandonment revenue uncaptured, missing post-purchase upsells, failing to retain customers with win-back flows, and letting their list decay because they have no sunset process. Bambino builds the complete Klaviyo ecosystem that turns your subscriber list into a predictable revenue engine.
Our clients average 35% of total store revenue attributed to Klaviyo within 6 months. The highest-performing accounts reach 45%+. Email and SMS are the only marketing channels where the marginal cost of an additional send is near zero — making Klaviyo optimisation one of the highest-ROI investments available to a UK ecommerce business.
Most UK ecommerce stores have 2–3 flows active. The difference between a Klaviyo account generating 15% of revenue and one generating 40% is almost always the breadth and quality of the flow library. We build all 12.
Your highest-converting flow. A 3–5 email sequence that delivers your brand story, bestsellers, social proof, and a first-purchase incentive. We A/B test subject lines, send times, and discount thresholds.
The single biggest revenue recovery opportunity. A multi-step sequence targeting customers who added to cart but didn’t complete purchase. Typically recovers 8–15% of abandoned cart revenue.
Triggered when a subscriber views a product page but doesn’t add to cart. Catches intent earlier in the funnel and often outperforms abandoned cart for high-consideration categories.
Drive repeat purchases, cross-sells, and LTV. Sequences include order confirmation content, product education, cross-sell recommendations, and review requests — timed to match your delivery window.
Reactivate lapsed customers who haven’t purchased in 90, 120, or 180 days (depending on your purchase frequency). Personalised with their last purchase category and targeted incentives.
Automatically notifies subscribers who have browsed or wishlist-ed a product when its price drops. A high-converting, zero-effort flow that closes purchase intent that was previously price-sensitive.
Captures subscribers on out-of-stock product pages and notifies them the moment inventory is restored. Converts at 20–35% for high-demand products — with no paid media required.
Identifies your highest-value customers and delivers exclusive early access, priority service, and loyalty rewards. Increases repeat purchase rates and average order value for your top 10% of buyers.
Cleans your list by identifying chronically unengaged subscribers, sending a re-engagement sequence, and suppressing those who don’t respond. Protects your sender reputation and reduces Klaviyo costs.
Timed to your average delivery window, this flow prompts post-purchase reviews on your platform of choice (Google, Trustpilot, Shopify, etc.) — driving social proof that improves conversion site-wide.
Personalised birthday emails with an exclusive offer sent 7 days before and on a subscriber’s birthday. One of the highest open-rate flows in any Klaviyo account — with near-zero unsubscribe rates.
For consumable products. Timed to re-order windows based on product type and purchase history, this flow nudges customers to repurchase before they run out — dramatically reducing churn for subscription-prone categories.
A structured, revenue-focused approach to Klaviyo management — from initial audit through to continuous optimisation. No guesswork, no vanity metrics.
We audit your existing Klaviyo account (or your current email platform) to identify revenue gaps, deliverability issues, list health problems, and flow optimisation opportunities.
We develop a Klaviyo strategy tailored to your product type, purchase frequency, average order value, and customer lifecycle — prioritising flows and segments by revenue impact.
We build all flows, design on-brand templates, create segments, configure integrations, and set up GDPR-compliant opt-in forms — all tested before going live.
We run structured A/B tests on subject lines, send times, discount levels, email layouts, and CTA copy — running each test to statistical significance before drawing conclusions.
Monthly reporting on revenue attributed, open rates, click rates, conversion rates, and list growth. Continuous flow optimisation and campaign planning based on performance data.
The right message to the right person at the right time. Our segmentation approach uses purchase behaviour, engagement signals, and predictive analytics to ensure every send is relevant — protecting deliverability and maximising revenue per recipient.
Recency, Frequency, Monetary segmentation divides your list into behavioural tiers based on how recently, how often, and how much each customer has spent. RFM segments power your VIP flows, win-back flows, and campaign send strategy — ensuring your best customers are rewarded and your at-risk customers are reactivated before they churn permanently.
Klaviyo’s predictive analytics layer forecasts each contact’s next order date, expected lifetime value, and churn risk based on their historical behaviour. We use these predictions to target customers with replenishment flows before they run out, win-back campaigns before they leave, and upsell emails timed to their predicted next purchase window.
Beyond RFM, we build segments based on product category affinity, channel preference (email vs SMS), discount sensitivity, browse depth, and engagement level. These segments power both automated flows and campaign targeting — ensuring a customer who only buys from the skincare category never receives irrelevant homeware promotions.
