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.
Omnisend
Omnisend sits in a crowded category but earns its place by making omnichannel marketing genuinely straightforward. Most platforms treat SMS as a bolt-on to email. Omnisend builds a single automation canvas where email, SMS, and push notifications share the same triggers, branching logic, and exit conditions. An abandoned cart sequence can email at hour one, text at hour four, and send a push notification the next morning without needing three separate tools or any duplicated configuration. The free tier is meaningfully generous. Up to 500 emails per day to 250 contacts with no credit card required, which is more runway than most early stores need to figure out whether email is moving the needle. Pricing beyond free scales more predictably than Klaviyo, which makes Omnisend the more cost-effective choice for stores that have not yet hit the revenue level where Klaviyo's analytics depth justifies the premium. Where Omnisend trades off against Klaviyo is in the sophistication of its segmentation and predictive analytics. Klaviyo's ability to forecast churn, predict next purchase date, and build deeply behavioural segments is genuinely ahead of the field. Omnisend covers the standard segmentation use cases well but does not go as far. For most Shopify stores under a few million in annual revenue, that difference rarely matters in practice. For brands running large, complex lists with meaningful LTV variation, it eventually does.
