How to Find Shopify Plus Brands That Need Your Agency (2026)
Plus tells you a merchant bought a bigger contract. It does not tell you they need you. Here is how to list Plus brands, add the layers that predict fit, and reach the right person with a reason that is dated.
To find Shopify Plus brands that need your agency, treat Plus as a size-and-contract filter rather than a buying signal: list Plus stores from an ecommerce store database or a technology lookup, cut the list down with category, region, installed apps and store quality, then wait for a dated event that connects to the problem you solve before anyone sends an email. The lookup takes an afternoon. Choosing a signal that predicts need decides whether the list is worth anything.
Snipe Outbound is a managed outbound provider for agencies and software companies that sell to ecommerce brands, so we have an obvious interest in the "hire it out" answer below. This guide describes what Shopify and the lookup tools say on their own pages, links each page, and dates the check. Anything we could not verify on a vendor's own page today is not here.
What does Shopify Plus actually tell you?
Shopify's own Shopify Plus plan documentation describes Plus as the tier with unlimited staff accounts, support for 9 expansion stores, a wider B2B feature set (unlimited catalogs, catalog assignment to companies and locations, deposit requirements and partial payments), checkout customization through the Checkout Branding API and checkout extensions, additional API calls with the option to request higher rate limits through support, and priority 24/7 phone and chat support. The same page offers Plus on a 1-year or a 3-year term. Checked November 3, 2026.
Read that list as a prospector. Every item is a capability the merchant bought, plus a contract length. None of it says the merchant has a conversion problem, a tired retention program or a budget line for your service this quarter. Plus is useful in three narrow ways:
- Scale proxy. Plus is where merchants land when volume, staff count or international structure outgrows the lower plans.
- Budget plausibility. A brand on a multi-year platform term is used to paying for software. Plausible is not funded.
- Complexity proxy. Expansion stores, B2B catalogs and customized checkout mean more moving parts, and moving parts are where agencies are relevant.
The limits deserve the same airtime. A contract tier is not a problem, the plan does not name who owns the decision, and nothing about a plan is dated. Plus is a fit attribute, and fit is not timing.
Where can you look up Shopify Plus brands?
Three routes are worth your time. Each has a catch.
1. An ecommerce store database with a plan filter
Store Leads documents a Plan attribute and states its limit directly: "For Shopify, we are only able to identify Shopify Plus stores." The filter is a flag, not a ladder. Its instructions for listing Plus stores are to open the Domains page, filter on Plan so only Shopify Plus stores are included, filter on Status so only Active stores are returned, and run the search. Its product page says data is updated weekly. Checked November 3, 2026.
Its tips page is more useful than the filter. Store Leads notes that a Plus contract comes with 10 Shopify Plus accounts, so subsidiary and test stores sit next to real businesses, and it recommends the Platform Rank Percentile filter because "primary Shopify Plus accounts rank in the top 3% of the entire Shopify Database." It also describes combining Plan set to "Plus" with a "Last Plan Change At" filter to surface recent upgrades, which is the one genuinely dated signal in the category.
2. A technology lookup
BuiltWith's Shopify Plus page describes Plus as "an ecommerce platform for high-volume and enterprise merchants" and reports 117,090 live sites globally with 59,386 in the United States. It also publishes a separate technology called Shopify Plus Inferred, at 55,437 live sites globally, with this note: "Shopify Plus is undetectable using public web detection methods since 2024. This technology represents websites that could be using Shopify Plus based on their age, usage and non-usage of other premium and non-premium technologies." Checked November 3, 2026.
That note should change how you use any Plus list. Part of what the market calls Plus detection is inference, so treat a Plus flag as a probability, confirm size another way, and keep the word "Plus" out of your email unless you are certain.
3. Shopify's own published stories
Shopify keeps a merchant case-study library under the headline "Find out why the world's best brands choose Shopify," filterable by previous platform, industry, market and the Shopify products used, with 622 stories listed on November 3, 2026. It is small next to a database and self-selected toward merchants happy to be written about. It is also the cleanest free source of named, confirmed, larger merchants, and its "previous platform" filter is a replatform history no plan filter gives you.
Do not guess from the storefront. If you cannot verify the plan, target on what you can. Our guide to finding Shopify stores by app or tech stack covers the mechanics.
How do you layer fit on top of the Plus signal?
Plus on its own is a bad list. Add three layers in order.
- Attributes you can verify. Category, region and language, installed apps and the absence of a competing app, product count, and store quality such as the rank percentile Store Leads suggests.
- The role that owns your outcome. Head of ecommerce, retention lead, performance marketing lead, engineering lead. The plan tells you nothing here.
- A dated event. One observable, recent, sourced thing that explains why you are writing now and not last quarter.
Revenue proxies belong in layer one, with a caution. Store Leads publishes monthly sales and visits as estimates, not reported figures, so use them to rank a list, not to assert anything.
Which trigger fits which agency type?
