Brevo vs Mailchimp: Which Is Cheaper Per Contact?

If you're comparing Brevo vs Mailchimp, you're likely weighing cost against reliability. You want to send emails without overpaying — especially when your list grows. As of May 2026, Brevo (formerly Sendinblue) remains one of the few email marketing tools that charges per contact, not per email sent or per active contact tier. Mailchimp, by contrast, now bills based on active contacts — and its pricing jumps sharply at 500, 2,500, and 10,000 contacts.

How Brevo and Mailchimp Actually Charge

This is where most buyers get tripped up. Neither tool uses simple flat-rate plans anymore — but their billing logic differs in ways that directly affect your bottom line.

Brevo counts all contacts stored in your account, regardless of engagement status. You pay once per contact per month — even if they’re unsubscribed or unconfirmed. Its free plan includes 300 contacts and unlimited emails. Paid plans start at $25/month for up to 10,000 contacts — and include SMS, landing pages, and basic CRM features.

Mailchimp counts only active contacts: those who’ve opened or clicked an email in the last 15 months, or were added in the last 30 days. Inactive contacts don’t count toward your plan limit — but they stay in your account and can be reactivated with a single import. Its free plan covers 500 contacts and 1,000 sends/month. The next tier — Essentials — starts at $13/month for up to 500 active contacts, rising to $299/month for 50,000 active contacts.

So which is cheaper? It depends entirely on your list hygiene and sending frequency.

The Real Per-Contact Cost Comparison

Let’s run numbers for three realistic scenarios — using official pricing from Brevo’s pricing page and Mailchimp’s pricing page, both verified as of May 2026.

Scenario 1: 2,000 contacts, low engagement (e.g., a local nonprofit)

• Brevo: $25/month for up to 10,000 contacts — so $0.0125 per contact/month.
• Mailchimp: If only 800 are active (e.g., 40% open rate over 15 months), you qualify for the $20/month plan (up to 2,500 active contacts). That’s $0.025 per active contact — but you’re storing 2,000 total contacts, so the effective cost per stored contact is $0.01.

In this case, Mailchimp edges out Brevo slightly — if your inactive rate stays high and you never need SMS or automation beyond email.

Scenario 2: 7,500 contacts, moderate activity (e.g., SaaS newsletter)

• Brevo: Still $25/month (covers up to 10,000 contacts).
• Mailchimp: With ~60% activity (4,500 active), you’d land in the $99/month tier (covers up to 10,000 active contacts). That’s $0.0132 per active contact — but $0.0132 per active contact means $0.0132 × 4,500 = $59.40 effective cost, while Brevo charges $25 flat. So Brevo saves you $74/year here.

Scenario 3: 15,000 contacts, high churn (e.g., e-commerce brand)

• Brevo: $55/month for up to 25,000 contacts ($0.0037 per contact).
• Mailchimp: Even with 50% activity (7,500 active), you’d need the $199/month plan (covers up to 25,000 active contacts). That’s $0.0265 per active contact — and $0.0133 per total contact. Brevo saves $1,728/year in this scenario.

These calculations assume no add-ons. But real-world usage includes more than just sending emails.

What You Get Beyond Email

Both tools bundle features — but the bundles differ significantly.

Brevo includes (on all paid plans):

• SMS messaging: $0.0075 per outbound SMS in the US (as listed on Brevo’s pricing page)
• CRM with contact scoring and deal pipelines
• Landing pages and forms (no extra fee)
• Transactional email API (unlimited sends on paid plans)
• Basic marketing automation (up to 3 workflows on Starter)

Mailchimp includes (on Essentials and higher):

• Basic audience segmentation and A/B testing
• Customizable signup forms and pop-ups
• Google Ads and Meta integration (requires separate ad accounts)
• No built-in SMS — you must use a third-party app like Twilio via Zapier
• No native CRM: contacts exist only as lists or audiences; no deal tracking or lead scoring

That means if you need SMS or CRM functionality, Brevo avoids $50–$100/month in third-party tools. Mailchimp’s Audience Manager add-on — required for advanced segmentation beyond basic tags — costs an extra $25/month on top of Essentials.

Deliverability & Inbox Placement

Both platforms maintain strong sender reputation. Brevo publishes its own deliverability report, citing 98.2% inbox placement across major ISPs (Gmail, Outlook, Yahoo) for authenticated domains as of Q1 2026. Mailchimp reports similar figures: 97.9% average inbox rate across its customer base, per its 2026 Deliverability Guide.

But setup matters more than averages. Both require domain authentication (SPF, DKIM, DMARC) — and neither auto-configures it. Brevo offers guided setup inside the dashboard; Mailchimp provides step-by-step docs but no in-app wizard. Users on G2 note this difference: “Brevo walked me through DNS setup in under 10 minutes. Mailchimp made me copy-paste records into my registrar — and I got it wrong twice,” wrote a marketing manager from Austin, TX, in a May 2026 G2 review.

Automation & Workflows

Brevo’s visual workflow builder supports entry triggers (e.g., form submission, tag addition), delays, splits (based on attributes or behavior), and actions like email, SMS, or tag updates. On the Starter plan ($25/month), you get 3 active workflows. The Business plan ($65/month) unlocks unlimited workflows and conditional logic.

Mailchimp’s automation is tied to audience activity. You can trigger emails based on opens, clicks, purchases (via e-commerce integrations), or date-based events (e.g., birthdays). But branching logic is limited unless you upgrade to Premium ($299/month), which adds custom conditions and multi-step decision trees.

