Square Orders to Email Attribution, broken down by row.

At a glance

A cross-platform revenue-at-risk audit. It takes Square Orders revenue and cross-references each order’s customer against your email platform (Klaviyo, Dotdigital, Mailchimp, or similar) to estimate how much of that revenue your email programme is influencing, and crucially how much is going unattributed despite an active, paying email audience. A large unattributed share while you run regular campaigns points to broken matching, missing capture, or an underperforming programme.

What it counts	Square Orders revenue in the window, split by whether the order’s customer is matched to an engaged contact in your email platform (attributed) or not (unattributed). Reported per row (per channel or per segment).
Channel / source treatment	Cross-platform by definition. It joins Square Orders (revenue, customer email_address) to your email platform’s contact and engagement data. Meaningless without an email connector configured.
How orders are matched	On the customer email_address attached to the order, against subscribed, engaged contacts in the email platform. Guest orders and POS orders with no email captured cannot be attributed.
Currency / unit	Currency (the order total, total_money.amount, in the location’s currency). The headline is the attributed vs unattributed split of Square revenue.
Time window	30D (attribution assessed over the trailing 30 days).
Alert trigger	Fires when more than 30% of Square revenue is unattributed despite an active email programme. The split is shown per row so you can see where the gap sits.
Roles	owner, marketing, finance
Why it is revenue at risk	If most revenue is unattributed while you mail regularly, either your email programme is not actually driving sales (an efficiency problem) or your matching and capture are broken (a measurement problem). Both hide real money: wasted spend or unreached buyers.
What it is not	Last-click marketing attribution in the ad-platform sense. It is a coarse, owned-data estimate of email influence on Square revenue, designed to surface a broken or under-leveraged email channel, not to settle multi-touch credit.

Calculation

Calculated automatically by cross-referencing your Square Online orders against your connected email platform. See the At a glance summary above for what the metric tracks and the worked example below for a typical reading.

Worked example

A US home fragrance brand on Square. One store plus a Square Online storefront, running weekly campaigns in Dotdigital. The 30-day window covers 14 Feb 26 to 15 Mar 26. Each row is a channel or segment.

Row (channel / segment)	Square revenue	Attributed to email	Unattributed	Unattributed %
Square Online (web)	$84,000	$46,000	$38,000	45%
Square POS (in-store)	$120,000	$9,000	$111,000	93%
Square Invoices (B2B)	$26,000	$1,000	$25,000	96%
All channels (this card)	$230,000	$56,000	$174,000	76%

Three things to notice:

1. POS revenue is almost entirely unattributed, and that is mostly a capture problem, not an efficiency one. In-store buyers who never gave an email cannot be matched, so 93% of POS revenue shows as unattributed. That is not your email programme failing; it is a capture gap at the register. Read it alongside Customer Capture Source (POS vs Online) before drawing conclusions.
2. Read the web row in isolation for the true programme read. On Square Online, where email is captured at checkout, 45% is still unattributed. That is the number that actually tests your email programme. If you mail weekly and still less than half of web revenue is email-influenced, the levers are matching quality, segmentation, and campaign relevance.
3. The blended 76% crosses the alert, but the alert is about active programmes. With weekly Dotdigital sends and 76% unattributed overall, the Nerve Centre alert fires. The instinct to panic at 76% is wrong though, strip out POS capture gaps first. Pair with High-Value Square Customers Unengaged on Email to see which spenders are slipping through.

Sibling cards merchants should reference together

Card	Why pair it with Square Orders to Email Attribution
High-Value Square Customers Unengaged on Email	The customer-level view of the same gap. Unattributed revenue and unengaged high spenders are two reads on one problem.
Customer Capture Source (POS vs Online)	Explains how much of the unattributed revenue is simply POS orders with no email captured, separating capture gaps from programme weakness.
Email Opted-In Customers (Directory)	The reachable audience that should be driving attributed revenue. Low opt-in caps how much email can ever attribute.
Total Revenue (30d, all channels)	The denominator. This card splits that headline revenue by email influence.
Revenue by Channel (POS / Online / Invoices)	Attribution differs sharply by channel. The channel split clarifies why the blended number looks the way it does.
dotdigital	The email-platform side of the join. Use it to confirm campaign sends, opens, clicks, and platform-reported revenue per campaign.

