‍

‍

Considerations before going with Klaviyo

Klaviyo's pricing scales with your subscriber count, which can become expensive as your list grows. The platform's primary focus is on email marketing rather than dedicated popup optimization, so while the forms are functional, they may not have the conversion optimization features of specialized tools. 

The learning curve can be steep for new users trying to leverage all the advanced segmentation features.

"

"I was expecting Alia to be similar to Klaviyo, maybe slightly better. But it was significantly better. From my end, it was an immediate 'let's roll it out on our other brands.'"

‍

Considerations before going with Justuno

While Justuno offers a free plan, the 2,000 monthly visitor limit is quite restrictive for growing businesses. More advanced features like custom segmentation and workflow automation require higher-tier plans, starting at $99/month. The platform's comprehensive nature also means there's a steeper learning curve compared to simpler popup solutions, potentially requiring more time investment for setup and optimization.

Considerations before going with WooHoo

‍

Considerations before going with Popupsmart

Popupsmart's free plan is quite limited with just one popup and 5,000 pageviews per month. Email quota limits (emails sent through the platform) may constrain larger mailing list growth without upgrading plans. While the AI popup builder is powerful, it may require human tuning to perfectly match your brand voice and messaging strategy.
