Choosing an email marketing platform is not just a software decision; it shapes how you build customer relationships, automate campaigns, track revenue, and grow your audience. Sendinblue, now officially known as Brevo, and Mailchimp are two of the most recognizable names in email marketing, but they approach the job in very different ways. One is often praised for affordable scaling and multichannel communication, while the other is known for polished design tools, strong brand recognition, and beginner-friendly campaign creation.
TLDR: Sendinblue/Brevo is generally the better choice if you want unlimited contacts, affordable email volume pricing, SMS marketing, transactional email, and built-in CRM features. Mailchimp is a strong option for small businesses that value an intuitive interface, attractive templates, and broad integrations. If your list is growing quickly, Sendinblue/Brevo may be more cost-effective; if you want a familiar all-in-one marketing platform with excellent usability, Mailchimp remains a compelling choice.
Platform Overview
Sendinblue began as an email marketing and transactional email service, then expanded into SMS, CRM, live chat, marketing automation, landing pages, and sales pipeline tools. In 2023, the company rebranded as Brevo, but many users still refer to it by its original name. Its core appeal is simple: it lets businesses store unlimited contacts on many plans and charges mainly based on how many emails they send.
Mailchimp, meanwhile, became famous for making email marketing feel accessible and even fun. It offers drag-and-drop campaign building, polished templates, audience segmentation, automation, surveys, landing pages, reporting, and ecommerce integrations. Over time, it has evolved from a newsletter tool into a broader marketing platform aimed at small and mid-sized businesses.
The question is not which platform is universally “best.” The better question is: which platform fits your marketing style, budget, team size, and growth plans?
Ease of Use
Mailchimp has long been appreciated for its clean, friendly interface. Its campaign builder is straightforward, and beginners can create professional-looking emails without much training. The platform guides users through list setup, template selection, subject lines, previews, and scheduling in a logical flow. If you are completely new to email marketing, Mailchimp’s onboarding experience is one of its biggest advantages.
Sendinblue/Brevo is also approachable, though its interface can feel more businesslike than playful. It includes more operational tools, such as sales pipelines, transactional emails, chat widgets, and SMS campaigns, so the dashboard may initially feel broader. However, once users understand where things live, campaign creation is simple and efficient.
Winner for ease of use: Mailchimp, especially for beginners who prioritize a smooth design experience.
Email Design and Templates
Both platforms offer drag-and-drop editors, reusable blocks, responsive templates, personalization options, and preview tools. For most newsletters, product announcements, welcome emails, and promotional campaigns, either platform can produce attractive results.
Mailchimp tends to have a stronger reputation for design polish. Its templates are modern, varied, and easy to customize. The editing experience is intuitive, making it simple to adjust images, buttons, columns, colors, and text blocks. For brands that care heavily about visual presentation, Mailchimp feels refined.
Sendinblue/Brevo provides a solid email editor with useful templates, but the template library may feel less extensive or less stylistically distinctive than Mailchimp’s. That said, it offers everything most businesses need: responsive layouts, dynamic personalization, brand styling, and saved templates.
Winner for design: Mailchimp, though Sendinblue/Brevo is more than capable for standard campaigns.
Pricing and Value
Pricing is where the comparison becomes especially interesting. Mailchimp typically bases pricing on contact count and feature level. As your audience grows, your monthly cost can rise significantly, even if you do not email every subscriber frequently. This makes list hygiene important: inactive, unsubscribed, or unnecessary contacts can affect cost if they remain in your audience structure.
Sendinblue/Brevo takes a different approach. Many plans allow unlimited contacts, and pricing is primarily based on email volume. This is a major advantage for businesses with large databases that send campaigns selectively. For example, if you have 80,000 contacts but only email certain segments each week, Sendinblue/Brevo can be much more economical.
However, the cheapest option is not always the best. Mailchimp’s higher-priced plans may include more advanced testing, segmentation, and optimization features. Sendinblue/Brevo’s value shines most when contact volume is high, transactional email is important, or you need SMS and CRM features in the same ecosystem.
- Choose Sendinblue/Brevo if: you have many contacts and want predictable email-volume-based pricing.
- Choose Mailchimp if: you have a smaller list and value a polished interface with strong template tools.
Automation Capabilities
Automation is one of the most important features in modern email marketing. Welcome sequences, abandoned cart reminders, lead nurturing flows, birthday emails, re-engagement campaigns, and behavior-based triggers can save time while increasing revenue.
Mailchimp offers customer journeys that allow marketers to build automated paths based on user actions, tags, purchases, or engagement. It is especially useful for ecommerce stores, content creators, and small businesses that want prebuilt automation ideas. The visual journey builder is easy to understand and helps teams map out customer communication.
