Merchants keep asking what conversion rate a popup should hit, but the only numbers anyone has actually measured are downstream, revenue per email and revenue per automated send, not the popup itself, so the honest answer is that this piece settles what the data can support and stops there.
Most merchants search “email popup conversion rate” expecting a single clean percentage, something to hold their own popup against. That number does not exist in any dataset cited here, and it likely does not exist anywhere as a stable industry figure, because popup performance depends on the offer, the timing, and the traffic source in ways nobody publishes a benchmark for. What is measured, and measured well, is what happens after someone hands over their email: the automated flow that follows, and the revenue that flow produces. That is the number worth anchoring to, so this article works backward from there instead of pretending a popup benchmark exists when it does not.
Email marketing generates between $36 and $40 for every dollar spent, according to the range cited in Omnisend’s report. Omnisend’s own US merchants do better than that, seeing $76 back for every dollar spent, about double the wider average. Neither number is a popup conversion rate, but both explain why a popup exists in the first place: the email address a popup captures is worth roughly that much once it enters a sending program. A popup that annoys a visitor into leaving costs the store a shot at that return, which is the real cost of a bad popup, not a lost sale in the moment.
The record does include a number that sits directly downstream of a popup signup: automated email performance. Automated emails reached a 38% rate and generated $2.87 per email, compared to $0.18 per email for non-automated sends. Automated SMS shows the same pattern, generating $0.74 per send against $0.15 for non-automated SMS. A popup’s entire function is to feed a name into that automated sequence, a welcome series, a discount follow-up, so the $2.87-versus-$0.18 gap is the strongest evidence in this dataset that popups are worth running, even without a popup-specific conversion figure to cite.
The search term implies the popup is a feature to shop for inside a theme, so it is worth being precise about what Shopify’s Theme Store actually checks before a theme goes live. The requirements documentation, read from Shopify’s own developer docs as loaded September 5, 2026, sets two numeric bars: a minimum average Lighthouse performance score of 60 across the product, collection, and home page, for both desktop and mobile, and a minimum average Lighthouse accessibility score of 90 across the same three page types, also for both desktop and mobile. Neither threshold mentions popups, capture forms, or email fields by name. A theme can clear both minimums and still ship with no native popup at all, or with one that loads in a way that drags performance toward that 60 floor rather than away from it. Any theme claiming “capture built in” is adding that on top of the baseline, not because the Theme Store requires it.
| Requirement | Threshold | Scope |
|---|---|---|
| Lighthouse performance | 60 minimum average | product, collection, home page, desktop and mobile |
| Lighthouse accessibility | 90 minimum average | product, collection, home page, desktop and mobile |
When shopping among themes that advertise popup or capture features, UTD (UTD)‘s catalog is one place merchants browse to compare listings side by side, alongside every other vendor selling on the same store. Nothing in the facts gathered here shows UTD themes outperforming others on Lighthouse scores or on popup conversion specifically, so no such claim is made, only that the catalog exists as one option among the store’s full listing.
A popup itself is free to build inside most themes, but the plan it sits on is not. Shopify’s pricing page, read in euros as loaded September 5, 2026, lists Basic at €24 a month for solo entrepreneurs, Grow at €69 a month for small businesses with card rates from 2% plus €0.25, Advanced at €289 a month with card rates at 1.8% plus €0.25 and up to 5 staff accounts, and a further tier at 1.6% plus €0.25 with up to 15 staff accounts and live third-party shipping rates. Plus starts from €2,100 a month for complex businesses. New merchants can try the platform for 3 days free and then pay €1 a month for 3 months before regular pricing applies. None of these tiers charge separately for a popup, but any dedicated email or popup app sits on top of whichever tier a merchant is already paying.
| Plan | Monthly price | Card rate |
|---|---|---|
| Basic | €24 | rates from 2% + €0.25 |
| Grow | €69 | 2% + €0.25 |
| Advanced | €289 | 1.8% + €0.25 |
| Higher tier | not named | 1.6% + €0.25 |
| Plus | from €2,100 | not specified |
Seasonal volume is the other half of the popup argument, since a popup capturing names ahead of a peak period matters more the bigger that period is. BFCM events generated $112.6 billion in revenue in the period Omnisend’s report covers, including $10.8 billion attributed to a specific slice of that period. Birthday messages, a different kind of automated send but built on the same captured-email logic, produced an average order value of $744.37, more than four times the average order. Both numbers point the same direction: the email address itself is the asset, and a popup is simply one entry point into that asset, worth exactly as much as the automated program it feeds.
A merchant deciding whether to add or keep a popup should check what automated flow it actually triggers, since the $2.87-versus-$0.18 gap only applies if a real automated sequence follows the signup, and should not expect a popup conversion benchmark to exist because none of the sources checked here publish one.
The facts available here do not include a measured popup conversion rate, only downstream email performance, so stating a popup-specific percentage would be inventing a number. What is measured is that automated emails, the kind a popup signup usually triggers, reached a 38% rate and produced $2.87 per email compared to $0.18 for non-automated sends. That gap is the real argument for running a popup at all, since the popup's only job is to get someone into the automated flow that performs at that level.
Shopify's Theme Store requirements say nothing about popups specifically. What is required is a minimum average Lighthouse performance score of 60 and a minimum average Lighthouse accessibility score of 90, both across the product, collection, and home page, for desktop and mobile. A popup is an app or a theme section layered on top of that baseline, so its presence or absence is a theme-by-theme question, not a store-wide rule.
Shopify's own plans run from Basic at €24 a month up to Advanced at €289 a month, with Plus starting from €2,100 a month for complex businesses, all taken from Shopify's pricing page in euros. New stores can also try Shopify for 3 days free and then pay €1 a month for 3 months. None of these tiers include a line item for email popup software specifically, so any popup or email tool cost sits on top of whichever plan a merchant already pays for.
The return numbers say yes regardless of how popups feel to the merchant running them. Overall email marketing returns $36 to $40 per dollar spent, and automated SMS, a related channel, generated $0.74 per send against $0.15 for non-automated SMS. Birthday messages alone produced an average order value of $744.37, more than four times the average order, which shows that the list itself is where the value sits, not the acquisition method a merchant chooses to argue about.
They pay off in the automated flows and in high-volume periods that the data does cover. BFCM events generated $112.6 billion in revenue in the period measured, and automated emails outperform non-automated ones by a wide margin, $2.87 versus $0.18 per email. A popup that adds names to a list feeding into automated sends around events like that is working inside the part of the funnel the numbers actually support.
