Be Juliet review for Klaviyo: Email Marketing & SMS

Feb. 18, 2026

Klaviyo is hands down one of the most powerful email and SMS platforms available for Shopify. The segmentation, automation, and data depth are best-in-class. When it’s set up properly, it can absolutely drive meaningful revenue. That said, it really shines only if you have someone actively managing it. To get full value, you need consistent flow optimization, campaign strategy, list hygiene, testing, and performance monitoring. It’s not a “set it and forget it” tool, it rewards attention and strategy. I’d also love to see more flexibility in the pricing structure. When performance fluctuates month-to-month, the fixed pricing model can feel slightly disconnected from results. A structure that better reflects engagement or revenue impact would make it even stronger. Overall, it’s still the best tool in the space hands down, just make sure you’re ready to invest the time (or team) to unlock its full potential.
