I help e-commerce and D2C brands generate more revenue from their email list — through high-converting automations, strategic campaigns, and data-driven segmentation built inside Klaviyo.
I'm Thangamanikandan P (Mani), an Email Marketing & CRM Specialist with 3.5+ years of hands-on experience turning email lists into revenue engines for e-commerce, skincare, and D2C brands across global markets.
My work spans the full email marketing lifecycle — from building your Klaviyo account infrastructure from scratch, to designing segmented flows that convert, to launching campaigns that consistently hit 60%+ open rates. I've generated over $47K in attributed Klaviyo revenue for a single client in one month, delivered a 1,173% revenue growth in 7 days for a skincare brand, and maintained a Klaviyo deliverability score of 96.
I don't just send emails — I engineer customer journeys that move people from first touch to loyal buyer, backed by data at every step.
End-to-end email marketing services designed to maximize Klaviyo ROI for e-commerce and D2C brands.
Full Klaviyo account configuration — integration with Shopify, custom metrics, list structure, signup forms, consent management, and property setup — done right from day one.
Build and optimize all core Klaviyo flows: Welcome Series, Abandoned Cart, Browse Abandonment, Post-Purchase, Win-Back, Sunset, and VIP journeys with advanced conditional branching.
Multi-email welcome journeys that onboard new subscribers, introduce your brand story, showcase bestsellers, and convert first-time visitors into paying customers — typically within 5–7 days.
Recover lost revenue with precisely timed, personalized sequences. I optimize send timing, urgency messaging, and product feeds to maximize recovery rates.
Re-engage high-intent visitors who browsed products but didn't add to cart — with dynamic product recommendations pulled directly from their browsing behavior.
Structured re-engagement flows that identify lapsed customers by RFM data, deliver targeted offers, and sunset truly disengaged contacts — protecting your sender reputation.
Advanced segmentation strategy built on behavior, purchase history, LTV, RFM scores, engagement tiers, and predictive analytics — ensuring the right message reaches the right person.
Full deliverability audits covering SPF, DKIM, DMARC, domain warm-up, list hygiene, bounce handling, and engagement-based sending strategies. I've maintained a 96 Klaviyo deliverability score.
Systematic testing of subject lines, preview text, CTAs, send times, content layouts, and offer structures — with rigorous analysis and documented performance improvements.
Full-service campaign management: content calendar planning, audience selection, creative briefing, scheduling, send execution, and post-send performance reporting.
The platforms and tools I use to deliver results for clients every day.
Real campaigns, real automations, and real results — each project below reflects a measurable business outcome I helped achieve.
The client was sending campaigns to lists of 19,000–21,000 recipients but struggling with inconsistent engagement. Click rates were below industry average and revenue per campaign was unpredictable. They needed a systematic approach to lift both engagement and placed-order conversion.
Across 10 sequential campaigns sent to audiences averaging ~20,300 recipients each, I managed the full build, QA, scheduling, and post-send analysis. Each campaign iterated on the last, with subject line winners carried forward and underperforming segments excluded from future sends.
Consistent, data-driven iteration — not one-off luck — is what drives sustained email performance. By treating each send as an experiment and building on the results, I delivered open rates 60%+ above industry benchmarks across every single campaign in this series.
The brand (Omar's store) needed to systematically collect Okendo product reviews post-purchase while rewarding reviewers differently based on their subscription status. A one-size-fits-all review request was generating low submission rates and untargeted reward messaging.
Built entirely in Klaviyo using property-based conditional splits. The flow checks two behavioral conditions in sequence: review history (to avoid re-requesting from existing reviewers) and subscription status (to personalize the reward). All branches are live with zero-day delay for immediacy.
A well-architected automation with smart conditional logic doesn't just save time — it creates a personalized experience at scale that generic review request tools simply can't replicate. Logic-first Klaviyo flows are where the real competitive advantage lives.
A Shopify-based client needed to understand the direct revenue contribution of email marketing. Total store revenue stood at $3,823.51 in the previous period. The goal: demonstrate measurable email-attributed growth using Klaviyo alongside Shopify analytics.
Campaigns were structured around Shopify's revenue data, with separate targeting for each product tier. Revenue was tracked across the Klaviyo–Shopify integration and compared period-over-period. Email contributed directly to the 12% revenue increase from the previous period to $4,282.74.
Email marketing isn't a standalone channel — it's an accelerant for Shopify revenue. When Klaviyo and Shopify analytics are integrated correctly, every campaign decision becomes data-informed, and attribution becomes indisputable to stakeholders.
The client's total store revenue was $116,666.10 but their Klaviyo setup was underperforming — email was contributing far below its potential. The goal was to maximize Klaviyo's attribution share and demonstrate that email could be a primary revenue driver, not just a supplementary channel.
Campaigns generated $22,752.17 (47.83% of attributed revenue) while flows contributed $24,815.10 (52.17%). Email accounted for 100% of the attributed channel. All metrics — open rate, click rate, bounce rate, unsubscribe rate, and spam complaint rate — were within or above Klaviyo's recommended ranges.
