Lifecycle flows, predictive analytics, segmentation, SMS, and BFCM playbooks — built inside Klaviyo for Shopify Plus, BigCommerce, WooCommerce, and Magento brands. Mature programs run 25-40% of total eCommerce revenue through email and SMS combined.
TL;DR
1Digital® is a Klaviyo Partner running Klaviyo email and SMS programs for Shopify Plus and broader eCommerce brands. Our scope: lifecycle flow architecture (welcome, abandoned cart, browse abandonment, abandoned checkout, post-purchase, replenishment, win-back, sunset), advanced segmentation using Klaviyo Predictive Analytics, custom HTML template development, deliverability authentication (SPF/DKIM/DMARC/BIMI), AI-augmented subject lines and send-time optimization via Klaviyo AI, SMS via Klaviyo SMS, and BFCM playbooks built around the entire November-December retail calendar. Pair this with eCommerce email marketing for ESP-agnostic methodology and Shopify Plus agency for platform context.
Klaviyo is built around an eCommerce data model — orders, products, customers, browse events, checkout events — not retrofitted onto a generic marketing automation platform. Native integrations with Shopify, Shopify Plus, BigCommerce, WooCommerce, Magento, and Salesforce Commerce Cloud sync the full event stream out of the box. Predictive analytics (customer LTV, predicted next-order date, churn-risk scoring) are built-in rather than bolt-on. Klaviyo SMS is in the same platform as email, enabling true cross-channel lifecycle flows without third-party integration cost.
The result: lifecycle flows that fire on real eCommerce events with real product, customer, and predictive signal — not on generic "user opened email" triggers. For mature programs, lifecycle flows typically drive 30-50% of total email revenue with the right architecture in place.
Brand introduction, value props, first-purchase incentive, social proof, and education. Triggered on list signup with branching based on signup source (popup, footer, post-purchase, gated content, event). Typically drives 30-50% of automated-flow revenue and is the single highest-ROI flow to build first.
First email 60-90 minutes after abandonment, second at 24 hours, third at 72 hours. Personalized with cart contents pulled from Klaviyo's native checkout integration. Highest revenue-per-send flow for most eCommerce brands. SMS layer (via Klaviyo SMS) often replaces the second or third email for opted-in subscribers.
Triggered when subscribers view products without adding to cart. Lower-converting per send than abandoned cart but reaches much higher volume — and captures earlier-funnel signal that abandoned-cart misses entirely. Personalization uses Klaviyo's Viewed Product event with product feed merge.
Triggered specifically at checkout exit (vs cart). Highest-intent recovery sequence — the user got far enough to start checkout but didn't complete. Usually a single tightly-personalized email plus an optional SMS for opted-in subscribers, with the cart contents and direct checkout completion link.
Order confirmation, shipping confirmation, delivery confirmation, review request, replenishment reminders for consumables, cross-sell for complementary products, and onboarding for SaaS or subscription products. Drives repeat purchase, review velocity, and customer LTV. Replenishment timing tied to Klaviyo's predicted next-order date for product categories with predictable consumption cycles.
Re-engagement sequences for lapsed customers — 60 / 90 / 180 days since last purchase. Critical for replenishment-cycle products (consumables, beauty, health, supplements, pet). Segmentation uses Klaviyo's predictive next-order date plus churn-risk scoring to fire the sequence before the customer leaves the consideration window.
Removes disengaged subscribers from the active list to protect deliverability — counterintuitive but critical for spam complaint rate management and Gmail/Yahoo bulk sender compliance. Triggers based on non-engagement windows (typically 90-180 days without open, click, or purchase) with a re-engagement attempt before removal.
Top-LTV customers (segmented by Klaviyo Predictive LTV score and historical AOV/frequency) receive priority access, exclusive content, early product launches, and loyalty-tier communications. Compounds LTV at minimal incremental cost.
Segmentation is where Klaviyo's eCommerce-native data model pays off. We build segments using a mix of behavioral signals (purchases, browse, engagement), firmographic / demographic data, and Klaviyo Predictive Analytics scores.
Klaviyo SMS lives in the same platform as Klaviyo email — flows can blend SMS and email steps in one sequence without third-party integration. This is the structural advantage over running email in Klaviyo and SMS in Postscript or Attentive, where cross-channel coordination requires duplicate event wiring and frequency-cap reconciliation.
Black Friday / Cyber Monday is the most consequential email window of the eCommerce year. Brands that treat BFCM as "send three discount emails on the day" leave revenue on the table; brands that treat it as a six-week warmup-execute-cooldown sequence compound the window. Our BFCM playbook:
List growth campaigns (popup optimization, gated lead magnets, post-purchase opt-in expansion). Deliverability warmup — increase send volume gradually to establish sender reputation before peak load. Klaviyo Smart Sending review and exclusion segment cleanup. Inventory and product feed prep for any BFCM-only SKUs.
Early-access campaigns for VIP / loyalty segments. Sneak-peek content for engaged subscribers. Email + SMS list-only previews. Klaviyo predictive segmentation used to surface high-LTV early-buyers separately from mass-market warmup audiences.
