About
Attentive
Attentive is the SMS and email platform of choice for mid-market and enterprise e-commerce brands. Its two-tap mobile opt-in is the fastest list-building mechanism in the category, and AI-driven send-time optimisation consistently delivers click rates in the 20–30% range that email can rarely match. The platform is deep but not cheap: expect enterprise pricing and a proper onboarding process. It is not the right fit for stores under $500K in annual revenue, where Postscript or Klaviyo SMS will give you 90% of the capability at a fraction of the cost. For brands ready to invest in SMS as a serious revenue channel, Attentive is the benchmark.
Klaviyo
Few platforms have done more to raise the bar for e-commerce email marketing than Klaviyo. What sets it apart from generic email tools is its deep Shopify integration and predictive analytics layer. It can identify customers likely to churn before they actually do, then enrol them in the right retention flow automatically. Segmentation is genuinely powerful: you can slice your list by purchase behaviour, predicted LTV, or browsing history without writing a single line of code. It's the default choice for most serious Shopify brands, though smaller stores should be aware the pricing scales steeply with list size.
