Klaviyo agency · Shopify email marketing

An ecommerce email marketing agency that drives attributed revenue — not just sends emails.

Hetoli Marketing is a specialized Klaviyo and Shopify email marketing agency for DTC brands. We build and operate the automated flows, weekly campaigns, and segmentation strategies that recover abandoned carts, increase repeat purchase rate, and grow customer lifetime value. You pay $2,000/month base plus 10% of attributed email revenue.

What is an ecommerce email marketing agency?

An ecommerce email marketing agency is a specialized partner that runs your entire lifecycle email program — flows, campaigns, design, segmentation, and analytics — on platforms like Klaviyo, Mailchimp, Omnisend, or Shopify Email. For most DTC brands, email is the single highest-ROI marketing channel, often returning 30× to 50× spend.

At Hetoli Marketing, our Klaviyo agency service covers the full ecommerce retention stack:

  • 6+ automated flows (welcome, browse abandon, abandoned cart, post-purchase, replenishment, win-back, VIP, sunset)
  • Weekly campaign sends to active and engaged segments
  • On-brand email design and copywriting
  • Behavioral segmentation and predictive audience building
  • A/B testing on subject lines, copy, design, send time
  • Revenue attribution dashboard with daily reporting
  • Deliverability monitoring and list hygiene

The deliverable is simple: more revenue from your existing customer list. Better email economics, higher repeat purchase rate, more lifetime value per customer.

Who we're a fit for

Our ecommerce email marketing agency works best with DTC brands that have:

  • $30K+ monthly revenue — enough volume that 10% revenue lift covers the retainer with room to spare.
  • An existing customer database — at least a few thousand email subscribers and order history for segmentation.
  • Klaviyo, Mailchimp, Omnisend, or Shopify Email — or willingness to migrate.
  • A recognizable brand identity — visual style, tone of voice, customer language we can preserve.

If that's you, our Shopify email marketing service can typically lift attributed email revenue by 2–4× within 90 days — usually paying back the retainer in the first month through cart recovery alone.

Common clients include apparel, beauty, supplements, home goods, accessories, and food & beverage DTC brands.

What's included

Everything our Klaviyo agency builds and runs for you.

Most ecommerce email tools give you a software seat and a tutorial library. We deliver an entire retention program — designed, built, optimized, and reported.

01Audit

Klaviyo & Shopify account audit

We audit your existing Klaviyo (or Mailchimp/Omnisend) account to map current flows, segments, deliverability metrics, and revenue attribution. Most accounts have 30–50% revenue upside hiding in broken flows, missing segments, and stale templates.

02Flows

Six core automated flows live in 30 days

We build (or rebuild) the six flows that drive 80% of email revenue: welcome series, browse abandonment, abandoned cart, post-purchase / thank-you, win-back / sunset, and replenishment (for consumable products). Additional flows like VIP, birthday, and product-back-in-stock layered on month two.

03Campaigns

Weekly campaign sends & calendar

A monthly content calendar mapped to your product launches, promotions, holidays, and brand stories. We design, write, and schedule weekly campaigns to engaged subscribers — typically 4–6 sends per month, segmented by purchase behavior, lifecycle stage, and engagement.

04Design

On-brand email design & copy

Our designers and copywriters create modular email templates that match your brand identity. Mobile-first design, accessible color contrast, branded visuals. Copy that reads like your brand voice — not a template. Approved templates become reusable building blocks for fast campaign turnaround.

05Segmentation

Behavioral segmentation & predictive audiences

We build smart segments based on RFM (recency, frequency, monetary), product affinity, lifecycle stage, predicted gender, and engagement. Klaviyo's predictive audiences (CLV, churn risk, next-order date) get layered on for advanced targeting. Better segmentation drives 3–5× higher revenue per send.

06A/B Testing

Subject lines, copy, design & send time testing

Every campaign and flow includes A/B tests on the variables that move revenue: subject lines, preview text, hero image, CTA copy, send time, and segment targeting. We document winning patterns and apply them across the program. Continuous compounding.

