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 advanced features like automation and A/B testing sit behind higher tiers. Brevo has moved in the opposite direction, bundling CRM, transactional email, SMS, and WhatsApp into a single platform at a lower 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 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.

Brevo Starter begins at $9 per month for 5,000 emails with unlimited contacts. Mailchimp Essentials starts at $13 per month for 500 contacts. As your list grows, the gap widens. At 2,500 contacts, Mailchimp Essentials jumps to around $39 per month. Brevo Starter stays at $9 per month as long as your send volume stays under 5,000 emails.

Brevo Business starts at $18 per month for 5,000 emails, adding A/B testing, advanced statistics, and multi-user access. Mailchimp Standard starts at $20 per month for 500 contacts, and that is where you finally get automation and send-time optimization. For a small agency with a growing list and limited budget, Brevo's volume-based model is meaningfully cheaper.

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 automation on its free plan. You can build multi-step workflows triggered by sign-ups, page visits, email opens, or custom events without paying anything. That means a solo agency can set up a welcome sequence, a lead nurture flow, and a re-engagement campaign at zero cost.

Mailchimp gates automation behind its Standard plan, which starts at $20 per month for 500 contacts. The free and Essentials plans only support single-step automations like a basic welcome email. If you want branching logic, A/B paths in automations, or multi-step sequences, you need Standard or higher.

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 giving it away on the free tier is a meaningful advantage. For a deeper look at running a full automation setup on Brevo, see Brevo for Solo Agencies: Full Funnel Guide.

Both Brevo and Mailchimp have solid deliverability reputations. Mailchimp uses its Omnivore abuse detection system to proactively flag risky lists and content, which helps maintain shared IP reputation across its user base. For most small senders on shared infrastructure, Mailchimp delivers reliably.

Brevo offers a dedicated IP option starting on its Business plan at $18 per month. A dedicated IP gives you full control over your sender reputation, which matters if you send high volumes or mix marketing and transactional email. For smaller senders, Brevo's shared IP pools perform well.

Neither platform is meaningfully better at inbox placement for the typical small business sender. Both enforce list hygiene, authentication (SPF, DKIM, DMARC), and provide deliverability reporting. The difference is at the edges: if you want dedicated infrastructure at a lower price point, Brevo offers that earlier in its plan lineup.

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 run on the same platform as your marketing campaigns. The free plan includes transactional email within the 300 emails per day limit, and paid plans offer dedicated transactional capacity.

Mailchimp does not include transactional email in its core product. You need Mandrill, a separate add-on that starts at $20 per month as a block of credits, on top of your existing Mailchimp subscription. For a small business that sends both marketing and transactional email, this adds cost and complexity.

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 includes SMS and WhatsApp marketing as built-in channels. You can send SMS campaigns, add SMS steps to automation workflows, and use WhatsApp Business messages for customer communication. SMS pricing is pay-as-you-go on top of your plan, but the infrastructure is there from the start.

Mailchimp added SMS support in 2023, but it remains limited to US and UK numbers and is only available on Standard and Premium plans. WhatsApp is not supported at all. For agencies serving local markets where text follow-ups convert well, Brevo's multi-channel options provide more flexibility.

Multi-channel outreach is increasingly important for small service businesses. A prospect who does not open an email might respond to an SMS. Brevo lets you build those sequences in one tool. With Mailchimp, you would need a separate SMS provider and an integration layer. 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 key features like automation locked behind more expensive tiers.

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.
