Brevo vs Mailchimp for Small Business (2026)

Brevo and Mailchimp are two of the most common starting points for small business email marketing. Both offer free plans. Both promise easy onboarding. But they have made very different product bets over the past two years, and those differences matter more now than they did in 2024.

Mailchimp has moved upmarket. Its pricing has increased, free plan limits have tightened, and its richer automation and testing tools sit behind higher tiers. Brevo has moved in the opposite direction, bundling CRM, transactional email, SMS, and a broader multi-channel path into a single platform at a lower starting price point. For budget-conscious teams, this gap is significant.

This is not a situation where one tool is objectively better. It depends on your workflow, your volume, and which features you will actually use. This comparison lays out the facts so you can make the call without guessing.

Pricing and plan details below were verified on April 1, 2026 from official Brevo and Mailchimp pricing and help pages.

Pricing is where these two platforms diverge most clearly. Brevo charges based on email volume. Mailchimp charges based on audience size. That distinction shapes everything else.

At the first paid tier, Brevo Starter begins at $9/month for 5,000 emails, while Mailchimp Essentials begins at $13/month and is still priced by contact count. That alone makes Brevo easier to justify for small agencies that collect leads faster than they send newsletters.

The bigger pricing difference is how the bill scales. Brevo's paid tiers step up with monthly send volume, while Mailchimp's monthly plans require you to choose a contact tier and can add overage charges if you exceed your contact or send limits. For a small agency with a growing list and limited budget, Brevo's volume-based model stays easier to defend.

Both platforms offer drag-and-drop email builders. Mailchimp's builder has more template variety out of the box, with over a hundred pre-designed templates organized by industry and campaign type. The editor is polished and intuitive. If you want to send a well-designed campaign quickly without touching code, Mailchimp makes that easy.

Brevo's builder is simpler but functional. The template library is smaller, and the designs are more utilitarian. For teams that mostly send plain-text-style emails, onboarding sequences, or transactional messages, this is fine. If your brand relies on visually rich campaigns with custom layouts, you will notice the difference.

Both editors support mobile-responsive design and basic personalization. Mailchimp has a slight edge on creative control. Brevo has a slight edge on speed to send because there is less to configure.

This is the section that matters most for small teams evaluating these platforms. Brevo includes marketing automation earlier and more cheaply. Its Free plan supports automation for up to 2,000 contacts, and Standard removes that automation contact limit entirely while adding A/B testing and AI send-time optimization.

Mailchimp's current plan comparison is more nuanced than it used to be. Essentials now includes lighter marketing automation flows, but the plan comparison page caps those at up to 4 steps. Standard is where Mailchimp opens up its fuller 200-step automation flows and optimization tooling.

For a small business watching costs, this is a major differentiator. Automation is not a nice-to-have. It is what lets a one-person operation scale their follow-up beyond what they can do manually. Brevo gives more usable automation earlier in the pricing ladder, while Mailchimp makes more sense if you are paying for its template polish and are comfortable moving into Standard as your workflow matures.

Deliverability is hard to compare objectively without controlled tests on the same domains, lists, and sending habits. The better way to compare these two is through infrastructure options and pricing rather than broad claims about who lands in inboxes more often.

Brevo only offers a dedicated IP as an add-on on Professional and Enterprise. That means a small sender on Brevo's lower tiers is still on shared infrastructure, just like most Mailchimp users.

For the typical small business sender, the real difference is not a published deliverability edge. It is whether you want one platform that can eventually grow into transactional email, SMS, and CRM use cases without changing stacks.

Brevo includes a built-in CRM, called the Sales Platform, on all plans including free. You get a deal pipeline, contact records with activity history, task management, and notes. It is not as deep as a dedicated CRM like monday.com or Pipedrive, but for a solo agency that needs basic pipeline tracking alongside email marketing, it removes the need for a separate tool.

Mailchimp has audience management with tags, segments, and basic contact profiles. It is designed for marketing segmentation, not sales pipeline tracking. There is no deal pipeline, no task management, and limited contact activity history. If you need to track prospects through a sales process, Mailchimp expects you to use a separate CRM.

For small agencies that want fewer tools, Brevo's CRM inclusion is valuable. It will not replace a full CRM for teams with complex sales processes, but it covers the basics. See our Best CRM for Solo Agencies guide for when you need something more robust.

Brevo handles transactional email natively. Password resets, order confirmations, booking notifications, and other triggered messages can sit in the same platform as your marketing campaigns. Prepaid email credits are available on all Brevo plans and can be used for both marketing and transactional emails.

Mailchimp does not include transactional email inside its base marketing plans. You need Mailchimp Transactional, an add-on available for Standard, Premium, and legacy plans. Pricing starts at $20 per block for 25,000 emails, and new users can test up to 500 transactional emails for free.

If you run a service business that sends booking confirmations, invoice notifications, or any event-triggered emails, Brevo's integrated approach saves money and keeps everything in one dashboard. If you only send marketing campaigns and never need transactional messages, this difference does not matter.

Brevo supports SMS more broadly than Mailchimp. Prepaid SMS credits are available on all Brevo plans, while WhatsApp credits are reserved for Professional and Enterprise. Professional also adds WhatsApp campaigns and transactional messaging.

Mailchimp SMS is now available as an add-on to paid plans in select countries, not just one or two markets, but it still requires a separate approval and credit flow. MMS is only available on Standard and Premium for US and Canada programs. WhatsApp is not supported.

Multi-channel outreach is increasingly important for small service businesses. A prospect who does not open an email might respond to an SMS. Brevo gives you a cleaner path if you expect email, SMS, and eventually WhatsApp to live in the same platform. Mailchimp can do some of this, but with more plan and add-on complexity. For teams building lean outreach stacks, this matters. See our guide on Cold Email Stack for Small Service Teams for more on multi-channel setups.

Choose Brevo if you are budget-conscious, need automation early, want basic CRM included, send transactional email, or plan to use SMS and WhatsApp. Brevo's pricing model rewards sending discipline over list size, and its bundled features reduce the number of tools you need to manage.

Choose Mailchimp if you need an extensive template library, are already invested in the Mailchimp ecosystem with integrations, or prioritize visual design polish and ease of use. Mailchimp's editor is best-in-class for teams that care about campaign aesthetics, and its integration catalog is broader.

For solo agencies and small businesses watching costs, Brevo wins on value. You get automation, CRM, transactional email, and multi-channel messaging at a price point that Mailchimp cannot match. The trade-off is a simpler email builder and fewer templates.

Mailchimp wins on polish and ecosystem. Its editor is more refined, its template library is larger, and its integration catalog covers more third-party tools. The trade-off is higher pricing that scales with your contact list, and deeper automation and optimization features sitting further up the pricing ladder.

Neither choice is wrong. But if you are starting fresh, have a limited budget, and want to consolidate tools rather than add them, Brevo is the stronger fit for most small service teams in 2026.
