Privy vs Justuno vs OptiMonk: Which Popup Tool Is Right for You in 2026?

All three charge on different logic, so a single side-by-side price doesn't tell the full story. Privy charges twice: a pageview-based fee for its Convert (popup-only) plan starting at $24/month for up to 10,000 monthly pageviews, plus a separate contact-based fee if you want its Starter ($30/month, 1,500 mailable contacts) or Growth ($45/month, adds 1,250 SMS credits) plans. Justuno charges by unique monthly visitors, with a free plan capped at 2,000 visitors and paid plans starting around $39/month. OptiMonk charges by pageviews, with a free plan covering 10,000 monthly pageviews and every feature, and its first paid tier, Essential, at $29/month for 20,000 pageviews.

The free-tier story is less about who has one and more about what's gated inside it. Privy is the odd one out here, with no lasting free plan, only a 15-day trial with no credit card required, after which a paid plan is required to keep campaigns live. Justuno and OptiMonk both offer a permanent free plan capped by volume rather than time, at a similar scale (2,000 visitors for Justuno, 10,000 pageviews for OptiMonk). Where they differ is what that free plan includes: Justuno holds back live chat support and its deepest AI and testing features for paid tiers, while OptiMonk's free plan includes every feature and live chat support with no gating.

Privy's popup template count is the thinnest of the three: only "dozens," organized by display type (popups, flyouts, banners, spin-to-win, landing pages), with a drag-and-drop editor and no stated theme system. Its email and SMS templates tell a different story, with 100+ templates covering both channels, a drag-and-drop email editor, and a streamlined SMS composer, both able to pull in real-time product data, unique coupon codes, and dynamic variables.

Justuno skips a fixed popup template count altogether: its Design Canvas is closer to a blank slate with deep CSS and JavaScript access, paired with 80+ targeting rules to decide who sees which design, an approach that rewards teams with design time to spend. Justuno also includes its own landing page builder, offering full-page or embedded page designs with the same dynamic personalization and targeting as its popups.

OptiMonk publishes 300+ templates organized by use case and goal, plus a theme system that applies a chosen visual style across every campaign. Its AI Wizard reads a store's URL and generates a branded starting campaign, and the AI Editor lets a user request changes in plain language instead of manually rebuilding a section.

Privy's AI Assistant generates email, SMS, and popup headline and offer copy from a simple prompt, and can drop that content directly into campaigns and displays. It's a copywriting tool rather than a design or targeting one though: it doesn't build popup layouts, adapt to visitor behavior, or configure targeting rules, so it sits apart from what the other two offer there.

Justuno's Commerce AI recommends products from a store's catalog using up to 8 algorithms per its current knowledge base (marketing materials cite 5), including upsell, cross-sell, and "complete the look." Its Visitor ID identifies anonymous visitors who haven't filled out any form, and Audience Sync pushes those identified segments into Google and Facebook Ads as custom audiences, both gated to the Flex plan and above.

OptiMonk's AI Wizard and AI Editor build and edit full campaigns: describe what should change and it happens, rather than clicking through a builder. That includes on-site copy itself, since the AI Editor can rewrite any text in a campaign on request, alongside the more targeted Smart Headline Generator for headlines specifically. Dynamic Product Recommendations and Smart Analytics are included on every plan, no separate tier required.

Privy's A/B testing is available on paid plans only, and it works at the element level rather than comparing whole campaigns: you create variations of a single display and test the offer, header, image, design, call-to-action, or targeting and timing settings against each other. Traffic can be split unevenly across variations, and once a test concludes, Privy identifies the highest-converting variation as the winner automatically.

Justuno and OptiMonk both build real control-group testing into the platform on top of multivariate testing. Justuno's multivariate tool compares up to 10 variations across multiple elements and, like Privy, automatically applies the winning variation once a test concludes, though this and control-group testing sit behind its Lite plan and above. OptiMonk includes control group, campaign, split URL, and multivariate testing on every plan including free, but applying the winning variant is a manual step rather than an automatic one.

All three are native Shopify apps available on every plan, including free or trial tiers. Privy holds a 4.5/5 rating from over 4,033 reviews, reflecting its long run on the platform since 2015. OptiMonk sits at 4.7/5 from 433 reviews, and Justuno at 4.6/5 from 649 reviews.

Where they differ is in what happens with the sync. Privy syncs contacts, orders, and cart activity, and auto-applies discount codes at checkout. OptiMonk adds product-level targeting and recommendations built from its own product catalog sync, plus the choice to generate brand-new discount codes or work with existing fixed ones, with auto-redeem either way. Forwarding leads to Shopify's Customer list, though, is a separate, opt-in step limited to name, email, phone, and tags, rather than full order or cart history. Justuno goes furthest of the three, ingesting full order history, continuous product and inventory sync, and complete customer profiles automatically, with Commerce AI recommendations built on that data reserved for the Flex plan and above.

Privy offers email and live chat support on every plan, including during its 15-day trial, and assigns a dedicated customer success manager once an account passes 9,000 contacts. Justuno's free plan doesn't include live chat; that opens up on the Lite plan ($39/month), and a dedicated CRO Strategist is included from Flex ($99/month) and above.

OptiMonk offers live chat on every plan, including the free tier, with an average reply time under 3 minutes, and adds a dedicated key account manager on its Premium plan ($249/month). That access-from-day-one approach shows up in its G2 Quality of Support score of 9.7, ahead of Privy's 8.8 and Justuno's 8.7.

Privy is the only one of the three with built-in email and SMS. Its Starter plan includes a drag-and-drop email builder, campaign scheduling, and automated flows (welcome, abandoned cart, purchase follow-up, win-back), and Growth adds SMS campaigns and automations on top, billed separately by contact count and SMS credits.

Justuno and OptiMonk both leave email and SMS to third-party tools. Justuno integrates with SMS providers like Postscript and SMSbump for text capture, and with standard ESPs for email. OptiMonk connects natively to Klaviyo, Mailchimp, Omnisend, HubSpot, and ActiveCampaign, relying on those platforms to send anything once a popup captures a contact.
