Brevo vs Mailchimp for Small Business: Which Should You Actually Pay For in 2026?

For most small businesses, Brevo is the better value — it charges by emails sent rather than contacts, and its free plan is far more generous than Mailchimp’s. Mailchimp is the better pick if you want a large template library, deep e-commerce integrations, and the name everyone recognizes — but its free plan is small and its paid prices climb fast as your list grows. The honest answer: pick Brevo if keeping costs down as you grow matters most, pick Mailchimp if polish and integrations matter more. Check both tools’ current pricing pages before you pay, since plans and limits change.

That is the short version. Below is the full side-by-side, with the pricing models, the free-plan details that decide your early bill, and the billing detail Mailchimp uses that most comparisons skip. Prices and limits change often, so treat anything quoted here as a guide and confirm the current figures on each tool’s official pricing page before you commit.

What Is the Real Difference Between Brevo and Mailchimp?

Think of it this way: Brevo charges you for what you send. Mailchimp charges you for who is on your list.

Brevo (formerly Sendinblue) was built around sending email cheaply. Its pricing is based on how many emails you send per month, not how many contacts you store. That single difference changes the entire math for a small business with a growing list.

Mailchimp is the giant of the email world — the name every small business owner has heard. It charges per contact, with generous-looking tiers that get expensive the moment your list grows. It also has polished templates, a wide range of integrations, and a large tutorial library.

So the question is not really “which is better.” It is “do you want cheaper sending, or a more polished platform?”

How Much Do Brevo and Mailchimp Cost in 2026?

Let us start with money, because pricing is where these two tools are the most different. Prices are approximate as of 2026 and change — always check the official pricing pages before you pay.

Brevo pricing

• Free: $0. No cap on contacts on the free plan, with a daily sending limit — check the current limit on Brevo’s pricing page. You read that right — there is no subscriber cap on the free plan. The limit is on daily sending.
• Starter: a low monthly starting price (check the current figure on Brevo’s pricing page). More monthly sends, no daily cap, no Brevo logo on your emails.
• Business: a mid-tier monthly price (check the current figure on Brevo’s pricing page). Adds marketing automation, A/B testing, and more.
• Enterprise: custom pricing. For large teams with dedicated support.

The key detail: you pay for email volume, not list size. A business with 10,000 contacts that sends two campaigns a month pays far less on Brevo than on Mailchimp.

Mailchimp pricing

• Free: $0. A small contact limit and a monthly send allowance — check the current limits on Mailchimp’s pricing page, since the free plan has been cut back over time. It works as a trial, not something you can run a growing business on.
• Essentials: a low monthly starting price for a small contact allowance (check the current figure on Mailchimp’s pricing page). Single-step automation, A/B testing, 24/7 support.
• Standard: a higher monthly starting price for the same starting contact allowance (check the current figure on Mailchimp’s pricing page). Multi-step automations, send-time optimization, generative AI features, predictive segmentation.
• Premium: a much higher monthly price aimed at larger lists (check the current figure on Mailchimp’s pricing page). Advanced segmentation, comparative reporting, phone support.

The billing detail most comparisons skip

Here is the part that decides your bill: Mailchimp’s billing has counted unsubscribed contacts toward plan limits. An old unsubscribed contact can still count unless you manually archive it — confirm the current billing rules on Mailchimp’s pricing page, since billing rules can change. Your list stays flat; your bill keeps climbing.

Brevo’s model does not charge by list size. On the free plan you pay nothing until your sending passes the daily cap, no matter how many contacts you store.

So the headline starting prices are not the whole story. A small business with a large list sending the same two campaigns a month either way can pay considerably less on Brevo, because Brevo bills on sends, not contacts.

Which Has the Better Free Plan?

Brevo wins this round, and it is not close.

Brevo’s free plan gives you unlimited contacts with a daily sending cap (check the current cap on Brevo’s pricing page). You can run a real small business newsletter on it for months — maybe a year — before paying anything. The limits are real (daily sending cap, Brevo branding on emails), but they are workable.

Mailchimp’s free plan gives you a small contact limit and a monthly send allowance (check the current limits on Mailchimp’s pricing page). That is enough to test the platform, not to run a business. The moment your list passes the small free-plan limit — which happens fast if you are growing — you are paying.

If you are starting from zero and want to grow before spending money, Brevo is the obvious choice.

Which Is Better for Email Automations?

Brevo wins for affordability. Mailchimp wins for depth — on the higher plans.

Brevo includes marketing automation from its Business plan (check the current price on Brevo’s pricing page), and the automation builder covers the essentials well: welcome sequences, abandoned cart flows, birthday emails, lead scoring.

Mailchimp gates automation harder. The Essentials plan only allows single-step automations. Real multi-step customer journeys — welcome series, win-back flows, post-purchase sequences — need the Standard plan (check the current price on Mailchimp’s pricing page). On Standard, though, the automation builder is genuinely excellent, with predictive segmentation and AI-assisted timing that Brevo does not match. New to the platform? Here is how to use Mailchimp for email marketing.

For a small business that needs solid basics without paying for a higher-tier plan, Brevo. For one that wants the smartest automation engine and is willing to pay for Standard, Mailchimp.

Which Has Better Email Templates?

Mailchimp wins here, clearly. Its template library is bigger and easier to customize with drag-and-drop. If you want beautiful, branded, image-heavy emails fast, Mailchimp makes it happen.

