Mailchimp vs Brevo
This comparison is built from three datasets we maintain for every catalog service: documented pricing captured from the vendors' own configurators, the documented-feature matrix compiled from vendor documentation, and user ratings from G2, Capterra and Trustpilot — each value dated at its capture. Neither service has a measured deliverability score yet; we compare only what the data supports.
Editorial verdict — who fits whom
This pairing splits on budget shape and channel breadth. At 1,000 contacts the entry gap is modest — Mailchimp Essentials at $27/mo against Brevo Starter at $17/mo (checked 2026-08-19) — but at 50,000 contacts it turns structural: Brevo's Standard step stays at $69/mo because Brevo prices on email volume, while Mailchimp Standard reaches $450/mo (checked 2026-08-21). Brevo also documents more of the 60 capabilities we track — 46 yes-cells to Mailchimp's 39, with no undocumented items (checked 2026-08-21).
Mailchimp fits teams that want the category's most widely reviewed platform — 32,152 aggregator reviews averaging 4.32/5, against Brevo's 13,315 at 4.26/5 (checked 2026-08-21/22) — and its large integration ecosystem. Brevo fits contact-heavy senders and multi-channel teams that want documented chat, SMS and transactional email alongside campaigns, and care most about cost at list scale. Neither carries a measured InboxRatio deliverability score yet.