A Capterra reviewer noted the gap: “I built a 7-step abandoned cart flow in Brevo in 20 minutes. In Mailchimp, I had to use three separate automations and duplicate segments — and it still didn’t handle partial checkouts correctly.” (Capterra Brevo review, April 2026)

Reporting & Analytics

Both show open rates, click-through rates, bounce rates, and device breakdowns. Brevo adds heatmaps for email content (showing where users scroll and click) on all paid plans. Mailchimp offers heatmaps only on the Premium plan — alongside predictive analytics like “likelihood to purchase” scores.

Neither platform offers cohort-based retention reporting out of the box. If you need to track how subscribers from a May 2026 campaign behave over 90 days, you’ll need to export data and analyze it externally — or use a BI tool like Google Looker Studio.

Integrations

Brevo has 150+ native integrations, including Shopify, WordPress, WooCommerce, HubSpot (read-only), and Salesforce (via Brevo’s official connector). Its API is RESTful and well-documented, with SDKs for PHP, Python, Node.js, and Ruby.

Mailchimp supports 300+ integrations — but many are via Zapier or Make, not native. Its direct Salesforce sync is bidirectional and robust, while Brevo’s is one-way (contacts only). For WordPress users, Brevo’s official plugin handles form sync and contact tagging automatically; Mailchimp’s plugin requires manual field mapping for anything beyond email capture.

User Experience & Learning Curve

Brevo’s interface is clean and task-oriented. The left-hand navigation groups features by function (Email, SMS, CRM, Automation), and tooltips explain each setting. Its drag-and-drop email builder uses a block-based layout — similar to Mailchimp’s — but allows more granular control over padding, fonts, and background images without code.

Mailchimp’s interface has grown more complex since its 2023 redesign. Tabs like “Campaigns”, “Audience”, “Templates”, and “Reports” sit at the top, and submenus expand unpredictably. Several reviewers on G2 cite confusion around list vs. audience management: “I accidentally deleted a segment thinking it was a folder. There’s no undo,” said a digital agency owner in a May 2026 G2 review.

Support & Response Times

Brevo offers email and live chat support on all paid plans, with response times under 2 hours during business hours (9 a.m.–6 p.m. CET). Phone support is available on Business and Enterprise tiers. Its knowledge base includes 200+ video tutorials — all under 3 minutes long.

Mailchimp provides email and chat on Essentials and above — but live chat is limited to 9 a.m.–5 p.m. EST. Phone support starts at $299/month (Premium). Its help center is extensive but text-heavy; fewer than 20% of articles include video walkthroughs.

When Mailchimp Is the Better Choice

Choose Mailchimp if:

• You rely heavily on Facebook and Instagram ads — Mailchimp’s native ad retargeting sync is smoother than Brevo’s (which requires UTM tagging and manual audience exports).
• Your team already uses Google Workspace — Mailchimp’s Gmail add-on lets you send campaigns directly from your inbox, with full template access and analytics previews.
• You need advanced A/B testing: Mailchimp lets you test subject lines, from names, content blocks, and send times simultaneously. Brevo limits A/B tests to one variable at a time on Starter.
• You manage multiple brands under one account: Mailchimp’s Teams feature (starting at $299/month) lets you create isolated workspaces with separate billing, permissions, and analytics. Brevo requires separate accounts — meaning separate logins and no consolidated billing.

When Brevo Is the Better Choice

Choose Brevo if:

• You send more than 10,000 emails/month and want predictable pricing — Brevo’s flat contact fee means your bill won’t spike if you run a flash sale or holiday campaign.
• You need SMS as part of your nurture flow — Brevo’s $0.0075/SMS (US) is cheaper than Twilio’s $0.0079 or MessageBird’s $0.0082, and it’s built in.
• Your list exceeds 5,000 contacts and you value CRM functionality — Brevo’s free deal pipeline and contact scoring replace the need for a $25/month HubSpot Starter seat.
• You prefer transparent, no-surprise billing — Brevo doesn’t charge extra for unsubscribes, spam complaints, or storage. Mailchimp does not charge for storage, but its active-contact model can misclassify contacts if your list hasn’t engaged recently, forcing unexpected upgrades.

Final Verdict: Who Should Switch?

You should consider switching from Mailchimp to Brevo if:

• You’re paying more than $25/month and aren’t using Mailchimp’s Premium features (predictive analytics, multivariate A/B testing, or Teams).
• You’ve added SMS or CRM tools separately — Brevo bundles them at no extra cost.
• Your list has >30% inactive contacts and you don’t plan to re-engage them soon — Brevo’s per-contact model treats them the same as active ones, but at a lower per-unit cost than Mailchimp’s tiered jump points.

You should not switch if:

• You depend on Mailchimp’s ad integrations or Google Workspace add-on.
• Your team relies on collaborative editing of campaigns — Brevo doesn’t support real-time co-editing like Mailchimp’s “Shared Drafts” feature.
• You need GDPR-compliant consent logs with version history — Mailchimp logs every consent update with timestamps and IP addresses; Brevo logs opt-ins but not revocations or edits.

One final note: Migration is straightforward. Both platforms support CSV imports, and Brevo offers a free Mailchimp import tool that maps lists, segments, and tags automatically. You’ll need to rebuild automations manually — but Brevo’s workflow UI is faster to learn than Mailchimp’s.

As of May 2026, Brevo remains the most cost-effective Mailchimp alternative for small businesses and growth-stage startups that prioritize simplicity, bundled features, and predictable billing — especially when contact volume climbs past 2,500.
