Popupsmart vs Sleeknote
Sleeknote, from Aarhus in Denmark, sells popups, slide-ins, bars and embedded forms to ecommerce teams, with every feature on every plan, gamification as an add-on and no free plan. Popupsmart is a popup builder that starts free and puts every targeting rule and gamified popup on every plan. They count traffic differently, Sleeknote by visitors and Popupsmart by pageviews, so this page prices both at the same traffic with the conversion Sleeknote prints beside its own prices. Each figure comes from the two companies' own pages, Popupsmart's 2026 benchmark or the products' reviewers, with the date it was read.

Choose Popupsmart if…

- You want spin-to-win and other gamified popups without paying for an add-on
- You want AI to draft the whole popup from a prompt, and Smart Mode to pick who sees it
Choose Sleeknote if…
- You want A/B testing, analytics and every other feature from the entry plan up
- You run many websites and want them all on the entry plan
- You want scratch cards, quizzes and seasonal calendars as well as spin-to-win
Popupsmart or Sleeknote: which should you choose?
Choose Sleeknote if you want every feature from the first plan, A/B testing and analytics included, unlimited websites, phone support, and the widest choice of games: scratch cards, quizzes, Learn to Earn and seasonal calendars. Choose Popupsmart if you want to start free, pay less at most traffic levels, get spin-to-win without an add-on, or have AI draft the popup. On price, at the 3 pageviews per visitor Sleeknote prints beside its plans, Popupsmart costs less at four of the seven traffic levels on this page, the same at one and more at two.
Sleeknote doesn't divide features by plan. Its entry plan, $69 a month for up to 25,000 visitors, about 75,000 pageviews by its own figure, or $55 on annual billing, has everything the larger plans have: A/B testing, analytics with goal tracking and revenue attribution, exit intent, geo-targeting, SiteData rules built on your own site's data, product recommendations, coupon codes, multistep forms, embedded forms, and unlimited campaigns on unlimited domains. Every plan comes with phone, chat and email support. Its Gamification add-on, $95 a month instead of $69 at the entry tier, adds Spin to Win, Scratch to Win, Learn to Earn, a Seasonal Calendar and quizzes. The money-back guarantee runs 30 days on monthly plans and 100 days on annual ones. Its integrations page lists 277 tools and marks 27 as direct integrations, among them Klaviyo, HubSpot, Salesforce and European email tools such as Voyado, Rule.io and CleverReach. Its Capterra reviewers praise its ease of use most, and its Trustpilot reviewers its support.
Popupsmart's case is the start and the price. Its free plan carries 5,000 pageviews a month with every targeting rule and campaign type; Sleeknote has a 14-day trial. Basic costs $39 a month for 50,000 pageviews on three websites, against Sleeknote's $69 for about 75,000, and at 500,000 pageviews Popupsmart's Expert costs $159 to Sleeknote's $240; Sleeknote costs less at 150,000 and 375,000. Spin-to-win, lottery ball and surprise box popups are on every Popupsmart plan, the free one included, where Sleeknote sells its games as an add-on. The AI builder drafts a whole popup from a prompt and Smart Mode, on paid plans, picks who sees it; Sleeknote's AI rewrites and translates the text you write. On Shopify, Popupsmart creates a unique discount code for each visitor; Sleeknote shows codes from a list you upload. And Popupsmart can send each new subscriber an autoresponder email on every plan; Sleeknote doesn't email subscribers itself.
