Popupsmart vs OptinMonster vs OptiMonk:
Which Popup Tool Is Right
for You in 2026?

Popupsmart's free plan is capped at 5,000 monthly pageviews, one live popup, and 100 email sends per month, with Popupsmart's own branding shown, enough to run a single low-traffic site but not much more. Paid plans start at $39/month (Basic), and A/B testing, one of Popupsmart's core features, isn't unlocked until the $69/month Advanced tier.

Unlike Popupsmart, OptinMonster has no free plan at all; instead of a trial, it offers a 14-day money-back guarantee once you've paid. Paid plans start at $21/month (Basic), with three of its most distinctive capabilities gated behind successively higher tiers: A/B testing needs Plus ($57/month), Exit-Intent needs Pro ($87/month), and Shopify integration needs Growth ($147/month). A first-year promotional rate as low as $7/month appears prominently on OptinMonster's pricing page, but that's a 12-month-only discount, not the standing rate.

OptiMonk's free plan carries no feature gating: every feature is included, capped only by 10,000 monthly pageviews and one domain, enough to run a low-traffic site with the same feature set as the paid tiers. Paid plans start at $29/month for Essential. OptiMonk also offers an annual pricing option at $19/month ($228 billed yearly). Higher tiers add more domains as you go up.

Popupsmart tests one campaign against variants of itself. You add the variants, split traffic between them (say, 50/50), and pick a winner manually or by lead count, interaction rate, or conversion rate. It's locked behind the $69/month Advanced tier, and Popupsmart's help docs don't mention a separate "split URL" or "control group" mode.

OptinMonster works the same way: it randomly assigns visitors to Campaign A or an enabled variant, testing one variable at a time. It unlocks one tier lower, at $57/month (Plus). Like Popupsmart, OptinMonster doesn't document a separate control-group or split-URL mode either.

OptiMonk documents three separate testing modes. A Campaign test pits different campaigns against each other. A Control group test holds back a group entirely, to measure a campaign's real impact against showing nothing at all. And a Multivariate test lets you test multiple elements at once.

Popupsmart advertises 500+ templates. Its campaign types include Fullscreen, Lightbox, Floating Bar, Video Popup, and Multi-Step formats, plus a spin-wheel gamification option.

OptinMonster's library is the largest of the three at 700+ templates, more than Popupsmart's 500+, and it covers the widest range of campaign types. Content lockers, coupon wheels, "Playbooks," and after-post optins sit alongside the standard lightbox, floating bar, and fullscreen formats.

OptiMonk's library is the smallest of the three by count, with 300+ templates organized into 30+ use-case-based families rather than a flat list. Campaign types include Classic Popup, Sidemessage, Sticky Bar, Fullscreen, Embedded Content, and Survey, plus three gamification formats: Lucky Wheel, Scratch Card, and Pick-a-Present.

Popupsmart's AI Popup Builder is prompt-based: you describe what you want, and it generates text, an image, and a call-to-action for a full popup in one pass. It doesn't analyze your site's colors, logo, or fonts to get there, so it works as a fast starting point that still needs manual brand adjustments. Popupsmart's Smart Mode is a separate AI-branded targeting feature, predicting the best audience, timing, and trigger for a campaign automatically.

OptinMonster's AI, branded Smart Optimizations, works differently. It revises copy already sitting inside a text block, offering around five rewritten alternatives per click, rather than generating a popup from a prompt. OptinMonster's own documentation describes this as improving existing copy, not generating it from scratch, a narrower scope than Popupsmart's prompt-to-full-popup generation.

OptiMonk's AI Wizard analyzes a submitted URL and builds a full campaign automatically, and a separate AI Editor lets you request copy changes in plain language afterward. Smart Analytics applies AI-based insights to campaign revenue data. OptiMonk also has a Dynamic Product Recommendations feature for personalized product suggestions, though it isn't described using the word "AI" on OptiMonk's own features page, so it's listed here as personalization rather than an AI feature.

