In 2026, both platforms continue to compete fiercely by offering advanced features like AI-powered segmentation, predictive analytics, and omnichannel marketing capabilities. However, they differ substantially in pricing structure, feature availability, and ease of use.
Pricing Comparison: A Critical Factor
Pricing is often the deciding factor between these two platforms, so let’s break it down clearly:
| Feature | Omnisend | Klaviyo |
|---|---|---|
| Free Plan | Up to 250 subscribers | Up to 500 subscribers |
| Starting Paid Price | $20/month | $20/month (or free tier) |

Omnisend Pricing Details
Free Plan: Up to 250 contacts, limited to email and SMS. This is generous for startups testing the platform.
Paid Plans: Starting at $20/month, Omnisend’s pricing is based on subscriber count. A significant advantage is that SMS is included in all paid plans—you only pay per message sent, not for additional platform fees.
Mid-Tier (1,000-5,000 contacts): Expect to pay $40-$80/month with SMS included. This makes Omnisend particularly attractive for businesses wanting unified email + SMS without separate tool costs.
Klaviyo Pricing Details
Free Plan: Up to 500 contacts with basic email functionality. Klaviyo’s more generous free tier is attractive for beginners.
Paid Plans: Email starts at $20/month, but SMS requires separate SMS credits purchased as add-ons (typically $0.01-$0.03 per message). This can significantly increase your total cost of ownership.
Hidden Costs: Advanced features like predictive analytics, advanced segmentation, and dedicated support often require higher-tier plans ($300+ monthly).
