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.

Choose Brevo if

  • Solo creators starting out — the free plan needs no credit card and is positioned for individuals building an online presence
  • Small teams sending across channels: Starter covers email and transactional messages with the drag-and-drop editor, templates, forms and advanced segmentation
  • Businesses ready to automate: Standard adds unlimited multi-step automation workflows and A/B testing on top of Starter

Skip Brevo if

  • You need SMS included — Brevo sends SMS but the credits are sold separately from the plan
  • You want your logo-free sending on the cheapest tier: removing the Brevo logo is a paid item rather than a default
  • Your volume is unpredictable — Starter is quoted from 5,000 emails per month and the plan price moves with the send volume you pick

Choose Klaviyo if

  • Ecommerce stores starting a list — the free plan covers 250 profiles and 500 emails a month
  • Teams that want email and SMS from the same profile data
  • Shops already on Shopify or WooCommerce, where the integration does the work

Skip Klaviyo if

  • Your list is real — 250 profiles is a starting allowance, and the price rises with contact count from there
  • You need a figure before signing up: Klaviyo does not publish its paid tiers on the pricing page, only an estimate builder
  • You send SMS heavily; mobile messages are metered separately
