Brevo vs. Mailchimp: The Definitive 2026 Showdown

For over a decade, Mailchimp was the default answer when someone asked, "What email tool should I use?" But massive price hikes and feature restrictions have left many small business owners looking for alternatives.

Enter Brevo (formerly Sendinblue). It has positioned itself as the budget-friendly, feature-rich alternative. But is it actually better?

The Core Difference: Pricing Models

This is the dealbreaker for most people.

• Mailchimp charges by Contacts. If you have 5,000 subscribers but only email them once, you pay for all 5,000.
• Brevo charges by Emails Sent. You can have unlimited contacts. You only pay for what you use.

Comparison at a Glance

Transactional Emails	Paid Add-on (Mandrill)	Included

Automation: Who Wins?

Mailchimp's "Customer Journey Builder" is good, but it's restricted on lower tiers. You often have to pay for the Standard plan to get multi-step automations.

Brevo gives you full automation on the Free plan. You can build complex, multi-path workflows based on behavior, scores, and attributes without paying a dime. For bootstrapped startups, this is a game-changer.

Ease of Use

This is one area where Mailchimp still has an edge. Their interface is incredibly polished, friendly, and intuitive. "The Chimp" guides you through everything.

Brevo is more utilitarian. It feels like a software tool. It's powerful, but it might take you an afternoon to learn where everything is hidden. However, once you learn it, it's just as fast.

Conclusion: Which One Should You Choose?

Choose Mailchimp if: You have a large budget, you value a cute/easy interface above all else, and you need specific integrations that only Mailchimp has (though Brevo has most).

Choose Brevo if: You want to save literally hundreds of dollars a year, you need advanced automation, or you want to combine Email and SMS.

For 95% of the small businesses we consult with, the math is simple: Brevo is the smarter financial choice.
