🔍 What Makes High-Converting Pop-Ups Work?
Spoiler alert: People don’t hate all Pop-Ups. They hate bad ones, especially those that:
- Interrupt too soon
- Look terrible on mobile
- Offer no real value
High-converting Pop-Ups always tick these boxes:
- ✅ Clean design for both mobile and desktop
- ✅ Clear, simple value proposition
- ✅ Smart timing (not instant!)
- ✅ Relevant, time-sensitive offer
- ✅ Easy-to-complete form (email only is fine!)
📱 Always Design Desktop and Mobile Pop-Ups Separately
This is the #1 mistake brands make. Mobile users navigate differently, and your Pop-Up must reflect that.
Why mobile needs its own setup:
- Smaller screens demand bigger fonts (16px minimum)
- Click areas need to be larger and thumb-friendly
- Keep content short and CTA visible without scrolling
🛠 In Klaviyo:
Create mobile- and desktop-specific versions using the form editor. It lets you fine-tune layout, copy, and triggers per device in order to get High-converting Pop-Ups.
🧠 Write a Headline That Converts in Seconds
Your pop-up headline has about 2 seconds to grab attention.
Winning examples:
- “Unlock 10% Off Your First Order”
- “Be First to Shop Our Spring Drop”
- “Free Shipping? It’s All Yours”
Avoid weak CTAs like “Join our newsletter” — they’re vague and boring.
🧾 Keep It Short and Sweet
The fewer fields, the better. Long forms = lower submit rates.
Best practice:
- Email (required)
- First name (optional)
Need more data like birthdays or phone numbers? Create a separate pop-up for returning subscribers or use post-sign-up flows for SMS/WhatsApp capture.
🔘 Use a Clear, Compelling CTA
Your call-to-action button should:
- Be high contrast and visually clear
- Use action-focused language like:
- “Get My Discount”
- “Unlock Free Shipping”
- “Join the Club”
Avoid “Submit.” It’s dull and doesn’t convert.
⏰ Nail the Timing (Don’t Show It Instantly)
Timing can make or break your pop-up. Let users browse before prompting.
Recommended triggers:
- 15–20 seconds delay
- Scroll depth of 30%
- Exit intent (for desktop)
Test what works best—timing should be adapted to your brand and user behaviour.
🧪 A/B Test Everything
Every part of your pop-up is testable in Klaviyo, Mailchimp or similar platforms.
Test elements like:
- Discount vs. free shipping
- Image vs. no image
- Different CTA text
- Mobile-only vs desktop-only campaigns
Even small tweaks can boost conversions significantly.