A word on who wrote this. I founded Popupsmart in 2018, after five years of growth consulting at Flatart, the agency I started in 2013, so I'm not a neutral judge here, and I've made the page checkable instead. Every Sleeknote fact is from sleeknote.com, its help center or its Shopify App Store listing, read on 27 Sep 2026. Sleeknote has few public reviews anywhere: 6 on G2, 13 on Capterra, 16 on Trustpilot and 4 on the Shopify App Store. So we read every one of them, the Danish ones in Danish, and give each site's figures under its own name. They are too few to show how often Sleeknote goes wrong for its users, and this page doesn't pretend otherwise.
How the two differ
Popupsmart
Popupsmart is a popup builder billed by pageviews that starts free: every targeting rule and gamified popup is on every plan, and the plans differ by traffic, websites, analytics and A/B testing.
The free plan carries 5,000 pageviews a month on one website with every targeting rule and campaign type, spin-to-win included, one popup live at a time and Popupsmart branding. Paid plans run from $39 a month for 50,000 pageviews on three websites to $159 for 500,000 on unlimited websites, about a sixth less on annual billing. They add unlimited popups, analytics, custom CSS and fonts, and Smart Mode, which picks the audience with AI; A/B testing starts on the Advanced plan. The AI builder drafts a whole campaign from a prompt. Popups appear through one script, added by hand, through Google Tag Manager, the Shopify app or an optional WordPress plugin. On Shopify it targets by cart value, contents and purchase history, creates a unique discount code for each visitor and reports the revenue its popups drive. Each lead goes to the tool you connect, with an autoresponder email on every plan.
Sleeknote
Sleeknote is an on-site engagement tool for ecommerce billed by monthly visitors: every plan has every feature, unlimited campaigns and unlimited domains, gamification is a paid add-on, and there is no free plan.
Plans run from $69 a month for up to 25,000 visitors to $470 for 500,000, with a custom quote above; paying yearly takes 20% off. A visitor is what Google Analytics calls a user, counted once however many pages they view, and the pricing page puts 25,000 visitors at about 75,000 pageviews. Every plan has popups, slide-ins, sidebars, bars and embedded forms; A/B testing and analytics with goal tracking and revenue attribution; targeting by behavior, page, referral, UTM parameter, location, cookie and IP address, and by your own site's data through SiteData; product recommendations; and phone, chat and email support. The Gamification add-on, $95 a month at the entry tier, adds Spin to Win, Scratch to Win, Learn to Earn, a Seasonal Calendar and quizzes. A 14-day trial needs no card. One script covers any website, and a Shopify app runs it inside Shopify admin. It sends no email itself: leads go to your email tool, or to your Shopify customers, and stay in Sleeknote for three months.