Reconciling against Square

Where to look in the Square Dashboard:

Square Dashboard, Reports, Sales summary. Set the same window and confirm total Square revenue, that is the denominator this card splits. Square also exposes a Marketing area with its own campaign reporting, but Square’s native marketing reporting only covers Square Marketing campaigns, not your external email platform, so it cannot reproduce this cross-platform split.

Other Square Dashboard views that look like the same number but aren’t:

• Reports, Sales summary, Gross sales: confirms the total Square revenue this card divides. It does not split by email influence.
• Marketing, campaign reporting (Square Marketing): attributes revenue to Square’s own email tool only. If you use an external platform, this view misses it entirely.
• Customers, Insights: behavioural summaries, not revenue attribution.
• Reports, Payments: payment events, not orders, and no email dimension.

Why our number may legitimately differ from Square Dashboard:

Reason	Direction of divergence
Email match on email_address. Orders with a typo’d, secondary, or missing email cannot be matched, so they fall into unattributed even if the customer is engaged elsewhere.	Vortex IQ may over-report unattributed until emails are cleaned
Guest and POS orders. Orders with no customer email captured are structurally unattributable. Square Dashboard total revenue includes them; this card puts them in unattributed.	Unattributed share rises with POS and guest mix
Attribution window. A purchase shortly after an email engagement counts as influenced; a purchase long after does not. Window choice shifts the split.	Split moves with the chosen window
Sync lag. Recent orders or email engagement may take a cycle to reach our index.	Self-resolves within minutes

Cross-connector reconciliation:

Card	Expected relationship	What causes legitimate divergence
dotdigital	The email platform’s own attributed revenue should be in the same ballpark as the attributed figure here	The two use different attribution models (platform last-click vs owned-data email match), so they will not match exactly. A large divergence points to matching or capture problems, not a bug.
klaviyo	Same as above for Klaviyo-based merchants	Klaviyo attributes on click and order events within its own window. Treat it as a directional cross-check, not a reconciliation, since Square is the merchant of record for the revenue.

The Square owned-data advantage and its catch: because Square is one merchant of record across POS, web, and invoicing, this card can split your entire revenue base by email influence, not just the web slice an ad platform would see. The catch is that attribution is only as good as the email captured on each order, and POS orders frequently have none. So the honest read is per channel: judge your email programme on the web row, and treat the POS row as a capture opportunity rather than a programme verdict.

Known limitations / merchant FAQs

Is this real marketing attribution? No, and it does not pretend to be. It is a coarse, owned-data estimate of how much Square revenue your email programme is influencing, built by matching order customers to engaged email contacts. It is designed to surface a broken or under-leveraged email channel, not to settle last-click or multi-touch credit the way an ad platform would.

Why is so much revenue unattributed? Usually because of orders with no matchable email, most often POS orders where the customer never gave an address. Square Orders revenue includes every channel, and in-store buyers frequently check out anonymously. Always strip out the POS capture gap (read the web row alone) before concluding your email programme is underperforming.

Should I judge my email programme on the blended number? No. Judge it on the Square Online (web) row, where email is captured at checkout and orders are matchable. The blended figure mixes in POS and guest orders that can never be attributed, which makes any email programme look worse than it is. The web row is the fair test.

My email platform reports more attributed revenue than this card. Who is right? Neither is wrong, they use different models. Your email platform attributes on its own click-and-order events within its own window; this card matches order customers to engaged contacts in owned data. Expect them to be in the same ballpark, not identical. A large gap points to matching or capture issues worth investigating, not a defect.

How do I improve the attributed share? Three levers in order: capture more emails (especially at the register), tighten matching by deduplicating customer emails, and make the email programme genuinely drive purchases through better segmentation and relevance. The first two are measurement fixes; the third is the actual marketing work.

Does this count Square Invoices and POS revenue? Yes, the denominator is all Square Orders revenue across web, POS, and Invoices. That is deliberate, it shows the true share of your whole business that email touches. But because POS and invoice orders are often emailless, expect their unattributed share to be high, and read them as capture context rather than programme performance.

Can I change the threshold or window? Yes. The default alert fires above 30% unattributed revenue over a 30-day window while an active email programme is running. Both the threshold and the attribution window can be tuned per merchant in your Vortex IQ workspace settings to fit your send cadence and channel mix.
