2. Pricing
Klaviyo uses a hybrid pricing model — you pay based on contact count + email volume tier. It's more expensive than Brevo or MailerLite but delivers significantly more e-commerce value.
- Free: 250 contacts, 500 emails/mo
- Email: $20/mo (500 contacts) to $700/mo (100K contacts)
- Email + SMS: $35/mo (500 contacts) + usage
At 5,000 contacts: ~$60/mo for Email, ~$100/mo with SMS. Compare to Brevo at $25/mo — you pay a premium for Klaviyo's e-commerce data capabilities.
3. E-Commerce Integration (The Killer Feature)
Klaviyo's deep integration with Shopify, WooCommerce, and BigCommerce is what sets it apart. It pulls in:
- Product data: Names, prices, categories, images
- Purchase history: What customers bought, when, how much
- Browsing behavior: Products viewed, added to cart, abandoned
- Predictive analytics: Likelihood to purchase, predicted lifetime value
This data powers hyper-personalized campaigns — "You viewed this product, here's 10% off" — that convert at 3-5x the rate of generic email blasts. No other platform comes close to Klaviyo's e-commerce data depth.
4. Segmentation & Data
Klaviyo's segmentation engine is extraordinarily powerful. You can segment by: purchase behavior, product affinity, email engagement, predicted metrics, SMS engagement, and custom events. Segments update in real-time. For e-commerce stores running targeted promotions, this is a game-changer.
5. Automation Flows
Klaviyo has pre-built flow templates for welcome series, abandoned cart, post-purchase, browse abandonment, win-back, and more. The visual builder is clean and easy to use, though less flexible than ActiveCampaign's workflow builder.

6. SMS Marketing
Klaviyo's SMS is built-in, not bolted on. You get a dedicated SMS number, can segment by SMS engagement, and include SMS steps in flows. It's a strong offering, though Brevo's SMS + WhatsApp combination is more versatile for non-e-commerce businesses.
