Ecommerce Email Marketing Services

Most ecommerce brands doing $1M–$50M run email at 10–15% of revenue and assume that's just where the channel tops out. It isn't. The brands getting the most out of owned channels run email at 30–40% of total revenue — same traffic, same product, same list. The gap between those two numbers is almost never the platform. It's the strategy, the flow architecture, and the execution sitting on top of it.

That gap is the entire reason these services exist. Flypost runs ecommerce email marketing services as a revenue function — not a creative retainer that ships a pretty newsletter twice a month. We're a certified Klaviyo partner, and we build email into a measurable, compounding revenue line for DTC and ecommerce brands.

What's Included

A real email marketing program is several disciplines working together. Here's the full scope — and what separates each piece done right from each piece done lazily.

Strategy and account audit

Every engagement starts with a full audit of your Klaviyo account, your existing flows, your list health, and your revenue attribution. We map where email revenue is leaking — broken flows, missing automations, segments that send to everyone, deliverability quietly suppressing your reach. The output isn't a slide deck. It's a prioritized plan tied to revenue, with the highest-leverage fixes first.

Flow buildout

Automated flows are where the compounding revenue lives — they earn while you sleep. We build and optimize the full ecommerce set:

• Welcome series — the first impression and your highest-converting flow
• Abandoned cart — recovering the revenue that's already halfway to checkout
• Browse abandonment — catching intent earlier in the journey
• Post-purchase — turning a first order into a second, and a second into loyalty
• Winback — re-engaging customers before they're gone for good
• Sunset — quietly removing the dead weight that's dragging your deliverability down

Each one properly segmented, properly timed, and A/B tested — not a default template switched on and forgotten.

Campaign management

A real campaign calendar, planned in advance and coordinated with your promotional and product calendar. Segment-by-segment send strategy so VIPs, lapsed buyers, and engaged-but-not-purchased subscribers each get the right message — not the same blast. Continuous A/B testing on subject lines, offers, send times, and content. Promotional, educational, and lifecycle-aware sends working together.

Email design

Brand-aligned, mobile-first, direct-response email design. The goal is revenue, not awards — every email is built to be read on a phone in five seconds and to drive a click. We lock a design system early so your emails look like your brand and ship fast, every week, without reinventing the layout each time.

Deliverability and list health

The work most brands ignore until their open rates fall off a cliff. We handle authentication (DMARC, DKIM, SPF), sender reputation monitoring, sunset flows, and engaged-only sending so your emails actually reach the inbox. Fixing a structural deliverability problem alone has moved the revenue number on accounts we'd barely otherwise touched. If you want to go deeper here, our DMARC and deliverability work is part of every engagement.

Reporting tied to revenue

Every report leads with revenue contribution, flow performance, and revenue per recipient — not opens. Apple's Mail Privacy Protection made open rates unreliable years ago, and an agency still leading with them is measuring the wrong thing. You'll always know what email is contributing to the business, and what we're doing to grow it.

Platforms We Work On

Klaviyo is our primary platform — it's where we go deepest, and we're a certified Klaviyo partner. It's the right answer for most ecommerce brands with real catalog complexity and serious segmentation needs.

We build on Shopify, Shopify Plus, BigCommerce, WooCommerce, and Commerce7, integrating cleanly with the rest of your stack — reviews, loyalty, subscriptions, and your store data. If you're migrating off another ESP, we handle the cutover: a clean migration with no gap in sending and a deliverability warmup plan, not a flip-the-switch-and-blast-your-whole-list gamble.

Not sure Klaviyo is even the right platform for your stage? Our guide to the best email platforms for ecommerce walks through the honest trade-offs — we put you on the platform that fits, not the one that's easiest for us.

The Flypost Process, Month by Month

Every engagement runs in roughly the same rhythm. Specifics flex with your stage and list size, but the shape holds.

Month 1 — Audit and foundations

• Full audit of your Klaviyo account, flows, list health, and attribution
• Deliverability hardening: DMARC, DKIM, SPF, sender reputation
• Migration if you're moving in from another platform
• Brand voice and email design system locked
• The first core flows live: welcome, abandoned cart, post-purchase

Month 2 — Flow buildout

• The next wave of automations: browse abandonment, winback, replenishment where your category supports it, sunset
• Segmentation strategy implemented — VIPs, lapsed, engaged, by category and purchase behavior
• First full campaign cadence running on a planned calendar

Month 3 and beyond — Optimization and scale

• A/B testing program across subject lines, offers, send times, and content
• Quarterly strategy reviews tied to revenue, not vanity metrics
• Continuous list growth and hygiene
• New flow development as your catalog and customer base evolve
• SMS layered in as a coordinated channel where it fits (more on that below)

The first 90 days are where most of the lift happens. Months 4 and on are where compounding takes over — and where email moving from a single-digit or low-teens revenue share to 30%+ stops being a projection and starts showing up in your numbers.

Pricing

We work on monthly retainers. For most ecommerce brands, our ecommerce email marketing services run roughly $2,500–$7,500/month, depending on scope — where you land in that range comes down to list size, flow complexity, campaign volume, and whether SMS and creative are bundled in.

A flows-only engagement sits at the lower end. Full-service — flows, a full campaign calendar, SMS, and design — sits at the upper end. We set your exact pricing after the audit, because quoting a number before we've seen your account is just guessing. We're transparent about the range on the first call, and if your brand is too early for what we do, we'll tell you then rather than sell you something that won't pay for itself.

Proof

The numbers below are real client results, not benchmarks pulled from an industry report.

• Linus Bikes — $270K in email revenue and a 150% sales lift. For a specialty bike brand, email became the single highest-ROI channel.
• Western Bagel — $137K in incremental revenue from email. A regional food brand turning email into a primary revenue driver, not a side channel.
• Lofi Girl and Taylor Lane Coffee — retention programs rebuilt into double-digit shares of total revenue.
• $150M+ in client email revenue generated across the portfolio.

The pattern is consistent: the retainer is the smallest line item next to the revenue it generates. You can see the full set on our case studies.

Who It's For

These services are built for DTC and ecommerce brands doing $1M–$50M+, on Shopify or Shopify Plus (or one of the other platforms above), with email that's underperforming relative to what the channel should return. If your flows are half-built, your campaigns are blasts, or email is stuck in the low teens as a share of revenue, this is exactly the gap we close.

If you're under ~$500K in revenue or your traffic is thin, an agency is probably premature — you're better served learning Klaviyo yourself first, and we'll say so. Not sure which side of that line you're on? Take the Email Marketing Fit Check — two minutes, no sales pitch, an honest read on whether you're ready and what scope makes sense.

Why Flypost

We're a team, not a solo freelancer who goes quiet when they get busy. Strategy, design, deliverability, and execution under one roof, with backup so the work never pauses. We're a certified Klaviyo partner, we measure everything against revenue, and we take deliverability seriously enough that fixing it is often the first revenue win of an engagement.

We also run SMS as a coordinated channel — email and SMS planned together so the two compound instead of cannibalizing each other or over-messaging your list.