When Klaviyo is set up and operated correctly — with great deliverability, smart automation, and targeted campaigns — it can drive nearly half of a brand's total revenue. This result shows what a well-managed email channel is capable of.
MelaVie, a skincare brand focused on hyperpigmentation and radiance, needed to onboard new email subscribers with a compelling brand narrative — while driving first purchase. Their existing welcome flow was a single generic email with no personalization or urgency structure.
Created all four email templates in Klaviyo using brand-consistent design (earth tones, professional product photography, editorial typography). Embedded social proof (Vogue, Beauty features), product reviews, bestseller showcases, and skin type quiz CTAs across the series. Applied WELCOMES coupon code logic for tracking first-purchase attribution.
A welcome series should do more than say hello — it should walk a subscriber through the entire buyer journey in miniature. By structuring MelaVie's four emails around urgency, education, trust, and re-engagement, I gave the brand its best possible shot at converting cold subscribers into first-time buyers.
A skincare brand starting fresh on Klaviyo had $48,594.35 in total store revenue but $0 in Klaviyo-attributed revenue and no automation infrastructure. They needed to build from zero and demonstrate measurable impact within days.
Within 7 days: Newsletter Popup (PC) achieved 5.6% submit rate with 129 submissions. Mobile popup drove 483 submissions at 3.3%. Welcome Series generated $12,252.65 from 2,803 deliveries ($4.37/recipient). Browse Abandonment produced $1,757.60 from 470 deliveries. Abandoned Cart flow recovered $640 from 71 deliveries. Total attributed revenue reached $16,278.30 — from $0.
The fastest way to demonstrate Klaviyo ROI is to get the fundamentals right immediately — Welcome Series, Abandoned Cart, Browse Abandonment, and list capture forms. When all four launch in the same week, the compounding effect can generate four-figure revenue within days, even for a brand starting from zero.
A high-volume e-commerce store generating $269,678.35 in monthly revenue experienced a 22% total revenue decline and a 57% drop in email-attributed revenue in the tracked period (May 12 – Jun 11, 2026). The challenge: diagnose why attribution dropped and rebuild a flow + campaign strategy to recover it.
Delivered a structured performance review and optimization roadmap to the client, identifying the flow-to-campaign revenue balance as healthy but underscaled. With total Klaviyo attribution at just 2.91% of store revenue on $269K, the opportunity for email to contribute significantly more was clear. Used this dashboard as the foundation for Q3 strategy planning.
Revenue analytics isn't just about celebrating wins — it's about diagnosing declines quickly and building a roadmap to recover. When I manage a Klaviyo account, I treat every dashboard as intelligence, not just reporting. Every metric tells a story, and I make sure the client understands what it means for their next 30 days.
Feedback from brand owners and marketing leads across e-commerce, skincare, and retail.
"Mani completely transformed our Klaviyo account. Within 7 days of him rebuilding our flows and launching proper signup forms, we went from zero attributed revenue to over $16,000. The welcome series alone generated $12K. I wish I'd hired him six months earlier."
"We were skeptical that email could drive real revenue for our store. Mani proved us wrong — $47K attributed in one month, a 96 deliverability score, and zero spam complaints. His attention to list hygiene and segmentation is genuinely best-in-class."
"The campaign open rates Mani consistently delivers — regularly above 63% — are unlike anything we've seen before. He understands subject line psychology, send timing, and audience segmentation in a way that most specialists just don't. Highly recommend."
"Mani built our entire Okendo review request automation with smart conditional logic for subscribers vs non-subscribers. The flow has been running on autopilot for months and reviews have increased significantly. Exactly what we needed — no fuss, no hand-holding required."
"The MelaVie welcome series Mani created for us is stunning — both visually and strategically. It walks new subscribers through our brand story, creates urgency, and gently re-engages anyone who didn't buy. First-purchase conversion from the series exceeded our expectations."
"Mani's ability to connect Klaviyo and Shopify analytics and present it as a clear revenue story to our leadership team made him invaluable. He doesn't just execute — he explains the 'why' behind every decision, which builds trust fast. We've extended our contract indefinitely."
There are plenty of email marketers available. Here's why brands that care about results choose me.
I measure my work by revenue attributed, open rates achieved, and deliverability scores maintained — not by the number of emails sent. Every engagement starts with a clear KPI framework.
I hold both the Klaviyo Product Certificate and Klaviyo Deliverability Certificate. I don't just use the platform — I understand its architecture, edge cases, and optimization levers at a technical level.
A 96 deliverability score isn't luck — it's the result of rigorous list hygiene, SPF/DKIM/DMARC management, engagement-based sending, and bounce handling done consistently and correctly.
I approach every project with a strategic audit before any execution. Understanding your customer lifecycle, your list health, and your biggest revenue gaps comes before any flow or campaign is built.
From writing subject lines to designing templates in Figma/Canva, from configuring CRM integrations to building HTML email code — I handle the full email production cycle without external dependencies.
I work with clients across the USA, UK, Canada, and Australia — across all major time zones. You'll always receive updates, reports, and responses within agreed windows, with full transparency on every project.
