Email & SMS Revenue Share by Vertical (2026)

Pull your last twelve months of Shopify revenue, then pull the email and SMS attributed revenue from your sending platform, and divide one by the other. That single percentage tells you more about how fragile your unit economics are in 2026 than almost any other number on the dashboard, because it shows how much of your sales you actually own versus rent from an ad auction. Most operators have never run the math, and the ones who do are usually surprised. Here is what the healthy range looks like, why it matters as paid acquisition keeps getting more expensive, and what to expect when you start auditing your own.

What "owned revenue share" actually measures

Owned-channel revenue share is email plus SMS attributed revenue divided by total store revenue over the same window. Email here means your broadcast campaigns plus your automated flows. SMS means the same split for text. "Owned" is the operative word: these are audiences you can message for free, on your schedule, without bidding against a competitor for the privilege. That is the opposite of paid social and paid search, where you re-rent the audience every single time.

Two definitions trip people up. The first is attribution. Your sending platform typically counts a sale as email-driven if the customer clicked an email within a 5-day window, and SMS-driven within a 1-day window. Those windows are generous, and they overlap with paid, so the number is directional, not surgical. The rule we give operators is simple: compare your share to itself over time before you compare it to anyone else's, because your window is your window.

The second is what counts as "total revenue." Use the same store-wide number your finance team closes the month on, not a channel-filtered slice. When we talk to founders who think their email is doing 45% of revenue, half the time they divided email revenue by online revenue and forgot wholesale, or they double-counted flows and campaigns. Clean the denominator first.

The healthy band: 20 to 40 percent of revenue

Across the benchmark reports, the same range keeps showing up. Mature ecommerce brands generate roughly 25-40% of total revenue from email and SMS combined, and well-optimized Shopify stores cluster around a 28% median for email alone. Practitioner guidance lands in the same place: a brand "operating on all cylinders," with a real mix of organic, direct, paid and referral traffic, usually sees owned channels at 20-30% of revenue.

So the working band is 20-40% of total revenue from email plus SMS, with a healthy center near 28%. Below 15% is the warning zone. It almost never means the channel is tapped out. It means flows are missing, the list is under-grown, or campaigns are the only thing running. Above 45-50% can also be a flag, but a different one: it often means acquisition has stalled and owned channels are propping up a shrinking top line, or the brand is discounting its own list to hit the number.

The goal is not the highest possible owned-channel share. It is a high share sitting on top of a growing business. A brand doing 35% owned on a top line that is up 40% year over year is winning. A brand doing 35% owned because new-customer revenue collapsed is just measuring its own decline.

When I talk to founders auditing this for the first time, the reframe that lands is that owned revenue share is a margin number disguised as a marketing number. The revenue you pull through a flow has no media cost attached. As blended CAC keeps climbing, the brands that survive are the ones who quietly moved more of their revenue into channels that do not reprice every quarter.

Email and SMS revenue share by vertical

Vertical sets your baseline before you do anything well or badly, and it comes down to purchase frequency and order value. Categories people buy often and consume (food, beverage, supplements, beauty) get more chances to trigger replenishment and post-purchase flows, so owned channels carry more of the mix. High-ticket, low-frequency categories (electronics, big-ticket sporting goods) lean on search, marketplaces and considered research, so owned share runs lower even with a great program.

The honest caveat: none of the major platforms publish a clean "owned revenue share by vertical" table. The figures above are healthy-band midpoints we triangulated from revenue-per-recipient by vertical, the categories Postscript flags as top SMS earners (Health & Wellness and high-AOV Home & Lifestyle), and store-maturity data. Treat them as the center of a wide range, not a target line. A subscription supplement brand can run 40%; a one-and-done electronics brand can be perfectly healthy at 14%.

If your number sits well below the bottom of your vertical's range, the problem is almost never the vertical. It is the program. That is the better news, because the program is the part you control. The same dynamic shows up in our beauty brand unit economics work: the brands with durable margins are usually the ones whose retention engine is doing real work.

Why the number scales: list size, repeat purchase, and flows

Total owned revenue is roughly list size times messages per contact times revenue per message. So yes, a bigger list helps. But the variable that actually moves the share is program maturity, because that is what turns a list into revenue.

Read that chart as a build order, not a destiny. A beginner program (occasional campaigns, no flows) lands at 5-12% of revenue. Turn on basic flows and a weekly campaign cadence and you are at 18-25%. Build out eight or more flows with real segmentation and you reach 28-35%. A full flow suite with predictive segments tops out around 35-45%. The list barely changed between those stages. The machinery around it did.

Repeat purchase rate is the multiplier underneath all of this. Every repeat order is a fresh trigger: a post-purchase cross-sell, a replenishment reminder, a winback. Those are the highest revenue-per-recipient messages you can send. The pattern we see again and again is that brands obsess over list growth while their flow coverage has holes you could drive a truck through. When we've helped operators fix this, the move that worked was not buying more traffic, it was closing the gaps in the flow suite so the existing list finally got worked properly. One brand we sat with had a welcome flow and nothing else; adding cart, browse and post-purchase flows roughly doubled owned share inside a quarter without spending a dollar more on acquisition.

Email vs SMS, flows vs campaigns: where the revenue lives

Operators tend to overthink the email-versus-SMS question. Per recipient, the two channels are close. The split that actually matters is flows versus campaigns, and it is not close at all.

The takeaway is blunt: campaign sends earn about a dime each, flow sends earn multiples of that, and the gap holds across both email and SMS. Automated email drives roughly 37% of email orders from about 2% of sends. The same automation premium holds on the SMS side, where automated texts earn several times what a campaign blast does per send. A reasonable target for a mature program is flows carrying 40-50% of email revenue and 30-40% of SMS revenue. If your flows are under 30% of owned revenue, that is your single highest-return project, and it costs nothing but build time.

This is also why the channel-mix question is downstream of the retention question. We dug into the paid side of this in our marketing channel mix benchmarks breakdown, and the conclusion rhymes: the cheapest revenue you have is the revenue you already earned the right to message.

How to audit your own owned-channel share this week

You do not need a project plan. You need an afternoon. Pull total store revenue and email plus SMS attributed revenue for the trailing 90 days and divide. Then compare to three things, in order: your vertical's range from the table above, your own number from a year ago, and the flow-versus-campaign split inside your owned revenue.

If your total share is low, look at flow coverage before anything else. Do you have welcome, abandoned cart, browse abandonment, and post-purchase flows live on both email and SMS? Most brands under the benchmark are missing at least two of those. If your share is healthy but flat year over year, the question shifts to list growth quality and segmentation. And if your share is suspiciously high (north of 45%), check whether new-customer revenue is actually growing or whether owned channels are just a larger slice of a smaller pie. Why this matters for your business: a brand with a thin owned-channel share has its margin tied to ad costs it does not control, and that is the kind of fragility that does not show up until the quarter it really hurts.

If owned-channel revenue is becoming a real margin lever rather than a vanity line, a fractional CFO can help you set targets against contribution margin and the discount math behind every flow.