Every Klaviyo account we manage is configured to meet UK GDPR and PECR requirements. For UK ecommerce brands, this means separate opt-ins for email and SMS, consent timestamps stored on every contact record, and automated sunset flows that delete non-consenting contacts within your defined retention period.
Under PECR, you must have explicit consent to send marketing emails and SMS to UK consumers. We configure Klaviyo’s opt-in forms with separate checkboxes for each channel, double opt-in where required, and clear consent language that meets ICO standards. Every form captures and stores consent source, timestamp, and the exact consent text shown.
Our list cleaning and sunset flows ensure that contacts who have not engaged within your retention window are automatically re-consented or suppressed — keeping your list healthy, your sender reputation strong, and your ICO compliance maintained without manual effort.
Every Bambino Klaviyo retainer covers the full stack of what it takes to drive 35%+ of store revenue from email and SMS.
Full audit of your existing Klaviyo account or migration from your current platform — covering deliverability, list health, flow gaps, segment quality, and revenue attribution accuracy.
All 12 essential flows built, configured, and tested — with personalisation tokens, conditional splits, and smart send timing tailored to your product type and purchase frequency.
Custom, on-brand email templates designed in Klaviyo’s drag-and-drop editor — optimised for mobile, tested across major email clients, and designed to drive click-through and conversion.
Removal of invalid, bounced, and chronically unengaged contacts to protect sender reputation and deliverability — ensuring your active campaigns land in the inbox, not the spam folder.
Structured A/B tests across flows and campaigns covering subject lines, preview text, send times, CTA copy, discount levels, and layout variations — with results documented and applied.
Monthly Klaviyo performance reports covering revenue attributed, flow performance by type, campaign benchmarks, list growth, deliverability metrics, and a prioritised optimisation roadmap.

Yes — Klaviyo is the leading email and SMS platform for ecommerce, and for good reason. Its native integrations with Shopify, WooCommerce, and Magento give it access to real-time purchase, browse, and cart data that generic email tools simply can’t match. For UK ecommerce brands generating £500K+ in annual revenue, Klaviyo typically contributes 25–40% of total revenue within 90 days of a full flow setup. The platform pays for itself many times over when configured correctly.
Well-optimised Klaviyo accounts typically generate 30–40% of total ecommerce revenue for UK brands. The exact figure depends on your list size, product type, average order value, and purchase frequency. Our Klaviyo clients average 35% of store revenue attributed to email and SMS within 6 months of working with us. Abandoned cart flows alone typically recover 8–15% of abandoned revenue, and welcome flows commonly achieve 20–30% conversion rates from subscriber to first purchase.
Yes — Mailchimp to Klaviyo migration is one of the most common projects we handle. We migrate your subscriber lists (with all tags and custom fields), map your existing segments to Klaviyo equivalents, recreate your email templates in Klaviyo’s drag-and-drop editor, rebuild your automations as Klaviyo flows, and validate all integrations before switching DNS records. We handle the full migration with zero downtime and no list degradation.
We configure Klaviyo with explicit opt-in consent tracking, double opt-in where required, PECR-compliant suppression lists, and automated sunset flows that suppress non-engagers before their data is deleted. All forms capture and store consent timestamps and source data. Unsubscribe requests are honoured immediately and propagated across all lists. We also configure SMS opt-in separately from email, as PECR requires independent consent for each channel.
Flows (also called automations) are triggered automatically by a specific customer action or event — a browse, an abandoned cart, a purchase, a birthday. They run 24/7 without manual intervention and are the highest-revenue, highest-ROI part of Klaviyo. Campaigns are one-time sends to a segment — sale announcements, new product launches, seasonal promotions. Both are essential, but flows typically generate 60–70% of Klaviyo-attributed revenue despite requiring no ongoing effort once set up correctly.
A full Klaviyo setup — account audit or new account setup, all 12 essential flows built, templates designed, segments created, and integrations configured — typically takes 4–6 weeks from kickoff. If you already have a Klaviyo account with some flows in place, we conduct an audit in week one and produce a prioritised rebuild roadmap. Most clients see revenue impact from the first flows going live within 3–4 weeks of starting.
Yes — we set up Klaviyo SMS for UK numbers, including the Klaviyo SMS add-on configuration, PECR-compliant opt-in flows, SMS-specific abandonment and win-back flows, and A/B tests comparing email-only vs email + SMS sequences. UK SMS open rates typically exceed 90%, making it a powerful supplement to email for time-sensitive flows like abandoned cart and flash sales. Note that UK SMS requires separate explicit opt-in from email under PECR.