07Attribution

Revenue attribution dashboard

A custom dashboard that tracks attributed email revenue daily — by flow, by campaign, by segment. We report on % of total revenue from email (the industry benchmark is 25–35% for mature DTC brands), revenue per recipient (RPR), and revenue per send. You always know what's earning its keep.

08Deliverability

Deliverability monitoring & list hygiene

We monitor inbox placement rates, complaint rates, and unsubscribe rates weekly. Disengaged subscribers move to a sunset flow, then get pruned to protect sender reputation. Suppression lists managed. SPF, DKIM, DMARC, and BIMI configured for maximum inbox placement.

30-day launch timeline

From kickoff to first attributed revenue in 30 days.

Ecommerce email marketing ramps faster than cold email because there's no warm-up phase. Most clients see meaningful attributed revenue within the first two weeks.

Week 1 / Audit

Account audit & strategy

90-minute kickoff call. Klaviyo audit, brand and voice intake, product catalog review. Strategy doc and 30-day roadmap delivered.

Week 2 / Build

First three flows live

Welcome series, abandoned cart, and browse abandonment flows designed, built, tested, and turned on. Templates created for campaign use.

Week 3 / Expand

Remaining flows + first campaigns

Post-purchase, replenishment, and win-back flows built. First two campaign sends to engaged segments. A/B tests in flight.

Week 4+ / Scale

Optimize & report

Attribution dashboard live. Weekly campaigns running. Monthly strategy review. Winning tests rolled into the program.

Ecommerce email pricing

Performance pricing aligned to your revenue.

Most Klaviyo agencies charge $3,000 to $10,000 per month flat — whether they grow your email revenue or not. Hetoli Marketing charges a smaller base, plus a percentage of attributed email revenue. We make more when you make more.

$2,000
/ month base retainer
+ 10% of attributed email revenue

What's included in the $2,000/month base

  • Klaviyo (or Mailchimp/Omnisend) audit and strategy

10% of attributed revenue

You pay 10% of email-attributed revenue as reported by Klaviyo (or your ESP) using the platform's native attribution. Attribution window is the platform default — typically 5-day click + 0-day view for Klaviyo. The number is auditable in your own account; we use your dashboard as the single source of truth.

Minimum commitment is 90 days, then month-to-month with 30 days' notice. Most clients see the retainer paid back in the first month through abandoned-cart recovery alone.

Klaviyo agency FAQ

Ecommerce email marketing FAQ.

A senior ecommerce email marketer costs $90K–$150K/year salaried. A Klaviyo agency gets you a full team — strategy, design, copy, deliverability, analytics — for less than half that, with no benefits, no recruiting, and no ramp time. The trade-off is shared attention; you're one of multiple clients, not a dedicated employee.
For most DTC brands with under-built email programs, yes. The lift comes from filling gaps — brands typically have 1–2 flows live and send sporadic campaigns. We add 4–6 missing flows, weekly campaigns, segmentation, and A/B testing. The math works out to 2–4× attributed revenue within 90 days for almost every client. Brands already running mature email programs see smaller (10–30%) lift.
Yes — we handle Klaviyo SMS and Postscript SMS as add-ons. SMS is one of the highest-ROI ecommerce channels but requires careful compliance (TCPA in the US, GDPR in the EU). Pricing is an additional $500/month + 10% attributed SMS revenue.
We work with Klaviyo (preferred), Mailchimp, Omnisend, Drip, and Shopify Email. If you're considering migrating, we can manage the migration as part of onboarding (additional one-time fee). Klaviyo is generally worth migrating to for any DTC brand doing $50K+/month — the segmentation, predictive analytics, and Shopify integration are best-in-class.
Not if your sender reputation is healthy. We monitor inbox placement weekly and use list hygiene practices (sunset flows, suppression list management, engagement-based segmentation) to keep deliverability above 95%. We also configure SPF, DKIM, DMARC, and BIMI for maximum trust.
Yes. You always have full Klaviyo access. Our attribution dashboard pulls from Klaviyo and updates daily. Monthly performance fee invoices reference Klaviyo's reporting directly — auditable on your end.
