Shopify Email Marketing Agency

Shopify Email Marketing done right is 30–40% of revenue on a mature DTC brand. Under 20% means flows are missing or under-powered; 40%+ means the program is working. Anything in between is addressable with a proper audit and rebuild.

The common pattern when we inherit an email program: the 7 DTC-critical flows exist on paper but half are broken (welcome without the promised discount code, abandoned cart missing the product image, post-purchase that stops after day 3), list hygiene hasn't run in six months so bounces drag down sender reputation, campaigns have drifted into "we haven't sent in a while" territory, and deliverability infra (SPF, DKIM, DMARC, BIMI) was configured once and never reviewed.

Our Shopify Email Marketing engagement model:

• 4-week audit ($6k–$12k fixed) — flow inventory, segmentation review, deliverability infra check (SPF/DKIM/DMARC/BIMI, Google Postmaster reputation, subdomain separation), list health review, campaign cadence analysis. Output: a written roadmap ranked by effort + revenue impact.
• Monthly retainer post-audit ($4k–$15k/mo) — flow repair, new flow builds, campaign calendar + content, ongoing deliverability, list hygiene, monthly reporting against MER contribution.
• Integrated retainer ($12k+/mo) — email as part of a full-funnel retainer with Shopify Marketing Agency or Shopify PPC Agency. One measurement stack, one contribution-margin number.

Team shape: named email strategist on kickoff, named copy lead, named designer for template builds. Not a rotating pool.

A Klaviyo Agency for Shopify should know Klaviyo's edge cases, not just its happy path. Klaviyo is the default for serious programs — best segmentation, best flow logic, deepest Shopify data feed, strongest deliverability tools — but it's powerful enough to misconfigure.

What we ship as a Klaviyo agency:

• Segmentation architecture — behavior-driven (engagement, purchase history, product category, season) over demographic. Narrow segments with high relevance beat broad blasts. We build 15–25 core segments that drive 80%+ of sends.
• Flow builds + repair — welcome, browse abandon, cart, checkout abandonment, post-purchase, winback, replenishment, VIP, reactivation, birthday, back-in-stock, price-drop. Each tuned to your catalog + customer lifecycle.
• Custom data feeds — Klaviyo's Shopify integration covers the basics; custom events for subscription lifecycle (ReCharge), loyalty (Smile/LoyaltyLion/Yotpo Loyalty), review-triggered flows (Yotpo/Okendo), and B2B-specific triggers on Shopify Plus.
• Deliverability infra — SPF/DKIM/DMARC configured and monitored, BIMI once DMARC is enforced, subdomain separation (transactional vs. marketing), list hygiene via engagement-based suppression, sender reputation monitored in Google Postmaster.
• Campaign calendar + content — 2–3 campaigns/week for most brands, 4–6 for high-cadence. Each campaign has a reason (product, story, educational, social proof, offer) — no "we haven't sent in a while."
• A/B testing framework — subject lines, hero imagery, CTA copy, send-time optimization. Winners become defaults in the flow library; losers retired.

Klaviyo vs Shopify Email vs Omnisend honest take: Klaviyo for serious programs, Shopify Email for low-cadence brands (1–2 campaigns/month), Omnisend as middle ground. We've migrated from all three to all three; choice is use-case fit, not vendor preference.

The 7 Shopify Email Flows every DTC store should ship, in priority order:

1. Welcome — subscriber to first purchase. Incentive, brand story, first product highlight, case for order #1. Broken welcome flows are the single most common issue we audit.
2. Browse abandonment — viewed without adding to cart. Softest trigger; lowest send rate; catches interest before it fades.
3. Cart abandonment — added to cart, didn't check out. Highest-performing flow for most brands. Product image, incentive, urgency timer.
4. Checkout abandonment — reached checkout, didn't complete. Most urgent trigger; usually a reminder + slight friction reduction.
5. Post-purchase — shipping updates, care instructions, review request, referral enrollment, cross-sell at the 30-60 day mark. LTV-building window.
6. Winback — lapsed customer, no purchase in X months. Segmented by prior behavior (VIP vs. single-purchase), not one-size-fits-all.
7. Replenishment — predictable-cadence products (consumables, supplements, skincare). Triggers on expected repurchase window.

Beyond the core seven: VIP flow (high-LTV segment with exclusive access), reactivation (specific campaign-triggered), birthday + anniversary, back-in-stock, price-drop. Each earns its place in a mature program with measurable contribution.

Our Shopify Email Flows build process: audit existing flows for breakage, repair the broken ones first (fastest-ROI work), build missing flows in priority order, instrument each flow with UTM tags and Klaviyo attribution, measure contribution margin per flow monthly, iterate winners.

Shopify SMS Marketing works when the unit economics pencil out — and it breaks even or worse when they don't. SMS revenue is real; SMS cost is real ($0.01–0.03 per send depending on provider + carrier). Deliverability shrinks over time if list health deteriorates. Some brands get 10%+ of revenue from SMS; others should not run it.

We audit every brand's SMS unit economics before scaling: cost per send + deliverability + opt-out rate vs. incremental revenue. Brands that pass: visual products, impulse categories, flash-drop-driven launches, loyalty-program-heavy brands. Brands that fail: considered purchases with long decision cycles, high-margin niche products where frequency pushes opt-outs faster than conversions.

Vendor choice on Shopify SMS:

• Postscript — best integration with Klaviyo + Shopify for most brands. Strong Shopify data feed, solid segmentation that mirrors Klaviyo patterns, reasonable pricing.
• Attentive — more B2B-style account management, enterprise-fit features, higher price point. Right for brands past $20M GMV with dedicated SMS team.
• Klaviyo SMS — Klaviyo's own SMS, same platform as email. Simplifies the stack if already Klaviyo-heavy; less SMS-specific optimization than Postscript or Attentive.

SMS program components we run: welcome flow (opt-in + incentive), cart abandonment (urgent + concise, SMS-appropriate), campaign sends (2–4/month typical, aligned with email calendar), post-purchase touchpoints, VIP segment sends, list growth via pop-up + checkbox + keyword campaigns.

Deliverability best practices: carrier compliance (opt-in keywords, opt-out response, frequency caps), list hygiene (no-engage suppressions at 90 days), segment cadence caps to prevent over-messaging, monitoring deliverability rates per carrier for anomalies.
