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.

Measured deliverability

Inbox placement: not yet tested

Neither Mailchimp nor Brevo carries a measured InboxRatio Deliverability Score yet — measured scores publish as test cycles complete, and we never infer a deliverability comparison from pricing, features or user ratings. When both services have completed a seed-list cycle, this section will show their measured inbox-placement results side by side.

How we test deliverability

From our pricing dataset

Pricing side by side

Cheapest paid tier covering each volume, and the functional tier — the cheapest tier with automation, API access and vendor-branding removal all included — captured from the vendors' own pricing configurators on monthly billing.

VolumeMailchimpBrevo

Pricing checked 21 August 2026 · monthly billing, prices as shown by the vendor. Where a vendor has no exact step at a volume, the nearest covering step was captured (noted in the dataset).

Frequently asked questions

Is Mailchimp or Brevo cheaper at 50,000 contacts?

At 50,000 contacts, the cheapest paid Mailchimp tier covering that volume is $385/mo and the cheapest paid Brevo tier is $69/mo — vendor-page prices on monthly billing, last checked 21 August 2026. Which works out cheaper for you also depends on which tier carries the features you need; the side-by-side tables above show both services' entry and functional tiers at each volume.

Do users rate Mailchimp or Brevo higher?

Mailchimp averages 4.3/5 across 32,152 reviews and Brevo averages 4.3/5 across 13,315 reviews on G2, Capterra and Trustpilot (review-count-weighted, checked 22 August 2026). Review-base sizes differ, so read the averages together with the counts. User ratings are context only — never part of our measured Deliverability Score.

What are the main feature differences between Mailchimp and Brevo?

Of the 60 capabilities we track per vendor, Mailchimp and Brevo document 27 of them differently. The comparison table above lists the headline contrasts — cells where one vendor documents a capability the other documents as absent or does not document at all. All marks reflect vendor documentation, not our testing.

Has InboxRatio tested Mailchimp and Brevo's deliverability?

Not yet — both services are in the queue for Cycle 0, our first seed-list test cycle across the whole catalog. Measured inbox-placement scores publish only as test cycles complete, so this comparison deliberately carries no deliverability numbers for either service until then. How we test.