Monthly list prices, billed monthly, as each company's pricing page showed them from a US location on 27 Sep 2026. Popupsmart counts pageviews; Sleeknote counts monthly visitors, what Google Analytics calls users, each counted once however many pages they view. To put both on one scale, the bars use 3 pageviews per visitor, the figure Sleeknote prints beside every plan on its pricing page (up to 25,000 visitors, "around 0 – 75,000 pageviews"), and price each tier at the smallest plan of each product that covers it, without Sleeknote's Gamification add-on. The tiers are every plan limit of both products up to 500,000 pageviews. If your visitors view more than 3 pages each, Sleeknote's plans stretch further; divide your own monthly pageviews by your monthly users to see which figure fits your site.

Gamification and targeting, against 28,674 campaigns
Sleeknote puts every feature on every plan but sells gamification as an add-on, and has no free plan; Popupsmart puts gamified popups and every targeting rule on every plan, the free one included. Sleeknote's home page says its wheels, scratch cards and quizzes "convert up to 132% better than a plain form". We measured these features in our own 2026 benchmark: 28,674 campaigns from 11,533 businesses that ran a popup with Popupsmart between January 2024 and September 2026. The two companies measure differently, so neither figure settles the other. And not every result helps our case: the gamified popups we include on every plan got far more clicks, but not measurably more leads.
| Capability | What 28,674 Popupsmart campaigns showed | Popupsmart | Sleeknote |
|---|---|---|---|
| Gamified popups | Spin-to-win and other gamified popups get far more clicks (7.33% vs 1.87% of displays, median campaign; the spin itself counts as a click), but do not collect measurably more email or phone leads than plain signup popups. | Every plan, free included | Gamification add-on |
| Exit intent | No statistically reliable advantage: popups on the most sensitive exit-intent setting converted 1.10% vs 0.78% without exit intent (median campaign), a gap that could be chance. | Every plan, free included | Every plan |
| Multi-step forms | Multi-step forms show no measurable conversion advantage over single-step forms once step-1 clicks without contact details are excluded. | Every plan, free included | Every plan |
| New and returning visitors | Popups targeted at new visitors only convert 1.13% vs 0.77% for popups shown to everyone. | Every plan, free included | Every plan |
| Display frequency | The first two times a visitor sees a popup in a week convert at similar rates (1.33% and 1.22% of displays, pooled); from the third view conversion falls, and from the sixth view it is 0.41%, 31% of the first-view rate. | Every plan, free included | Every plan |
| Traffic source | Visitors arriving from an email or SMS campaign convert on popups at 1.81% vs 0.74% for visitors from organic search. | Every plan, free included | Referral and UTM rules, every plan |
| Page targeting | Popups on cart and checkout pages convert 4.57% vs 1.07% on the home page (median campaign); blog pages convert 0.23%. | Every plan, free included | Every plan |
| Autoresponder email | Among businesses whose popups collect an email or phone number, 16% connect an external tool and 64% turn on the built-in autoresponder email. | Every plan, free included |
Rates are per popup display. "Median campaign" means half the campaigns did better and half did worse. Each line is quoted from the benchmark with its qualifiers: where it says a gap could be chance, treat it as a lean, not a rule. The benchmark measured Popupsmart popups, so it shows what a feature did there, not what it does inside Sleeknote. Sleeknote's 132% is its own figure, from its home page; its page for AI assistants gives it as "2× the conversions of standard popups" across 26,270+ campaigns. Plans as each company's pages listed them on 27 Sep 2026.
The method, the full data and every statement: the 2026 popup conversion benchmark report.

G2 has only a handful of Sleeknote reviews, written between 2019 and 2026. Its reviewers praise a quick setup without developers, an editor that is easy to use and to customize, and the templates; two credit it with more sales or conversions, and one reviewer each names the HubSpot integration, the price and page speed. The complaints are audience settings that took trial and error, a back end with many windows, design tools that could be more modern, and analytics that could go deeper.

Reviewers most often praise how easy Popupsmart is to use and to set up without a developer, then its design options, its targeting and the leads it brings. Their complaints centre on limits: design options they would like wider, the free plan and pageview caps, the price step from free to paid, missing features and reporting depth.

How we made this comparison
Written from experience
We have built and sold Popupsmart, a popup builder, since 2018. That tells us what decides a purchase in this category: how a tool bills, what its free plan holds back, where it sends a lead, and what its users say. Those are the rows on this page.
It also makes Popupsmart one of the two products compared here. So nothing on the page rests on our word alone: every figure comes with its source and the date we read it.

The companies' own pages
Sleeknote's plans and features were read live from sleeknote.com on 27 Sep 2026, from a US location, as a buyer sees them: its pricing page, its features page, its integrations page, its home page, its page for AI assistants, its help center, its Shopify App Store listing, its Capterra reviews and its Trustpilot reviews.
Popupsmart's figures come from our pricing page and our help center. A feature a company's own pages don't list shows as "Not listed", not as missing.
G2's reviews
On 27 Sep 2026 we collected every review of both products on G2: all 6 of Sleeknote's and all 141 of Popupsmart's. An AI assistant read each one in full and sorted what it praises and criticises into themes, counting a review once per theme. No person has checked every tag. The ratings and review counts are G2's.
The quotes are verbatim, checked word for word against G2, and each links to its review with the labels G2 gives it: organic or invited, incentivized or not. Reviews reach G2 in different ways, so each product's source line says how many are which, and when they were written.
We re-read the companies' pages and G2 at least every 90 days, and the dates on this page move when we do. If a figure here is out of date, tell us through our contact page.