Sendinblue/Brevo also includes strong automation tools, including workflows based on email engagement, website behavior, contact attributes, transactional events, and CRM activity. It is particularly useful for businesses that combine email marketing with sales follow-up, SMS notifications, or transactional messages. For more technical teams, Brevo can feel flexible and practical.
Winner for automation: It depends. Mailchimp is easier for simple customer journeys, while Sendinblue/Brevo is strong for multichannel and transactional workflows.
Contact Management and Segmentation
Good email marketing depends on sending relevant messages to the right people. Both tools support segmentation, tags, custom fields, and audience filters, but they differ in how flexible and affordable those features feel at scale.
Mailchimp provides powerful audience tools, including tags, groups, segments, predictive insights on some plans, and behavioral data from integrations. However, its audience structure can sometimes be confusing for users managing multiple lists or overlapping customer groups. Duplicate contacts across audiences may create billing complications, so organization matters.
Sendinblue/Brevo uses lists, segments, and contact attributes in a way that often feels more straightforward for large databases. Since many plans allow unlimited contacts, businesses can focus more on organizing and targeting their audience and less on whether every stored contact is increasing the bill.
Winner for contact management: Sendinblue/Brevo for large or complex contact databases; Mailchimp for smaller lists and simpler audience structures.
Transactional Email and SMS Marketing
This is one of Sendinblue/Brevo’s clearest strengths. The platform includes transactional email capabilities for order confirmations, password resets, shipping updates, receipts, and other essential messages. It also supports SMS marketing, allowing businesses to reach customers through another high-visibility channel.
Mailchimp does offer transactional email through Mailchimp Transactional, formerly Mandrill, but it is more separate from the core email marketing experience and may require additional setup or cost considerations. Mailchimp also has SMS features in certain regions and plans, but Brevo’s multichannel communication has historically been a central part of its platform.
If your business needs both marketing emails and operational messages, Sendinblue/Brevo may feel more unified.
Reporting and Analytics
Both platforms provide essential metrics such as open rates, click rates, bounce rates, unsubscribes, device data, geographic performance, and campaign comparisons. These insights help marketers understand what is working and what needs improvement.
Mailchimp presents reports in a visually appealing and digestible way. It is easy to see campaign performance, ecommerce revenue, audience growth, and engagement trends. For teams that want quick insights without digging too deeply, Mailchimp’s reports are user-friendly.
Sendinblue/Brevo provides practical analytics with campaign stats, automation tracking, deliverability metrics, heat maps, and transactional email performance. It may feel a little less polished visually, but it gives businesses the data they need to optimize campaigns.
Winner for reporting: Mailchimp for presentation and readability; Sendinblue/Brevo for operational and transactional tracking.
Ecommerce Features
For online stores, Mailchimp has a strong reputation thanks to integrations with platforms such as Shopify, WooCommerce, BigCommerce, and others. It supports abandoned cart emails, product recommendations, purchase-based segmentation, promo codes, and revenue reporting. These features make it attractive for small ecommerce brands that want email marketing tied closely to sales activity.
Sendinblue/Brevo also supports ecommerce workflows, including abandoned cart campaigns, transactional messages, segmentation based on purchases, and integrations with popular store platforms. It can be especially appealing if you want email, SMS, and transactional communication in one place.
Winner for ecommerce: Mailchimp for plug-and-play ecommerce marketing; Sendinblue/Brevo for stores that also need SMS and transactional communication.
Deliverability
Email deliverability depends on many factors: sender reputation, list quality, authentication, content, engagement, and sending behavior. Both Sendinblue/Brevo and Mailchimp are established providers with the infrastructure needed to deliver campaigns reliably.
Mailchimp offers strong deliverability guidance, domain authentication tools, and compliance features. It is widely used, which means many marketers trust its sending infrastructure. Sendinblue/Brevo also offers deliverability tools, dedicated IP options, and transactional email systems designed for reliable sending.
The real difference often comes down to how you manage your list. A clean list with engaged subscribers will usually perform better than a purchased or neglected list, regardless of the platform.
Customer Support
Support quality can vary depending on your plan. Mailchimp offers a large knowledge base, tutorials, email support, and chat support on paid plans, with priority support available at higher tiers. Its documentation is thorough and beginner-friendly.
Sendinblue/Brevo also provides help documentation, email support, and plan-based support options. Users who rely on CRM, SMS, or transactional email may appreciate having several communication tools supported within one system.
If support is critical to your business, compare the exact support options included in the plan you are considering, not just the platform overall.