Brevo’s templates are fine — clean, professional, serviceable. But the library is smaller and the designs feel more “business software” than “design studio.” If visual polish is central to your brand, you will feel the difference.

That said, here is an honest counterpoint: simple emails often perform better. Plain, personal-looking emails tend to get more opens and replies than heavily designed ones. If your emails look like they came from a person rather than a marketing department, Brevo’s simpler templates are not a disadvantage. If you need inspiration, these email newsletter ideas for small business owners show how simple formats can carry a newsletter.

Which Is Better for E-Commerce?

Mailchimp wins for online stores. It has deep e-commerce integrations — a built-in Shopify integration, abandoned-cart reminders, personalized product recommendations, and post-purchase flows. If you run a store, Mailchimp’s selling features are stronger out of the box. See our guide to email marketing for ecommerce stores for the full playbook.

Brevo handles e-commerce competently — it has transactional emails, SMS marketing, and a built-in CRM — but it does not have Mailchimp’s depth of store-specific features. The SMS marketing is a genuine plus that Mailchimp charges more for, though.

So: selling physical products through Shopify? Mailchimp. Sending campaigns and SMS on a budget? Brevo.

Which Is Easier to Use?

Both are beginner-friendly, but in different ways.

Brevo is simpler. Fewer features, cleaner pricing, less to learn. You can set up your account and send your first campaign in an afternoon. The trade-off is that some advanced features feel less polished than Mailchimp’s.

Mailchimp has more going on. More features, more menus, more settings. It takes a bit longer to learn, and some of it feels like clutter if you only need basic email. But you get more tools once you are comfortable.

How Do They Compare as Your List Grows?

This is where Brevo’s pricing model really shines for small businesses.

On Brevo, growing your list barely changes your bill — you only pay more when you send more emails. A list that doubles from 2,500 to 5,000 costs you nothing extra if your sending volume stays the same.

On Mailchimp, every contact tier jump raises your bill. At a few thousand contacts, the Essentials and Standard plans cost several times their starting prices — check the current tier pricing on Mailchimp’s pricing page. That is a real monthly cost for a small business — for contacts, not even for sending. Keeping your list healthy helps: segment your email list and clean your email list regularly so you are not paying for contacts who never engage.

The honest math: if your list is growing steadily, Brevo stays cheap. Mailchimp gets expensive in proportion to your success, which is an odd thing to pay for.

So Which Should You Pick?

Here is the short version:

Pick Brevo if:

• You want the most generous free plan (unlimited contacts, daily sending cap)
• Your list is growing and you do not want the bill to grow with it
• You send a few campaigns a month, not daily blasts
• You want SMS marketing and a CRM included at a fair price
• Your budget is tight — paid plans at a low starting price (check the current pricing page)

Pick Mailchimp if:

• You want the best-looking templates and easiest design experience
• You run an online store (Shopify integration, abandoned carts, product recommendations)
• You want strong automation features and are willing to pay for Standard
• You value a large tutorial library and community support
• Your list is small and you will keep it clean by archiving unsubscribes

Our honest take: for most small businesses, Brevo is the smarter buy. The free plan alone removes the pressure to pay before you are ready, and the send-based pricing means your bill does not punish you for growing. Mailchimp is the better choice when your business looks more like a store than a newsletter — and when the template quality and e-commerce depth are worth the higher, contact-based price. If neither feels right, compare these Mailchimp alternatives for small business.

Frequently Asked Questions

Is Brevo really free for unlimited contacts?

Yes. Brevo’s free plan has no subscriber cap — you can store as many contacts as you like. The limit is on sending: a daily cap (check the current figure on Brevo’s pricing page). You also get Brevo branding on your emails until you upgrade. Paid plans start at a low monthly price — check the current pricing page.

Why is Mailchimp’s free plan so limited now?

Mailchimp has cut its free plan back over time to a small contact limit and a monthly send allowance — check the current limits on Mailchimp’s pricing page. It is positioned as a trial now. If you need a real free plan for a growing list, Brevo’s free tier is far more generous.

Does Mailchimp really charge for unsubscribed contacts?

Mailchimp’s billing has counted subscribed, unsubscribed, and non-subscribed contacts toward plan limits — confirm the current rules on Mailchimp’s pricing page. Only archived, cleaned, or pending contacts have been excluded. Archive your unsubscribes regularly or you may pay for contacts who never read your emails.

Can I switch from Mailchimp to Brevo easily?

Yes. Every major email tool lets you export your subscriber list as a CSV and import it elsewhere. The annoying part is rebuilding your automations and templates by hand. Plan for an afternoon of cleanup after the move.

Which is better for a startup on a tight budget?

Brevo, in most cases. The free plan (unlimited contacts, daily sending cap) covers the early months, and paid plans at a low starting price stay cheap as your list grows. Mailchimp’s contact-based pricing starts looking expensive the moment your list passes a few thousand people.

The Bottom Line

Brevo vs Mailchimp for small business is not really a fight — it is a fork in the road. Choose Brevo if you want your email costs to stay low while your list grows. The unlimited-contacts free plan, the send-based pricing, and the low starting price make it the budget-friendly choice for almost every small business. Choose Mailchimp if you want polished templates, deep e-commerce features, and the most recognized brand name — and you are willing to pay contact-based prices for it. Either way, verify the current prices on the official sites before you commit, and start on the free plan that fits, not the paid plan that impresses.