Popupsmart's native Shopify app syncs collected emails and phone numbers into Shopify's Customers list. Its discount-code handling depends on which coupon type you choose. Three of its four modes reuse or pull codes that already exist in your Shopify store. A fourth mode, "Dynamic unique," has Popupsmart generate a new code per visitor and push it to Shopify automatically.

Unlike Popupsmart, OptinMonster's Shopify (and WooCommerce) integration doesn't handle discount codes or customer syncing at all. It's a display and targeting integration only: it reads cart and product-view data so campaigns can be shown conditionally, like "cart total over $50" or "product X viewed." It doesn't sync customer, order, or product records, and it doesn't generate or manage discount codes natively; that requires a separate Zapier connection.

OptiMonk's native Shopify app can create new fixed discount codes, or recognize ones that already exist for display purposes. It can also auto-generate a unique one-time code per visitor, forwarded to Shopify at checkout with an auto-redeem option. Customer data isn't automatically forwarded into Shopify's customer list without manual setup. A separate Dynamic Customer Tags feature pushes tag data one-directionally into Shopify, based on survey answers. Order, revenue, and product catalog data flow the other way: order and revenue sync hourly from Shopify into OptiMonk's own analytics, and its Product Element pulls each product's image, name, price, and SKU directly from a connected Shopify store.

Worth noting: Shopify itself blocks apps from showing content on its Checkout, Thank You, and Order Status pages, not any specific tool here. OptinMonster's docs just happen to be the one place that says so in writing; it's not confirmed whether Popupsmart or OptiMonk face the same restriction.

Popupsmart offers email and live chat support, plus a help center and community forum. Support is "Standard" on the free plan and "Priority" from the Basic paid tier up. Its highest named plan, Expert ($132.50/month), also adds CRO Consultancy, one hour of consulting per month; beyond that, larger sites need a custom quote. Its analytics dashboard tracks views, interactions, leads, and conversion rate, broken down by country, referrer, page, device, browser, and screen resolution. A/B results can also be exported to Google Analytics.

OptinMonster doesn't confirm the same support-by-plan split that Popupsmart documents: its support runs through an email and ticket system, live chat isn't confirmed to be open on every plan, and no phone support is documented. It also sells a separate paid Setup Service. Unlike Popupsmart's named Expert tier, OptinMonster only offers something similar, personal support and account consultations, through its custom-quote Enterprise plan, not a published tier. Its analytics do tier by plan, though, "Simple" reporting on Basic and "Full" from Plus up, covering impressions, conversions, and conversion rate per campaign, plus revenue attribution and a native Google Analytics sync.

OptiMonk documents live chat support in multiple languages on every tier, including free, with an average reply time it states as under three minutes. The one exception is Premium ($249/month), which adds a dedicated key account manager on top of standard support. Analytics don't change by tier either: it tracks baseline site performance (visitors, orders, revenue, conversion rate) alongside two campaign-specific reports: Assisted Revenue, which attributes revenue directly to a campaign, and Total Revenue, for evaluating A/B tests. Revenue data syncs hourly from Shopify, or pulls from Google Analytics 4 instead.

Popupsmart is the only one of the three with a native email-sending feature. Its Email Autoresponder can send a follow-up email to popup subscribers automatically, without connecting an external email service provider. It includes a customizable subject line, sender name, and reply-to address, plus font and color choices, content blocks, an optional coupon code, and product cards. Other settings include a send-delay timer, a plain-text or HTML editor, and a test-send option. It's scoped to a single automated message per opt-in, not a multi-step drip sequence or newsletter tool.

Unlike Popupsmart, OptinMonster has no native email-sending feature at all. Campaign creation and lead capture are its job; actually delivering any email requires connecting an external ESP such as Mailchimp or Constant Contact as a required setup step, and neither a welcome email nor a follow-up sequence can be sent directly from OptinMonster itself.

OptiMonk's own documentation states leads aren't automatically forwarded anywhere, including into Shopify's own customer list, without connecting a separate integration first. Its integrations page lists standard ESPs (Mailchimp, Klaviyo, ActiveCampaign, and similar) alongside Shopify's own email app, Seguno, as the route to actually sending campaigns to collected leads. No native email-sending feature is documented as built into OptiMonk itself.
