There isn't one "best" email marketing platform here — there's a best fit for your list size, your automation ambitions, and how much of your stack you want one tool to cover. Mailchimp, Brevo and ActiveCampaign all do email well, but they're built around different jobs: Mailchimp around familiar, beginner-friendly campaign sending; Brevo around a broad, value-priced multichannel toolkit; and ActiveCampaign around deep, flexible marketing automation. This guide compares them side by side so you can pick by use case rather than by brand recognition.
TL;DR by buyer
- Pick Mailchimp if you're a small team or creator who wants a familiar builder, templates and a huge ecosystem of integrations, and your automations will stay fairly simple.
- Pick Brevo if you want one platform to cover email, SMS/WhatsApp, transactional messaging and a lightweight CRM without paying enterprise prices, and you're comfortable with a slightly more setup-heavy start.
- Pick ActiveCampaign if automation depth is the priority — multi-step, behaviour-triggered workflows, lead scoring and CRM pipelines — and you're an SME, mid-market team or agency that can invest a bit more time in building it right.
None of the three is a universal winner. The right pick depends on whether you're optimising for simplicity, breadth, or automation power.

Email creation
Mailchimp has the most familiar drag-and-drop email builder of the three, with a large template library, audience management and landing pages — the reason it remains a common default for small teams and creators sending straightforward newsletters and ecommerce messaging.
Brevo's email builder covers standard campaign needs plus transactional email through the same account, which is useful if you want marketing and transactional sends (like order confirmations) managed in one place rather than split across two tools.
ActiveCampaign's email builder is capable but is really the entry point into its automation engine — campaigns, forms and segmentation all feed into the same workflow builder, so email creation here is less about standalone newsletters and more about triggering the next step in a journey.
Round winner: Mailchimp, for pure ease of building and sending a one-off campaign without a learning curve.
Automation
This is where the three separate the most clearly.
ActiveCampaign is built around visual, multi-step automations — behaviour triggers, conditional branching, lead scoring and predictive/AI-assisted sends — and is designed for teams that want to build genuinely personalised, multi-touch journeys without buying an enterprise suite.
Brevo offers solid marketing automation for standard use cases (welcome series, abandoned-cart flows, re-engagement) but its automation and reporting are described as less deep than enterprise-grade tools, with limits varying by plan tier.
Mailchimp covers basic automations — journeys, triggered sends — well enough for straightforward use cases, but its automation depth trails specialist platforms once workflows get complex.
Round winner: ActiveCampaign.
CRM / segmentation
ActiveCampaign pairs its automation engine with CRM pipelines, making it a strong fit for teams that want marketing and light sales pipeline management in one place — particularly SMEs and agencies that don't need a full enterprise CRM.
Brevo includes a lightweight CRM, useful for keeping contact and deal context alongside campaigns, but it's positioned as a supporting feature rather than the product's core strength.
Mailchimp's segmentation is capable for audience management (tags, groups, predicted demographics) but it doesn't offer the same pipeline-style CRM depth as the other two.
Round winner: ActiveCampaign, for teams that want automation and lightweight CRM working together.
Multichannel
Brevo is the clearest multichannel play of the three: email, SMS/WhatsApp, transactional API and forms sit under one roof, which matters if you want to consolidate vendors rather than bolt on a separate SMS tool.
Mailchimp and ActiveCampaign are both primarily email-first platforms with automation extending into other touchpoints (landing pages, forms, and in ActiveCampaign's case, CRM-driven outreach), but neither matches Brevo's native SMS/WhatsApp breadth out of the box.
Round winner: Brevo.
Analytics
None of the three publish independently benchmarked performance data for deliverability or reporting accuracy, so treat vendor-reported analytics as directional rather than audited.
- Mailchimp and Brevo both offer standard campaign-level reporting (opens, clicks, revenue attribution for ecommerce sends).
- ActiveCampaign extends this with automation-level reporting and CRM pipeline reporting, which is useful once you're running multi-step journeys and want to see where contacts drop off.
Round winner: ActiveCampaign, for teams running automations who need workflow-level visibility, not just campaign-level opens and clicks.
Integrations
- Mailchimp has the broadest small-business ecosystem — Shopify, WooCommerce, social platforms and a long tail of app-store integrations — which suits solo operators and small ecommerce teams already living in that ecosystem.
- Brevo covers ecommerce, CRM and CMS integrations plus Zapier/Make and developer APIs for anything not natively supported.
