Brevo vs Klaviyo

A source-aware comparison of pricing, documented capabilities and workflow fit.

Short answer

These lines are generated from the pricing we track, not from a paid placement. How we score tools.

What Brevo is

Brevo combines email campaigns, SMS, automation and a light CRM, priced by emails sent rather than contacts stored. Billing by emails sent rather than contacts stored changes the maths for lists with a large inactive tail. The interface is broad rather than deep, so teams running sophisticated lifecycle programmes usually outgrow the automation builder.

What Klaviyo is

Klaviyo is the smartest marketing automation platform for e-commerce. It uses store data to analyze 'who bought what and when.' This lets you build incredibly detailed automations like 'send a discount to customers who haven't bought in 30 days but have spent over $500.' Known as the 'brain of e-commerce,' it is the top choice for brands looking to turn data into sales.
