Still deciding between Klaviyo and Omnisend?
Klaviyo and Omnisend both offer a free plan and cover the core email/SMS marketing basics, but they differ in structure. Klaviyo's free plan bundles email, $5 of mobile messages, and AI subject-line generation together at no cost, with limits of 250 profiles and 500 emails/month. Klaviyo also lists a built-in CRM (Customer Hub) not mentioned for Omnisend. Omnisend's free plan caps at 500 emails/month and 250 contacts with no credit card required, and its SMS marketing and AI-powered personalizations are tied to paid tiers (SMS credits across plans, AI specifically on the Pro plan at $41.30/month with the listed discount). Teams that want SMS and AI features included from day one on a free tier may lean toward Klaviyo. Teams comfortable paying for a Standard or Pro plan to unlock more contacts and unlimited emails, and who value marketing automation listed across all Omnisend plans, may prefer Omnisend's tiered structure. Compare current limits directly with each vendor before committing.