- ActiveCampaign lists integrations in the hundreds, spanning ecommerce, CRM, forms and automation tools — a strength for teams that need their automation platform to sit at the centre of a wider martech stack.
Round winner: Tie between Mailchimp (best for SMB/ecommerce app-store breadth) and ActiveCampaign (best for automation-centric stacks).
Pricing at different list sizes
All three price primarily on contact/list size, with plan tier layered on top:
- Mailchimp offers a free tier plus paid, contact-based tiers; pricing is reported to escalate as your audience grows, so a plan that looks affordable at a few hundred contacts can get materially more expensive as you scale.
- Brevo offers a free plan and paid tiers that are generally based on send volume and feature access rather than contact count alone — worth checking closely if your list is large but your sending frequency is low, since that can work in Brevo's favour.
- ActiveCampaign uses tiered subscriptions based on contacts and feature tier, with a free trial (no permanent free plan); get a list-size-specific quote before committing, since published starting prices rarely reflect the cost at scale.
We have not verified current dollar figures, plan limits or list-size breakpoints for this comparison — vendor pricing changes periodically and none of our canonical research records include a recent price-verification date for these three tools. Before this page is published, confirm current pricing directly on each vendor's pricing page and add a "pricing as of [month, year]" note, per house style for pricing content. Do not publish the page with unverified pricing claims.
What we can say directionally: Brevo is generally positioned as the most accessible option for value-conscious SMEs; Mailchimp's costs are more likely to rise quickly with list growth; ActiveCampaign's total cost depends heavily on the automation/CRM tier you need, not just contact count.
Best by use case
- Solo creators and very small teams sending simple newsletters: Mailchimp. The builder and template library reduce time-to-send, and the free plan is a low-risk way to start.
- SMEs that want email, SMS/WhatsApp and transactional messaging without three separate vendors: Brevo. Its multichannel breadth at accessible pricing is the clearest differentiator.
- Ecommerce teams already on Shopify or WooCommerce: Mailchimp, for the depth of native ecommerce integrations and revenue-attribution reporting.
- Agencies and B2B teams running multi-step, behaviour-triggered campaigns: ActiveCampaign. The automation builder and CRM pipelines are the strongest of the three for this job.
- Mid-market teams that need automation depth but aren't ready for an enterprise suite (e.g. HubSpot, Adobe Marketo, Salesforce Marketing Cloud): ActiveCampaign is the natural step-up.
Final recommendation
If you had to choose in under a minute: start with Mailchimp if your needs are simple and you value familiarity; choose Brevo if channel breadth (email + SMS/WhatsApp + transactional) matters more to you than automation depth; choose ActiveCampaign if automation and lightweight CRM are the actual job you're hiring the tool to do.

FAQs
Is Mailchimp, Brevo or ActiveCampaign better for beginners? Mailchimp is generally the easiest to start with for simple newsletters, thanks to its familiar builder and large template library. Brevo is also approachable but needs a bit more setup to make full use of its multichannel features. ActiveCampaign has the steepest learning curve of the three because its email tools are built around a broader automation engine.
Which is cheapest for a small list? All three offer a free or low-cost entry point (Mailchimp and Brevo have free plans; ActiveCampaign offers a free trial only). At small list sizes the gap between them is usually modest — the bigger cost differences show up as your list and automation needs grow. Confirm current pricing directly with each vendor before deciding, since we have not verified up-to-date figures for this comparison.
Which has the best automation? ActiveCampaign, by a clear margin among these three. Its visual automation builder, behaviour triggers, lead scoring and CRM pipelines are built for multi-step, personalised journeys in a way Mailchimp and Brevo's automation tools don't fully match.
Can I use more than one of these together? It's uncommon and usually unnecessary — most teams standardise on one platform to avoid duplicate contact lists and inconsistent reporting. A more common pattern is starting on Mailchimp or Brevo and migrating to ActiveCampaign (or a heavier platform) once automation needs outgrow the starting tool.
What should make me switch away from my current platform? Typical triggers are: automation workflows becoming too limited or expensive on your current plan, needing SMS/WhatsApp alongside email (a reason to consider Brevo), needing CRM pipeline functionality your current tool lacks (a reason to consider ActiveCampaign), or costs escalating faster than your list justifies (worth comparing Mailchimp's contact-based pricing against the alternatives).
Are there good alternatives if none of these three fit? Yes — Klaviyo and Constant Contact both come up as alternatives to this group, particularly for ecommerce-heavy sends (Klaviyo) or organisations wanting a long-established, support-heavy vendor (Constant Contact).
