Expert insights on email marketing, SMS strategies, and ecommerce growth to help scale your business
Set up Claude Code with Klaviyo in about 10 minutes using our free starter repo, then ask it what Klaviyo's interface can't answer quickly: why a welcome flow tripled its sends, who your top customers are in one city, and which sale made the most money.
Between two purchases, the typical repeat customer receives about 17 emails and clicks 0 or 1. Half of repeat purchases happen with no email click at all, and open data can't say how many were read. Customer-level data from 5 DTC brands on Klaviyo.
September 2026 benchmarks from 9 e-commerce brands and 6.3M emails. Email revenue rose 5.6% while store revenue fell 9.1%, lifting email attribution to 33.7%. Campaign revenue grew 10.3% on 9.0% fewer sends, and the biggest sender reversed August's volume surge.
A subscription brand's Klaviyo account marked customers active or cancelled, and 63% of the "active" ones had actually cancelled, some two years earlier. The integration sent the cancellation event but never updated the profile property. How we reconciled about 28,000 profiles against the client's data warehouse with Claude Code: a negative match, email then name-and-ZIP fallbacks, verification before any write, and the flow plus weekly job that keeps it from drifting again.
I saw a shoppable lookbook in a brand's email and rebuilt it with Claude Code as one Shopify section file: click a look, pick a size, add to bag without leaving the page. What Claude Code handled, the three prompts behind the build, how it stays portable across themes, and deep links that open a specific look from an email. The code is free on GitHub.
A Klaviyo popup targeted only at existing email subscribers who have not opted into SMS converts at 5.09% across four brands in our portfolio, roughly four times a standard on-site signup popup. It is one targeting dropdown that almost nobody turns on.
August 2026 benchmarks from 10 e-commerce brands and 7.2M emails. Email revenue rose 14.7% to $791K and every dollar of the gain came from flows: flow revenue +45.5% while campaign revenue slipped 4.2% on 39% more sends. The flow multiplier snapped back from 12.7x to 20.9x.
An eight-week case study from a real Klaviyo account: after a domain migration, we cut standard sends from 68K to 36K recipients, opens went from 27% to 38%, and revenue per recipient held flat. The layered core audience (engaged OR recent buyer OR recent browser), the provider-scoped exclusion that lifted Gmail opens 7 points at zero revenue cost, and the from-address mistake that bounced 24% of one send's Gmail volume.
Suppression blocks mail until any tool with an API key removes it. Unsubscribing revokes consent, works on never-subscribed profiles, and no suppression call can reverse it. We tested the whole path on a live account: the endpoint, the activity-log quirk, and the one honest caveat about what can still bring a profile back.
For a subscription-heavy brand on Shopify Plus, we replaced Rebuy with cross-sell blocks we built into the native checkout and the theme cart drawer: curated offers, family exclusion, size preselection, one-tap adds. Every add stamps hidden line properties (surface, anchor, slot, size behavior), so the order carries its own attribution. After five and a half weeks: a 3.6% take rate on 113 cross-sold orders, cart and checkout pulling equal weight, size preselection right 96% of the time, and 17% of cross-sold lines switched to a subscription, the number no app dashboard could ever show this store.
Every one-time item in this Plus checkout carries a live "Switch to Subscription & Save $X" card that swaps the variant in place, on the native checkout page. The store has no selling plans and no subscription app, which is why we couldn't get this out of Rebuy even paired with one: billing lives in an external backend and "subscription" is just a variant. One checkout UI extension, one updateCartLine call, real savings from live prices, and attribution stamps that survive the swap. 4 of the first 9 cross-sold orders used it.
Jarvis is the internal AI account manager we run our agency on: a living dossier per client, connected to Asana, Slack, email, call transcripts, and every Klaviyo account. Three real examples from one client: it built the layered campaign audience that cut sends 47% while opens went from 27% to 38%, it caught mislabeled sends and a lapsed test decision, and it produced the scored strategy report, every number pulled live from the API.
Sender reputation is scored per inbox provider, so when Gmail and Yahoo open rates lag on an otherwise healthy account, shrinking your whole send punishes providers that were never the problem. The fix is an exclusion segment scoped to the problem providers: unengaged Gmail and Yahoo profiles sit out every other send while everyone else gets mail as usual. We built it with Claude Code in minutes, straight into the account via the API. Updated with three weeks of results: Gmail opens up 7 points, Microsoft bounces cut 4x, revenue per send higher on treated campaigns.
klaviyo-cli is a free, open-source command line interface for Klaviyo: 32 commands covering campaigns, segments, flows, profiles, events, and metrics. We run it across 12 client accounts almost daily; audience builds that took 10-15 minutes now take about 20 seconds. And deletes are blocked at the transport layer, so an AI agent with a live API key cannot destroy subscriber data.
Sunset flows have a blind spot: the people you suppressed who come back and start browsing again. Klaviyo will never email them unless someone reverses the suppression, and nobody is watching for that. This flow watches for it. One segment, one webhook, and aggressive list cleaning becomes safe.
Design the page in Figma, hand the mock-up to Claude Code inside the Shopify theme repo, and it builds the page as native Liquid blocks: reusing what the theme already has, pulling its own assets via the Figma API, and fixing visual bugs from screenshots. Hands-on time is a few minutes.