This table pairs each service with the fit layer that narrows a Plus list and the dated event that makes a first email specific.
| Who you are | Fit layer on top of Plus | Dated trigger worth waiting for |
|---|---|---|
| CRO and experimentation | Considered-purchase category, enough traffic to test, no incumbent testing tool installed | A new ecommerce or growth lead starts; a redesign or theme change ships |
| Paid ads and media buying | Active ad presence, multiple markets, a range that supports prospecting spend | A performance marketing hire is posted; a new market or expansion store appears |
| Klaviyo and retention | Subscription or repeat-purchase category; an email or SMS app newly installed or removed | A retention or lifecycle role is posted; a messaging app change shows in the stack |
| Shopify development | B2B catalogs, expansion stores, customized checkout, an aging theme | A replatform onto Shopify, or a plan change into Plus in the last few weeks |
| Shopify apps and ecommerce SaaS | The workflow your product serves is visibly present and a competing app is absent | A competing app is uninstalled; a launch, funding round or operations hire lands |
Record each trigger's source and date, and connect it in writing to the problem you solve. An event explains timing. It does not prove need, budget or authority, and you verify all three in conversation. Our guides for CRO agencies, paid ads agencies, Klaviyo agencies and Shopify development agencies go deeper.
How do you turn the list into outreach?
A verified Plus list is an account list. It is not yet a contact list, an offer or a campaign.
- Verify the person, not just the company. Store Leads says its own contact data is non-personal, so named contacts come from a separate enrichment source. Check that the person still holds the role and that the mailbox accepts mail, and do not write to a general store inbox as if it were a decision maker.
- Lead with a sample rather than an offer to audit. A CRO team sends one named friction point with its evidence; a paid ads team one observation about current creative or account structure; a retention agency one missing flow and what it would say; a development agency one measured page-speed or checkout finding; an app a short recording of the workflow in that merchant's category. Give something away instead of asking for a call to find out whether a problem exists.
- Keep deliverability boring. Dedicated sending domains in your own brand, a warm-up period before real volume, low daily volumes per mailbox, one obvious unsubscribe path, and immediate suppression of anyone who asks. These practices help contain deliverability risk. They do not eliminate it, and no sending setup makes a weak offer land. The cold email guide for ecommerce agencies covers the offer patterns.
- Measure with honest denominators. Brands contacted, interested replies, sales calls booked, calls held and clients won, split by the signal that put each account on the list.
Should you build this or hire it out?
Build it yourself when someone can own the weekly work: refresh the list, check the triggers, write the samples, send, and answer replies within a day. The data subscription is the small part of that cost. The time is the large part, and it recurs.
Hire it out when finding Plus brands is not your bottleneck. If you know which brands you want and the gap is writing, sending and following up, a better list will not close it. We laid out that choice in full in StoreLeads vs a managed outbound agency.
Snipe runs the targeting, the sending infrastructure, the copy and the reply desk, and prepares qualified sales calls. Your reps own discovery, the proposal and the close. The Market Map and the sending domains are built in your name and stay with you. Pricing is quoted after a call, once scope is agreed. See outbound for ecommerce SaaS and agencies.
Frequently asked questions
How can I tell whether a store is on Shopify Plus?
Use a data source that tracks the plan rather than inspecting the storefront. Store Leads documents a Plan attribute and says that for Shopify it can only identify Plus stores. BuiltWith notes that Plus has been "undetectable using public web detection methods since 2024," which is why it publishes a separate Shopify Plus Inferred technology. Both checked November 3, 2026. Treat any Plus flag as a probability.
Is Shopify Plus a good filter for agency prospecting?
It is a reasonable size and complexity filter and a poor need filter. Shopify's plan page describes Plus in terms of staff accounts, expansion stores, B2B catalogs, checkout customization, API headroom and support, on a 1-year or 3-year term. That is what the merchant bought, not a problem they want solved. Use Plus to narrow, then add category, role and a dated event.
How many Shopify Plus brands are there?
We do not publish our own count. BuiltWith's Shopify Plus page reported 117,090 live sites globally and 59,386 in the United States on November 3, 2026, plus a separate Shopify Plus Inferred figure of 55,437 live sites. Those are one vendor's detection counts on one date, and they move.
Can I filter Shopify stores by plan in Store Leads?
Yes, for Plus only. Its help pages describe filtering Plan to Plus with Status set to Active, combining Plan with "Last Plan Change At" to find recent upgrades, and using Platform Rank Percentile to separate primary stores from the subsidiary and test stores that come with a Plus contract. Checked November 3, 2026.
What should the first message say?
Name the thing you observed on their store or in their stack, say what you would change and why, and keep the first step small. Specific beats personalized.
Where should you start?
Bring the kind of ecommerce brand you win most often and what a new client is worth to you. On a call, Leon walks through a Market Map of fitting brands, the signals we would filter on, the first offer we would test, and whether running it in-house is the better call at your stage.
