Brevo (formerly Sendinblue) and Mailchimp are both pitched as email-marketing platforms, but they answer two different questions. Mailchimp is the one most people have heard of — the friendly, design-led name you reach for when you want campaigns that look good. Brevo is the one people switch to — usually when Mailchimp’s bill starts climbing and they realise they’re paying for contacts they barely email. Put them side by side and the decision isn’t really about features. It’s about how you want to be billed, and whether your tool needs to do messaging jobs — transactional email, SMS — that Mailchimp treats as someone else’s department.

Get the billing question right and the rest of the comparison mostly falls into place.

Honest disclosure: some links below are affiliate links. If you sign up through one I may earn a commission at no extra cost to you. Neither Brevo nor Mailchimp is one of them, so I have no stake in which of the two you pick — everything here is my genuine assessment, including where a cheaper option might serve you better.

Pricing, free-plan limits and billing rules change often on both platforms. Treat the specifics below as the shape of the trade-off, and confirm the current numbers on each provider’s pricing page before you decide.

The core difference in one sentence

Brevo bills you by how many emails you send — and bundles transactional email, SMS and a light CRM into a functional, plumbing-first platform. Mailchimp bills you by how many contacts you store — and leans on a big template library, polished design and a household-name ecosystem to be the friendly marketing front-office.

A fast way to feel the difference: Mailchimp’s pride is its templates and brand — the shop window, the thing your campaigns look like. Brevo’s pride is its billing model and its plumbing — pay for what you send, and send your app’s system emails and texts from the same place. One is built to look good to your readers; the other is built to be cheap and flexible behind the scenes.

Brevo: the send-volume engine

Brevo made its name with one clever idea — charge for emails sent, not contacts stored — and grew it into a broader messaging platform.

Pros:

• Send-based pricing. You pay for how many emails you send, not how many contacts sit in your account. For a big list you email occasionally, that can be dramatically cheaper than a contact-based tool — the exact case where Mailchimp stings most.
• Transactional email and SMS, built in. Brevo handles the automated receipts, password resets and order confirmations your app sends via SMTP or API, plus SMS marketing, in the same account as your campaigns. That’s two messaging jobs in one tool.
• A light built-in CRM and automation. Basic contact management, deals and automation workflows are included, so simple follow-up and lead tracking live alongside your email.

Cons:

• The interface feels functional, not polished. Brevo reads as a capable marketing-and-messaging platform rather than a friendly design tool; its editor and template library are plainer and busier than Mailchimp’s.
• The free plan caps daily sends. Brevo’s free tier is generous on contacts but limits how many emails you can send per day — which catches people out exactly when they want to email everyone at once.
• Support can be slow, and it’s not built to sell. Like Mailchimp, it’s a marketing-and-messaging tool — no real funnels, no hosted courses, no full checkout.

Brevo suits a business that emails a large or uneven list, or one that needs transactional/SMS messaging next to its campaigns, and would rather its bill track sending volume than head-count.

Mailchimp: the design-led marketing front-office

Mailchimp is the default name in email marketing for a reason — it’s polished, approachable and everywhere.

Pros:

• A big template library and a polished editor. Mailchimp makes good-looking campaigns easy, with a deep set of designed templates and a friendly drag-and-drop builder — the strongest design experience of the two.
• Mature reporting and a huge integration catalogue. Reporting is clear and established, and because Mailchimp is so widely supported, most third-party tools integrate with it out of the box. It’s owned by Intuit, which anchors it in a broad business-software ecosystem.
• Instant signup and a familiar on-ramp. You can create an account and start the same day, with no approval wait — and most people have seen the interface before.

Cons:

• Contact-based billing — including contacts you don’t email. You pay by the number of contacts stored, which depending on your settings can include unsubscribed and non-sending contacts. As the list grows, the bill climbs even if your sending stays modest, and list housekeeping starts to matter for cost reasons.
• Automation is light and tier-gated. The deeper automation features sit on higher plans, and even then it’s not a power-automation tool.
• The free plan has been trimmed over the years, and there’s no native transactional/SMTP product in the main plan or SMS in the way Brevo bundles them — transactional sending is a separate paid product.

Mailchimp suits people who value design and familiarity, email their list often enough that contact-based pricing isn’t punishing, and want the household-name tool with the broadest integration support.

Head-to-head: the differences that actually matter

Billing model — the defining difference

This is the whole decision for most people, and it’s a genuine trade, not a winner. Brevo bills by emails sent; Mailchimp bills by contacts stored. If you have a large list you email infrequently — or a list with lots of inactive contacts you’re reluctant to delete — Brevo’s send-based model is usually the cheaper, fairer fit, and Mailchimp’s contact billing is exactly what’s pushing your cost up. Flip the usage pattern, though, and it’s less clear-cut: a smaller list you email very frequently can run into Brevo’s daily-send ceiling and suit Mailchimp’s contact plans fine. Before anything else, write down whether your cost should scale with how many people you store or how many emails you send — that single answer points at one tool.