July 2026 benchmarks from 12 e-commerce brands and 5.6M emails. Campaign revenue held flat on 20% fewer sends (RPR +25.3%) while flow revenue fell 27.4%, compressing the flow multiplier from 25.9x to 12.4x. This month's read: smaller, sharper campaign sends against a flow-side seasonal trough.
We ran Orita on an eight-figure brand for six weeks. Click rate jumped 31% and Klaviyo made the strategy look nearly free. We still turned it off: opens fell, and Google Analytics and Shopify said real revenue was leaving. Updated September 2026: the client kept Orita in a second role through the summer, then ended the contract. Full winback and resend numbers inside.
The difference between generic AI email copy and drafts that are nearly sendable is three layers of context: a brand voice profile built from your site, your full Shopify product catalog, and real copywriting instruction packaged into a skill. Plus one step most people skip: briefs generated from your Klaviyo campaign data.
A client sent a 1,600-contact do-not-solicit list that needed to be removed from Klaviyo. An AI agent with Klaviyo API access matched every email, found the 200 still emailable, suppressed them, and produced a per-contact audit. The interesting part isn't the speed, it's the verification.
June 2026 benchmarks from 13 e-commerce brands and 8.1M emails. Campaigns cooled off the seasonal peak (email revenue down ~20% to $1.00M) but flows held their ground, lifting the flow multiplier to 22.1x. This month's read: what a portfolio looks like when the promo blasts quiet down.
May 2026 benchmarks from 12 e-commerce brands and 9.5M emails. Campaigns retook the revenue lead from flows on a grilling-season surge, total email revenue jumped 36% to $1.23M, and the flow multiplier compressed to 20.1x.
Per-flow conversion, open, click, and revenue-per-recipient benchmarks across 14 ecommerce brands over the trailing 365 days. Welcome (4.37%), abandoned checkout (2.30%), abandoned cart (1.82%), browse (0.61%), and the rest — with the per-brand spread that pooled averages hide.
Most ecommerce popups collect only an email. Adding one intent question — three to five radio buttons — populates a Klaviyo profile property that powers welcome flow splits, targeted campaigns, abandoned cart personalization, and aggregate customer insight.
Two jewelry brands in our portfolio average $2,582 and $46 per order — which is why AOV-by-industry benchmarks are useless. AOV cut by subscriber status, repeat behavior, and email attribution across 209K orders from 15 DTC brands, plus why the average AOV number lies.
We turn Klaviyo Smart Sending off in every flow we build. The most common audit finding: Smart Sending left on for the abandoned checkout flow — silently suppressing the highest-converting email in the account to protect campaigns that convert at a fraction of the rate.
Most replenishment flows fail because the timing is a guess. Here's how to pull real days-between-repeat-orders out of Klaviyo, the email cadence that fits a consumable buying cycle, the discount math that decides whether your reorder offer is worth running, and the full build (no Smart Sending).
Generic email is dead — the mass-broadcast model is on borrowed time. Here's the bet we're making about where retention is heading, and the tool we built (SendPersonal) to act on it.

Open rate: 54%. Click rate: 4.5%. CTOR: 8.2%. The brand sending 18 emails/month has better engagement than brands sending 2. Benchmarks from 83M emails across 16 DTC brands.
At the typical DTC brand the top 20% of customers drive ~56% of revenue (median Gini 0.52) — the 80/20 rule overstates concentration for most brands. Per-brand benchmarks, range 0.32 to 0.78.
The median email subscriber generates $4.40 in email-attributed revenue per year — a few high-AOV brands pull the portfolio aggregate to $12.78. Range: under $1 to nearly $150. Benchmarks from 834,474 subscribers across 15 DTC brands.
Most post-purchase flows are built on assumptions. Build yours based on what customers actually buy, in what order, at what frequency.
Klaviyo is great, but there are metrics it doesn't give you out of the box—metrics that actually change how you run your email program. Here are five we built ourselves.

Klaviyo costs our clients $150-$3,500/month. Here's what drives the price, where the hidden costs are (dead profiles, SMS credits, auto-upgrades), and why it's still worth it at 30-50x ROI.
66% of e-commerce subscribers already bought before the welcome flow sent. The real conversion window is 7 days. Benchmarks from 159K customers across multiple DTC brands.
Browse abandonment is consistently a top-5 revenue flow — lower conversion per email, but massive volume. Real browse abandonment emails from four ecommerce brands, plus how to build the flow and avoid the OR vs. AND filter mistake.
Per-brand data on send volume vs campaign revenue: more sends bring more revenue for 11 of 15 brands, but per-send efficiency softens as you scale. Median $0.076 per send, range $0.02–$0.73.
Engagement tells you who's opening emails. It doesn't tell you who's buying. Those are different things—and the difference is costing you money.
There is no universal best day to sell: across 13 DTC brands the busiest and highest-AOV days are brand-specific. The one loose pattern is a modest weekend AOV dip — and even that ranges from 2% to 66% by brand.
At the median DTC brand, 77% of customers buy once but repeat buyers drive ~49% of revenue. The 5+ buyer is worth ~9.8x a one-timer — and the conversion funnel accelerates after the second purchase.
