Bird vs Klaviyo. Both serve e-commerce. Bird goes further.

Channels
Klaviyo: Email and SMS only. Strong in both — Klaviyo's email deliverability is consistently ranked among the best in the industry, and their SMS capabilities cover shortcodes, toll-free, and branded sender IDs in the US. But the channel coverage stops there. Bird: Email, SMS, WhatsApp, push, RCS, and voice. For markets where WhatsApp is the primary channel — Latin America (70%+ penetration), Southeast Asia, Europe — Bird is the only option. In Brazil alone, WhatsApp reaches 98% of smartphone users, making email-only or SMS-only strategies incomplete.
E-commerce Integration
Klaviyo has best-in-class Shopify integration — deep product catalog sync, predictive analytics on purchase behavior (predicted CLV, churn risk, next order date), and 50+ pre-built flows designed specifically for the Shopify ecosystem. This is Klaviyo's genuine strength — they process over $30B in attributed revenue for Shopify merchants. Bird integrates with Shopify, BigCommerce, WooCommerce, Magento, and 100+ other platforms via native connectors and a REST API. The Shopify integration supports catalog sync, abandoned cart triggers, and purchase events. The integrations are solid but newer than Klaviyo's Shopify-specific features. Where Bird excels is multi-platform e-commerce — if you sell on Shopify and Amazon and your own site, Bird unifies the customer view across all storefront data.
AI & Automation
Klaviyo: AI-powered subject lines, send time optimization, predictive analytics on customer lifetime value, and recently launched AI-generated segments. Good optimization tools that improve existing workflows. Conversion rates typically improve 10-15% with Klaviyo's AI features. Bird: 60+ AI agents that build entire campaigns, segment audiences, write copy, and optimize autonomously. The difference is optimization (Klaviyo) vs. full automation (Bird). Bird's campaign agent can go from a business goal ('increase repeat purchases from customers who bought in Q4') to a live, optimized, multi-channel campaign without human intervention.
Pricing
Klaviyo charges by contact count — whether you email them or not. At 50K contacts: ~$700/month for email only, ~$1,200/month with SMS. At 200K contacts: ~$2,000+/month for email, ~$3,500+ with SMS. Annual cost at 200K contacts: $24,000-$42,000. Bird charges by usage — messages sent, not contacts stored. Store unlimited contacts for free. At equivalent sending volumes (200K contacts, 800K emails/month, 50K SMS/month), Bird typically costs 40-60% less. Annual savings for a mid-size e-commerce business: $10,000-$25,000.
Where Klaviyo excels
If you're a Shopify-first business doing primarily email and SMS in the US market, Klaviyo's deep Shopify integration and e-commerce-specific predictive analytics are genuinely best-in-class. Their pre-built flows for abandoned cart (recovering 3-5% of carts on average), browse abandonment, winback, and post-purchase are battle-tested across 100,000+ stores. Klaviyo's benchmarking data — showing how your flows perform against similar stores — is a unique advantage no competitor matches. The Shopify ecosystem trust is also real: Klaviyo is Shopify's recommended email partner, and the integration depth shows.
E-commerce brand
“We switched from Klaviyo to Bird when we expanded beyond the US. Klaviyo's SMS coverage outside North America was limited, and we needed WhatsApp for our European and LATAM customers.”
Frequently asked questions
Yes. Bird supports direct migration from Klaviyo including contact lists, segments, flow/journey logic, email templates, and historical engagement data. Most Klaviyo migrations complete in 1-3 weeks. Bird's migration team can also recreate your top-performing Klaviyo flows in Bird's journey builder.
Klaviyo charges by contact count ($700/month at 50K contacts for email only). Bird charges by usage — unlimited contacts stored free, pay only for messages sent. At equivalent volumes, Bird is typically 40-60% cheaper. The savings increase at scale because Bird offers volume discounts while Klaviyo's per-contact pricing scales linearly.
Bird offers WhatsApp, push notifications, RCS, and voice as native channels — Klaviyo only supports email and SMS. Bird also includes a built-in CDP, 60+ autonomous AI agents, a unified inbox across all channels, and a visual journey builder that orchestrates across 6 channels. Bird's AI agents can build and optimize entire campaigns autonomously, whereas Klaviyo's AI assists with optimization within existing workflows.
Yes. Bird has a native Shopify integration that supports product catalog sync, abandoned cart triggers, purchase events, and customer data sync. However, if you're exclusively on Shopify and only need email/SMS in the US market, Klaviyo's deeper Shopify-specific features (predictive CLV, store benchmarking, 50+ pre-built flows) may be a better fit. Bird's advantage shows when you need additional channels, international reach, or AI-driven automation.
