By Alex Chen, SaaS Analyst · Updated April 11, 2026 · Based on hands-on testing + 10,400 reviews
30-Second Answer
Choose Klaviyo if you run a Shopify or WooCommerce store — its predictive analytics, revenue attribution, and behavioral segmentation are unmatched for driving e-commerce revenue. Choose Brevo if you need affordable multi-channel marketing (email + SMS + WhatsApp) or send high-volume transactional emails. Klaviyo wins 4-2 on features, but Brevo can be 5x cheaper for large contact lists.
Our Verdict
Klaviyo
- Predictive CLV and churn analytics
- Deep Shopify/WooCommerce integration
- Revenue-attributed reporting per flow
- Expensive for large lists ($150/mo for 10k contacts)
- No WhatsApp support
- Overkill for non-e-commerce businesses
Deep dive: Klaviyo full analysis
Features Overview
Klaviyo is the e-commerce email platform. Its deep Shopify integration syncs every customer action — browse, add-to-cart, purchase, refund — and turns that data into predictive analytics like Customer Lifetime Value and churn risk scoring. Pre-built flows (abandoned cart, win-back, post-purchase) generate revenue on autopilot. Most Klaviyo users attribute 20-30% of total store revenue directly to their email flows.
Pricing Breakdown (April 2026)
| Contacts | Price | Key Features |
|---|---|---|
| Up to 250 | $0 | 500 emails/month, basic flows |
| 1,001-1,500 | $45/mo | Unlimited emails, all features |
| 10,000 | $150/mo | Full analytics, predictive features |
Who Should Choose Klaviyo?
- Shopify and WooCommerce stores doing $10k+/month revenue
- DTC brands focused on repeat purchases and customer retention
- Teams wanting revenue attribution per email flow
- Stores needing predictive analytics (CLV, churn risk)
Brevo
- Volume-based pricing — 5x cheaper for large lists
- Email + SMS + WhatsApp in one platform
- Excellent transactional email support
- No predictive analytics (CLV, churn)
- E-commerce integrations are basic vs Klaviyo
- Revenue attribution is limited
Deep dive: Brevo full analysis
Features Overview
Brevo (formerly Sendinblue) is the multi-channel marketing platform that prices by email volume instead of contacts. This pricing model is a significant advantage for businesses with large lists that email infrequently. It combines email, SMS, WhatsApp, and chat in one dashboard. Its transactional email API handles order confirmations and password resets at scale — something Klaviyo doesn't focus on.
Pricing Breakdown (April 2026)
| Plan | Price | Key Features |
|---|---|---|
| Free | $0 | 300 emails/day, unlimited contacts |
| Starter | $25/mo | 20,000 emails/month, no daily limit |
| Business | $65/mo | Marketing automation, A/B testing, phone support |
Who Should Choose Brevo?
- Businesses with large lists but low email frequency
- Teams needing email + SMS + WhatsApp in one platform
- Companies sending high-volume transactional emails
- Budget-conscious B2C businesses outside e-commerce

Which do you use?
Who Should Choose What?
→ Choose Klaviyo if:
You run a Shopify or WooCommerce store and want revenue-attributed reporting, predictive analytics like CLV and churn prediction, and the most powerful behavioral segmentation for e-commerce.
→ Choose Brevo if:
You have a large contact list but send infrequently (volume pricing saves money), need multi-channel outreach including SMS and WhatsApp, or send high-volume transactional emails at scale.
→ Consider neither if:
You're a solo creator or blogger — Mailchimp or ConvertKit are simpler and cheaper for basic newsletter use cases. Don't pay for e-commerce features you won't use.

Frequently Asked Questions
Editor's Take
Here's what I tell every store owner who asks: if your Shopify store does over $10k/month, just get Klaviyo. The predictive analytics and abandoned cart flows will pay for themselves within a month. But if you're running a service business with a 50k contact list and only send a weekly newsletter? Brevo at $25/month is a no-brainer vs Klaviyo's $700/month for the same list size. The tool depends on the job.
