Privy

Overview and Positioning

Privy is a long-standing popup and on-site conversion app tailored to small and mid-size Shopify stores. Privy focuses on lead capture, cart abandonment, and simple onsite promotions. It is positioned as a low-friction, easy-to-install solution for merchants who need quick results without a steep learning curve.

Key Features and Strengths

• Drag-and-drop popup builder with templates for email capture, discounts, and banners.
• Triggers: exit-intent, time delay, scroll, and page targeting.
• Basic A/B testing for campaigns.
• Built-in email capture flows and basic automation (welcome emails, cart saver).
• Integration with Shopify customer lists and common ESPs (Mailchimp, Klaviyo, Shopify Email).
• Lightweight and fast on storefronts; simple analytics for conversion rates and revenue attribution.

Limitations and Tradeoffs

• Personalization depth is limited compared to enterprise tools; segmentation is basic.
• Advanced experimentation and complex multi-step journeys are not a strong suit.
• SMS capabilities are more limited compared to apps focused on omnichannel (though integrations are possible).
• For high-traffic stores, some merchants report needing more advanced targeting to avoid showing irrelevant popups.

Pricing and Value

• Free plan: available with basic popups and email capture (limits on sends and features).
• Paid plans: starting around $15/month for Growth (adds A/B testing, priority features), with higher tiers around $45/month+ as email/contact volume grows.
• Privy uses contact or send thresholds for higher tiers; exact pricing depends on subscriber counts and features.

Pricing note: figures are accurate as of June 2024 and may vary based on promotions or Shopify App Store offers.

Best For

• Small shops and new merchants who want a simple, inexpensive popup solution.
• Stores that want quick email capture and simple cart recovery without building complex automation.

Klaviyo Signup Forms

Overview and Positioning

Klaviyo is primarily an email and SMS marketing platform. Its Signup Forms feature provides popups, flyouts, embedded forms, and full-page takeover options tightly integrated with Klaviyo profiles and flows. Klaviyo positions forms as part of a data-first lifecycle marketing system, enabling advanced segmentation and flow-based automation.

Key Features and Strengths

• Deep integration with Klaviyo profiles: captured data immediately syncs to Klaviyo lists and properties.
• Advanced targeting using historical behavior and predictive data (lifetime value, predicted churn).
• Signup forms support multi-step capture, properties (e.g., birthdate, preferences), and prefill for returning visitors.
• Seamless use of captured leads in Klaviyo flows, including welcome series and cart abandonment sequences.
• Native A/B testing and analytics within Klaviyo, attribution to revenue through tracked flows.

Limitations and Tradeoffs

• Klaviyo can be overkill if you only need simple popups; it requires familiarity with Klaviyo flows and segmentation to get maximum ROI.
• Pricing of Klaviyo grows quickly as contact lists increase, particularly when adding SMS.
• Form design tools are powerful but slightly more technical than beginner-focused popup builders.

Pricing and Value

• Free tier: up to 250 contacts and limited email sends, including forms.
• Paid plans: start at roughly $20/month for up to 500 contacts (email-only). Adding SMS increases cost; combined email+SMS pricing is higher.
• Klaviyo is cost-effective when popup capture feeds into revenue-driving automation, but expensive if used only for simple popups.

Best For

• Merchants already using Klaviyo or planning to invest in data-driven email/SMS marketing.
• Stores that want advanced targeting and attribution from the first capture through conversion.

• Complexity: learning curve for non-technical users; more configuration is required to get the most out of the platform.
• Cost: pricing tends to be higher than simpler popup apps, making it less attractive to very small merchants.
• For stores that do not need advanced segmentation, Justuno may be more than required.

Pricing and Value

• Trial: free trial or demo typically available.
• Small business plans: starting around $29-$59/month for basic features (approximate and subject to change).
• Pro and enterprise tiers: often $199/month and up, with custom pricing for large volumes and advanced features.

How to Choose

Checklist and decision tree for selecting the best popup app:

1. Purpose: Do you want simple lead capture, conversion-focused personalization, or full lifecycle automation?

• Simple capture and budget-friendly: Privy or Omnisend.
• Advanced onsite personalization and promotions: Justuno or OptiMonk.
• Data-driven lifecycle marketing integrated with email/SMS: Klaviyo Signup Forms.

2. Integration needs:

• If you already use Klaviyo for flows and segmentation, use Klaviyo forms to avoid syncing issues.
• If you want built-in omnichannel messaging (email+SMS) in one product, consider Omnisend.
• If your ESP is separate and you only need popups, Privy or OptiMonk are flexible.

3. Traffic and scale:

• Low-to-medium traffic merchants will be fine with Privy or OptiMonk paid tiers.
• High-traffic or enterprise merchants with multi-store setups may be better on Justuno or high-tier OptiMonk.

4. Budget and ROI:

• If budget is a primary constraint, prioritize free plans and low entry pricing (Privy, Omnisend).
• If you can justify higher spend for better personalization and higher AOV, choose Justuno or Klaviyo to unlock targeted revenue increases.

5. Team and technical resources:

• Small teams or single-operator stores: choose easier, lower-maintenance apps (Privy, Omnisend).
• Marketing teams that can run experiments and configure granular rules: consider Justuno or OptiMonk.

Follow this checklist: match your use case, map integrations, forecast required features as traffic grows, and test with A/B experiments before committing to high-tier plans.

FAQ

Can I Use Multiple Popup Apps on the Same Shopify Store?

You can use multiple popup apps, but it is not recommended. Running more than one popup solution typically causes overlapping messages, degraded page performance, and a poor user experience. If you must, ensure triggers and audience rules are strictly separated.

Which App Captures the Most Accurate Revenue Attribution?

Klaviyo and Justuno are strong at revenue attribution because they integrate deeply with customer profiles and can tie captured emails to flows and orders. Klaviyo is particularly strong at tying captured leads to lifecycle revenue when you use its flows.

Are Popup Apps Bad for SEO or Page Speed?

Popups themselves do not inherently hurt SEO, but heavy scripts and poor configuration can slow page load times. Choose apps known for lightweight scripts (Privy, Klaviyo) and enable asynchronous loading where available. Avoid full-screen intrusive popups on mobile that violate platform guidelines.

Do Popup Apps Support GDPR and Consent Options?

Most reputable popup apps provide GDPR and consent features, including checkboxes and privacy text. However, you must configure them correctly to ensure compliance. Use explicit consent fields for email marketing when required.

Should I Offer Discounts in Popups or Focus on Value Exchange?

Both approaches work. Discounts usually boost short-term conversion and capture, but value exchange (exclusive content, loyalty enrollment, early access) can capture higher-quality leads and protect margins. Test both strategies with A/B tests to see which produces better CLTV.

How Do I Test Popup Performance Effectively?

Run A/B tests with one variable at a time: headline, offer, timing, or targeting. Measure sign-up rate, conversion rate to purchase, and revenue per visitor. Use statistical significance calculators and run tests long enough to capture meaningful traffic segments.
