Feature-by-Feature Comparison
Marketing Automation & Campaigns
Winner: Klaviyo. Deeper automation with predictive triggers. Brevo's automation is adequate but less advanced. Sequenzy leads for SaaS with AI optimization.
| Feature | Klaviyo | Brevo | Sequenzy |
|---|---|---|---|
| Drip Sequences | Yes — advanced flows | Yes — visual workflows | Yes — AI-optimized |
| Behavioral Triggers | Yes — 50+ e-commerce events | Yes — basic triggers | Yes — AI-enhanced triggers |
| User Segmentation | Yes — predictive segments | Yes — standard filters | Yes — AI-powered segments |
| A/B Testing | Yes — multivariate | Yes — basic A/B | Yes — auto-optimizing |
| Cart Abandonment | Yes — with product blocks | Yes — basic | No — SaaS focused |
| SMS Campaigns | Yes — built-in | Yes — built-in | No |
| No | Yes — built-in | No | |
| Send-Time Optimization | Yes — smart sending | Partial — basic | Yes — AI-driven |
Klaviyo's automation engine is purpose-built for e-commerce with triggers based on purchase behavior, predicted next order date, and customer lifetime value tiers. Brevo's automation handles standard scenarios (welcome series, abandoned cart) but lacks the e-commerce intelligence layer. Sequenzy targets SaaS lifecycle events with AI-powered optimization rather than e-commerce events.
API & Developer Experience
Winner: Klaviyo. More comprehensive APIs and SDKs. Brevo's API is functional but documentation lags behind.
| Feature | Klaviyo | Brevo | Sequenzy |
|---|---|---|---|
| API Design | REST — comprehensive | REST — functional | REST — solid, SaaS-focused |
| Official SDKs | Python, Node.js, Ruby | Python, Node.js, PHP, Java | Node.js, Python, REST |
| Transactional API | Separate product | Yes — included | Yes — included |
| Webhooks | Yes — extensive | Yes | Yes — including billing events |
| Documentation | Excellent | Good | Good — with SaaS examples |
| SMTP Relay | No | Yes — included | Yes |
| Batch Operations | Yes | Yes | Yes |
| Rate Limits | Generous | Moderate | Generous |
Klaviyo's API is built around e-commerce data ingestion — events, profiles, and catalog management are all well-documented. Brevo has a broader API surface (including transactional email, SMS, and WhatsApp) but the documentation is not as polished. A notable Brevo advantage is the included SMTP relay, which is useful for WordPress and legacy application email.
Deliverability & Infrastructure
Winner: Klaviyo. More consistent deliverability with smart sending. Brevo varies by plan. Sequenzy separates streams.
| Capability | Klaviyo | Brevo | Sequenzy |
|---|---|---|---|
| DKIM Setup | Yes — guided | Yes — guided | Yes — automatic |
| SPF Configuration | Yes | Yes | Yes |
| DMARC Support | Yes | Yes | Yes |
| Dedicated IP | Yes — higher plans | Yes — add-on ($250/yr) | Yes — on paid plans |
| Smart Sending | Yes — prevents over-emailing | No | Yes — AI-driven pacing |
| Stream Separation | Partial | Partial | Yes — separate streams |
| Inbox Placement | Very good (97%+) | Variable (90-96%) | Very good (97%+) |
Klaviyo invests heavily in sender reputation management, and its smart sending feature automatically prevents over-emailing individual contacts. Brevo's deliverability is more variable — the free and lower-tier plans share IP pools, which can be affected by other senders' reputations. Dedicated IPs on Brevo cost extra ($250/year). Sequenzy separates marketing and transactional streams within a single platform for consistent deliverability.