Design, templates and the editor

Mailchimp wins. A bigger, more polished template library and a friendlier editor make it the better tool for campaigns that need to look designed and on-brand. Brevo’s editor is perfectly usable but plainer and more utilitarian. If the look of your email matters to you, this section favours Mailchimp clearly.

Transactional email and SMS

Brevo, decisively. Brevo bundles transactional email (the system messages your app sends via SMTP/API) and SMS marketing natively, alongside your campaigns. Mailchimp’s transactional sending is a separate paid product, and SMS isn’t its focus. If app-triggered emails or text messaging are part of how you operate, Brevo does in one account what Mailchimp asks you to bolt on — and that can be the entire reason to pick it.

Automation and CRM

A narrow edge to Brevo, but both are light. Brevo includes basic automation, deals and a light CRM in the same tool; Mailchimp’s automation is light too and gated to higher tiers. Neither is a power-automation platform — if you need branching journeys, lead scoring and a real sales pipeline, both will frustrate you, and a dedicated tool like ActiveCampaign is the honest answer. For simple welcome sequences and tagging, either is fine.

Familiarity, ease and ecosystem

Mailchimp wins. Instant signup, a household-name interface most people have seen before, mature reporting and the broadest integration catalogue make Mailchimp the smoother, more familiar on-ramp. Brevo is approachable enough, but it’s the less recognised name with a busier, more functional feel.

Selling products and courses

Neither — and this is the gap they share. Both send campaigns and run light automation, but neither hosts a real course with lessons and progress, neither builds a multi-step funnel with order bumps and upsells, and neither replaces a proper checkout-and-delivery stack. Both quietly assume the actual selling happens in tools you add around them — which is the gap the next section covers.

Where Systeme.io fits

Here’s the part most Brevo-vs-Mailchimp comparisons skip: both are marketing-email tools that don’t actually sell anything. You can pick the perfect one of the two — the right billing model, the nicer templates — and still need a funnel builder, a course host and a real checkout before your first launch. You’d be juggling a send cap or a contact bill and stitching selling tools around it.

If selling is the real goal — a course, a digital product, a funnel that converts — it’s worth knowing a third option exists: Systeme.io bundles email broadcasts and automation alongside sales funnels, course hosting, checkout with order bumps and upsells, and a built-in affiliate program, all in one login with a genuinely free plan that has no time limit. The honest trade-offs: its automation is shallower than either tool’s deeper tiers, it has no dedicated transactional/SMTP product or SMS like Brevo, its templates are plainer than Mailchimp’s library, and its deliverability and reporting tooling are lighter than a sending-focused platform’s. But as one free hub to run and sell a whole small business from, neither Brevo nor Mailchimp competes with it on what you get for $0.

So which should you choose?

Choose Brevo if:

• Your cost should track how many emails you send, not how many contacts you store — a large or uneven list you email infrequently is the classic case.
• You need transactional email (app/order/system messages) or SMS in the same account as your campaigns.
• A functional, fair-priced engine matters more to you than polished design or a household name.

Choose Mailchimp if:

• You email your list often enough that contact-based pricing isn’t punishing, and you value a deep template library and polished, on-brand design.
• You want the familiar, household-name tool with mature reporting and the broadest integration support.
• Instant signup and a recognised interface matter more than send-based billing or built-in transactional/SMS.

Start with Systeme.io if:

• The real goal is to sell — a course, a digital product, a funnel with a real checkout — not just send campaigns.
• You’re early enough that one free all-in-one beats assembling an email tool plus a funnel builder plus a course host.
• You’d rather validate the business first on a free plan and graduate to a specialist email tool later, when sending volume or design depth becomes the actual bottleneck.

A practical shortcut: picture your list a year from now. Ten thousand contacts you email once a month? Brevo’s send-based billing will likely cost less and won’t punish you for keeping the list. A few thousand contacts you email weekly with beautifully designed campaigns? Mailchimp earns its keep. And if the honest answer is “the emails are supposed to point at a course or a checkout that doesn’t exist yet,” then neither email tool is your real bottleneck — start where selling is free.

The honest bottom line

Brevo vs Mailchimp looks like a feature contest, but it’s really a billing-and-purpose contest. Brevo is the better-value engine for anyone whose cost should follow sending volume, and the clear winner if you need transactional email or SMS in one place — at the price of polish and familiarity. Mailchimp is the friendlier, better-designed, more widely-integrated front-office — worth its contact-based bill if you email often and care how your campaigns look. Pick by which describes you: a sending engine that should be billed by sends, or a design-led marketing tool you’ll use frequently. And if the real answer is “it’s meant to fund something I sell,” start where selling is free — a free all-in-one will carry you further for $0 while you prove the model, and either email tool will still be here when its specialism becomes the thing you actually need.
