Is Omnisend good enough for serious ecommerce?
For stores doing under $100K/month where email is important but not the primary revenue driver, yes. Omnisend has solid Shopify integration, pre-built ecommerce flows, and adequate segmentation. Above $100K/month where email drives 20-40% of revenue, Klaviyo's analytics and segmentation justify the premium.
Which has better Shopify integration?
Klaviyo's is deeper — real-time sync, predictive analytics (CLV, churn risk), and revenue attribution per email/flow. Omnisend's Shopify integration is solid for campaigns and basic automation but lacks predictive features.
Does Omnisend have SMS?
Yes, built into all paid plans (SMS credits purchased separately). Klaviyo also includes SMS on email+SMS plans. Both support email + SMS automation workflows.
Can I migrate from Omnisend to Klaviyo later?
Yes. Both support CSV export/import. Klaviyo has a migration tool. You'll need to rebuild automations (flows) since they use different builders. Many stores start on Omnisend and upgrade to Klaviyo as revenue grows.