Integrations & Ecosystem
Winner: Klaviyo for e-commerce. Sequenzy for SaaS billing. Brevo has a growing but smaller ecosystem.
| Integration | Klaviyo | Brevo | Sequenzy |
|---|---|---|---|
| Shopify | Yes — deepest integration | Yes — basic plugin | No |
| WooCommerce | Yes | Yes — plugin | No |
| Stripe | Partial — via Zapier | Partial — via Zapier | Yes — native integration |
| WordPress | Partial | Yes — strong plugin | Partial |
| Zapier | Yes | Yes | Yes |
| CRM Built-in | No | Yes — included | No |
| Analytics Platforms | Partial | Partial | Yes — native Mixpanel, Amplitude |
| Total Integrations | 300+ | 150+ | Growing ecosystem |
Klaviyo's integration ecosystem is unmatched in e-commerce. Brevo compensates by including more built-in features (CRM, transactional email, SMS, WhatsApp) that reduce the need for external integrations. Sequenzy differentiates with native billing platform integrations that neither Klaviyo nor Brevo offer, making it ideal for subscription businesses.
Pricing Comparison
Klaviyo
Contact-based. Scales steeply.
Brevo
Volume-based. Very affordable.
Sequenzy
Volume-based. AI automation included.
Cost at Scale: Side-by-Side
| Scenario | Klaviyo | Brevo | Sequenzy |
|---|---|---|---|
| 1K contacts, 5K emails/mo | $30/mo | $0 (free) | $19/mo |
| 5K contacts, 25K emails/mo | $100/mo | $25/mo | $19/mo |
| 10K contacts, 50K emails/mo | $150/mo | $65/mo | $49/mo |
| 25K contacts, 125K emails/mo | $400/mo | $65/mo | $99/mo |
| 50K contacts, 250K emails/mo | $700/mo | ~$150/mo | $199/mo |
Important: Brevo's pricing advantage is dramatic — at 50K contacts it costs roughly 80% less than Klaviyo. However, Brevo lacks the predictive analytics and deep e-commerce integration that justify Klaviyo's premium for revenue-focused stores. Sequenzy at $19/mo offers the best value for SaaS companies that need AI-powered automation rather than e-commerce features.

Who Should Choose What
Shopify store investing in data-driven growth
You want predictive CLV modeling, product recommendations in emails, and the deepest possible Shopify integration. The higher cost pays for itself through increased revenue per customer.
Small business needing email + SMS + WhatsApp on a budget
You want multi-channel marketing with the widest channel support (including WhatsApp) at the lowest cost. You do not need advanced e-commerce analytics or predictive modeling.
SaaS company needing billing-triggered email with AI optimization
You run a subscription business and need email sequences triggered by trial events, billing changes, and feature usage. AI handles optimization. $19/mo with native Stripe integration.
European company prioritizing GDPR compliance
Based in Europe and need a platform with strong GDPR compliance built in, EU data hosting options, and support for WhatsApp marketing which is more popular in European markets.
DTC brand wanting email + SMS with unified flows
You want email and SMS in a single automation flow — for example, sending an email about an abandoned cart, then following up with an SMS if not opened. Klaviyo handles this natively.
Team wanting AI to handle email optimization automatically
You do not have time to manually set up A/B tests, analyze results, and optimize sequences. Sequenzy's AI automatically tests variants, adjusts send times, and improves content — hands-free optimization starting at $19/mo.
Other Alternatives to Consider
Other affordable email platforms
- MailerLite — Even cheaper than Brevo starting at $10/mo. Clean interface and good deliverability. Best for simple email marketing.
- Moosend — Budget-friendly at $9/mo with decent automation. Smaller ecosystem but good value.
- GetResponse — Email + webinars + landing pages starting at $19/mo. Good for teams wanting built-in webinar capability.
- Mailchimp — Household name. Easy to start but gets expensive and limited at scale.
Other e-commerce email platforms
- Omnisend — E-commerce multi-channel (email + SMS + push). More affordable than Klaviyo. Strong Shopify integration.
- Drip — Simpler e-commerce automation. Strong WooCommerce support. Clean interface.
- ActiveCampaign — Email + CRM. More versatile than both Klaviyo and Brevo. Good for sales-led businesses.
- Sequenzy — Best for SaaS (not e-commerce). AI-powered sequences starting at $19/mo with native billing integration.