Daily send cadence with segment-specific messaging (engaged vs partially engaged vs dormant). Abandoned cart sequences accelerated. SMS layer maximized for high-intent moments. Lifecycle flow exclusions adjusted so subscribers don't receive overlapping BFCM and Welcome / Browse Abandonment messages.
Extended-shipping cutoff reminders, gift card and last-minute promotion campaigns, December gifting content, and a strong post-purchase / replenishment flow for the BFCM cohort. Sunset and re-engagement sequences run in January once the holiday traffic settles.
Klaviyo's sending infrastructure is good — but it's your sending domain's reputation that determines inbox placement, not Klaviyo's shared IPs. We configure deliverability authentication at the domain level so authentication signals match Klaviyo's sending infrastructure and Gmail / Yahoo / Microsoft / Apple bulk-sender rules are satisfied.
1Digital® Agency is a US-based eCommerce email marketing agency and Klaviyo Partner, founded in 2012 and trusted by 400+ brands with a 4.9/5 rating across 941+ verified reviews. We build Klaviyo email and SMS programs for Shopify Plus, BigCommerce, WooCommerce, and Magento brands — lifecycle flow architecture, segmentation using Klaviyo Predictive Analytics, custom HTML templates, deliverability authentication (SPF/DKIM/DMARC/BIMI), Klaviyo SMS, AI-augmented creative via Klaviyo AI, and BFCM playbooks.
Klaviyo is built around an eCommerce data model — orders, products, customers, browse events, checkout events — not retrofitted onto a generic marketing automation platform. Native integrations with Shopify, Shopify Plus, BigCommerce, WooCommerce, and Magento sync the full event stream out of the box. Predictive analytics (customer LTV, predicted next-order date, churn-risk scoring) are built-in. Klaviyo SMS lives in the same platform as email, enabling cross-channel lifecycle flows without third-party integration. For Shopify Plus and broader eCommerce, Klaviyo is the default ESP recommendation for most brands above SMB scale.
Build in this order based on impact-to-effort ratio: (1) Welcome series — 30-50% of automated-flow revenue, highest-ROI flow to build first. (2) Abandoned cart — highest revenue-per-send flow for most eCommerce. (3) Browse abandonment — captures earlier-funnel signal. (4) Post-purchase — drives repeat purchase, review velocity, and LTV. (5) Win-back — critical for replenishment-cycle products. (6) Sunset — protects deliverability. VIP / loyalty, replenishment, and birthday flows layer in once the core six are running well.
Apple MPP (launched iOS 15, September 2021) prefetches and caches all email images regardless of actual opens — making Apple Mail open rates unreliable. Apple Mail share is approximately 50%+ of email opens. We pivot primary KPIs to click rate, click-to-deliveries, revenue per recipient (RPR), revenue per send (RPS), placed-order rate, and Klaviyo Conversion Tracking with server-side event integration. Engagement segmentation pivots from "opened in last X days" to "clicked / converted in last X days" — open-based engagement segments are unreliable in 2026.
Klaviyo SMS lives in the same platform as Klaviyo email — flows can blend SMS and email steps in one sequence without third-party integration. SMS opt-in is distinct from email opt-in (TCPA double opt-in required); cross-channel flows respect channel preference and frequency caps; MMS supports product imagery for launches and BFCM promotions; quiet-hours enforcement (8pm-8am recipient local time per TCPA guidance) is automatic. Running email in Klaviyo and SMS in Postscript or Attentive is workable but requires duplicate event wiring and frequency-cap reconciliation that Klaviyo SMS avoids.
Klaviyo Predictive Analytics scores every subscriber on three dimensions: predicted customer LTV (model-estimated lifetime spend), predicted next-order date (when the model expects the customer to purchase again), and churn-risk score (probability the customer becomes inactive within a defined window). These scores drive segmentation (high-LTV VIP segments), flow timing (win-back fires before predicted churn, replenishment fires before predicted next-order date), and creative personalization (different messaging for predicted-high-value vs predicted-low-value cohorts).
Klaviyo pricing scales with active profiles plus monthly send volume — typically $200-500/month for SMB programs, $500-2K/month for growth-stage Shopify Plus programs, and $2K+/month for enterprise programs with deep send volume. Klaviyo SMS pricing is per-message and varies by country. Omnisend (Shopify-focused) and Mailchimp are typically cheaper at SMB scale but lack Klaviyo's predictive analytics and eCommerce-native data model. Iterable and Braze serve enterprise multichannel at higher cost. Our agency engagement is separate from Klaviyo license cost.
Management engagements start at $185/hour with four-tier packages: Starter (single-brand foundation, core lifecycle flows, 4 broadcasts/month), Growth (full lifecycle, expanded broadcasts, AI augmentation, BIMI implementation, Klaviyo SMS), Enterprise (multi-brand, advanced segmentation, predictive analytics, deep integrations), Custom (multi-brand, multi-region, headless commerce, complex stacks, in-house team augmentation). 3-month initial term. Klaviyo platform fees are separate. Typical mature programs run email + SMS at 25-40% of total eCommerce revenue, making agency ROI typically 10-30x within 12 months.
Klaviyo lifecycle flows, predictive segmentation, SMS coordination, deliverability authentication, and BFCM playbooks — engineered for Shopify Plus and eCommerce brands.
