Frequently Asked Questions
For email-only: Klaviyo is about 1.5-2x more expensive. For email + SMS: Klaviyo can be 3-4x more expensive because SMS is an add-on ($0.01-0.03 per message) versus included with Omnisend. For a store sending 10K SMS/month, Klaviyo adds $100-300/month extra.
Yes, migration is straightforward. Both platforms have import/export tools. Customer data syncs automatically via Shopify. The main work is recreating automation workflows, but Omnisend has templates for all common ecommerce flows. Most stores complete migration in 2-3 days.
Both have excellent deliverability (97%+). Klaviyo has slight edge for large-volume senders (100K+ emails/day) due to dedicated IP options. Omnisend uses shared IPs with rigorous monitoring. For most Shopify stores (<50K emails/day), there's no noticeable difference in deliverability.
Omnisend has 90% of Klaviyo's core ecommerce features. Where Klaviyo wins: Predictive analytics, advanced attribution modeling, and enterprise-grade reporting. For most stores, Omnisend has everything needed: segmentation, automation, A/B testing, SMS, and basic analytics.
Choosing based on features they don't actually need. Many stores pay for Klaviyo's advanced features but only use basic automation. Start with Omnisend (or Klaviyo free), master the basics, then upgrade only when you hit limitations. 70% of stores under $100K/month don't need Klaviyo's premium features.
Technically yes, but not recommended. It doubles costs, confuses customers (duplicate emails), and fragments data. Better to run a 30-day A/B test with both, then choose one. Some enterprise stores use Klaviyo for email and Omnisend for SMS (cost-effective), but this requires careful coordination.