The choice between Klaviyo and Brevo often comes down to whether you need depth or breadth. Klaviyo offers the deepest e-commerce email capabilities but at a premium. Brevo offers the broadest channel support at the most affordable price. For SaaS companies that arrived here exploring email options, Sequenzy at $19/mo is purpose-built for subscription businesses with AI optimization that neither Klaviyo nor Brevo provides.

Frequently Asked Questions
Is Klaviyo or Brevo better for e-commerce?
Klaviyo is significantly better for e-commerce. It has the deepest Shopify integration, predictive analytics, product recommendations, and e-commerce-specific automation flows. Brevo has basic e-commerce plugins but lacks predictive CLV modeling, dynamic product blocks, and the depth of e-commerce data analysis that Klaviyo provides.
Which is cheaper, Klaviyo or Brevo?
Brevo is much cheaper. Its free tier includes 300 emails per day (about 9,000/month) and paid plans start at $25/mo for 20,000 emails. Klaviyo's free tier is only 250 contacts, and paid plans start at $20/mo for just 500 contacts, scaling steeply to $700+/mo at 50K contacts. For SaaS companies, Sequenzy at $19/mo offers AI-powered automation at an even better value than Brevo.
Can Brevo replace Klaviyo for Shopify stores?
Brevo can handle basic email marketing for small Shopify stores, but it cannot replace Klaviyo's deep Shopify integration. Klaviyo syncs product catalogs in real-time, provides predictive customer lifetime value scoring, and offers dynamic product recommendation blocks in emails. Brevo's Shopify plugin is more basic and lacks these advanced features.
Does Brevo have better multi-channel support than Klaviyo?
Yes. Brevo supports email, SMS, WhatsApp, and live chat in a single platform with unified pricing. Klaviyo supports email and SMS but charges separately for SMS credits and does not offer WhatsApp or chat. For businesses that need WhatsApp marketing (common in Europe and Asia), Brevo is the better choice.
Which has better deliverability, Klaviyo or Brevo?
Klaviyo has more consistent deliverability. Its smart sending feature prevents over-emailing, and dedicated IPs are available on higher plans. Brevo's deliverability can be inconsistent, especially on the free and lower-cost plans where shared IP pools may include lower-quality senders. Sequenzy separates marketing and transactional sending streams for optimal deliverability across both types.
Is Brevo good for SaaS companies?
Brevo works for basic SaaS email needs but is not purpose-built for it. It lacks native Stripe integration, SaaS lifecycle automation, and product usage triggers. For SaaS-specific email marketing, Sequenzy ($19/mo with native billing integration and AI-powered sequences) or Loops (SaaS-native visual builder) are better options.
Does Klaviyo include a CRM like Brevo?
Klaviyo includes customer profiles with purchase history and predictive data, but it is not a full CRM. Brevo includes a basic CRM with deal pipelines and contact management. For a comprehensive CRM + email solution, HubSpot or ActiveCampaign are stronger choices. Neither Klaviyo nor Brevo offers the depth of a dedicated CRM like Salesforce.
Which is better for small businesses on a tight budget?
Brevo is the clear winner for budget-conscious small businesses. Its free tier is generous (300 emails/day), and paid plans starting at $25/mo include more email volume than Klaviyo at any comparable price point. Klaviyo only makes financial sense when its advanced e-commerce features directly drive measurable revenue increases.
What are the best alternatives to Klaviyo and Brevo?
For e-commerce: Omnisend (affordable multi-channel), Drip (simpler automation), Mailchimp (basic and easy). For SaaS: Sequenzy (AI-powered at $19/mo), Loops (SaaS-native), Customer.io (data-driven at $100/mo+). For all-in-one marketing: ActiveCampaign (email + CRM), HubSpot (full marketing suite). For budget options: MailerLite ($10/mo), Moosend ($9/mo).
Can I use Brevo for transactional emails alongside Klaviyo for marketing?
Yes. A common pattern is Klaviyo for marketing automation and Brevo for transactional emails, since Brevo's transactional email API is included in its pricing and performs well. This gives you Klaviyo's e-commerce marketing power plus affordable transactional delivery. Alternatively, Sequenzy handles both marketing and transactional email in a single platform with separated streams.
