Brevo Review 2026: The Email Tool That Replaced Mailchimp for My Agency Leads

i used to pay Mailchimp $90/month for 5,000 contacts and a clunky automation builder. every new lead from my Google Ads campaigns went into a “welcome” drip that took forty minutes to build and broke twice a quarter. the free tier was gutted: 250 contacts, 500 emails, no automation. something had to change. Brevo has a free forever plan: 300 emails/day, no credit card, 500 contacts. it replaced my Mailchimp setup in under a week.

Brevo (formerly Sendinblue) is an all-in-one marketing platform: email, SMS, WhatsApp, marketing automation, CRM, and transactional messaging. founded in 2012, 600,000+ customers, 2500+ G2 reviews. this Brevo review covers the pricing math, the features that actually matter for lead-gen agencies, how it stacks up against Mailchimp, and who should (and shouldn’t) switch in 2026.

the short version: yes, for lead-gen agencies and media buyers who want real automation at a fair price and don’t need 330+ integrations. no, if you’re a high-volume ecommerce store sending 50,000+ emails a week or you need a massive integration library.

What Is Brevo?

Brevo is an all-in-one customer platform that combines email marketing, SMS, WhatsApp, marketing automation, transactional email, and a built-in CRM, priced by emails sent rather than contacts stored. it targets small-to-midsize businesses, agencies, and solopreneurs who want real marketing automation without the Mailchimp price tag. the platform started as Sendinblue in 2012, founded by Armand Thiberge in Paris and Bangalore, and rebranded to Brevo in 2023 to reflect the expansion beyond just email.

what makes Brevo different from Mailchimp at the structural level: pricing model. Mailchimp charges by the number of contacts on your list, including unsubscribed ones. Brevo charges by the number of emails you actually send. if you have a list of 50,000 leads but only email 5,000 of them each month, Brevo’s pricing favors you. Mailchimp’s punishes you for the dead weight.

the core product areas:

• Email marketing: drag-and-drop builder, templates, send-time optimization, A/B testing
• Marketing automation: visual workflow builder, behavioral triggers, lead scoring (Professional+)
• Multi-channel: SMS, WhatsApp, web/mobile push notifications (Professional+)
• Transactional email: SMTP relay, API, dedicated IP option
• CRM: contact management, deal pipeline, custom attributes (Sales Essentials included in Starter+)
• Landing pages & forms: built-in signup forms and standalone landing pages (Standard+)

for my agency use case: lead capture from Google Ads + Meta campaigns, automated nurture sequences, handoff to sales, Brevo covers the entire workflow without a single third-party tool. that’s the actual win.

Brevo Pricing Breakdown

here’s the verified 2026 pricing straight from Brevo’s pricing page. the headline numbers are clean. the catch is understanding what “priced by emails sent” means as your volume grows. for the most current numbers, see the live pricing page.

pricing verified September 2026 from brevo.com. SMS credits sold separately on all tiers. annual billing available.

the pricing math that matters for agencies

three things most reviews don’t spell out:

1. Starter caps contacts at 500: yes, you read that right. the free plan holds 100,000 contacts but the $9/month Starter plan caps you at 500 contacts. this is the single most confusing thing about Brevo’s pricing. you’re paying more to store fewer contacts, but you’re paying to remove Brevo branding and unlock features, not to store more. for agencies with large lead lists, this means you either stay on the free plan (with Brevo branding) or jump to Standard where the cap lifts.
2. you pay per email sent, not per contact stored: if you have 10,000 leads but only send to 2,000 of them each month, you’re not penalized for the other 8,000. this is Brevo’s structural advantage over Mailchimp for lead-gen agencies with high list-to-send ratios.
3. Professional at $499/mo is a cliff, not a slope: Standard at $18/mo is excellent value. Professional at $499/mo is for teams that genuinely need multi-user access, WhatsApp/push channels, and a deliverability specialist. most agencies will never need it.

if you’re pulling campaign data into dashboards to track lead quality, you’ll want to pair Brevo with a reporting tool like Two Minute Reports, it connects to 30+ data sources and makes cross-channel attribution actually legible.

Brevo vs Mailchimp: Honest 2026 Comparison

the question every agency asks. here’s the real comparison, not the feature-checkbox table.

pricing model: emails sent vs contacts stored

Brevo charges by emails sent. Mailchimp charges by contacts stored. this is the single biggest structural difference. Mailchimp counts every contact, subscribed, unsubscribed, non-subscribed, against your plan limit. Brevo doesn’t.

what this means in practice:

• 50,000 contacts, 5,000 emails/month → Brevo Standard at $18/mo vs Mailchimp Essentials at ~$90/mo
• 5,000 contacts, 5,000 emails/month → Brevo Starter at $9/mo vs Mailchimp Essentials at $13/mo
• 1,000 contacts, 50,000 emails/month → Brevo Professional at $499/mo vs Mailchimp Standard at ~$45/mo

Brevo wins for high-list, low-send-volume. Mailchimp wins for low-list, high-send-volume. for lead-gen agencies that collect leads continuously but nurture in batches, Brevo’s model is structurally cheaper.

free plan

Brevo’s free plan is the real thing: 300 emails/day (~9,000/month), up to 100,000 contacts, basic automation, transactional SMTP. Mailchimp’s free plan was gutted in January 2026: 250 contacts, 500 emails/month, no automation, no scheduling, Mailchimp branding on every email. support expires after 30 days on Mailchimp’s free tier.

if you’re a solopreneur or just starting, Brevo’s free plan is functional. Mailchimp’s is a demo.

marketing automation

Brevo’s visual workflow builder is available on Standard ($18/mo). Mailchimp’s “customer journeys” requires Essentials ($13/mo) and up, with the full branching logic locked behind higher tiers. in side-by-side testing, Brevo’s builder is faster to set up and less prone to the “why did my contact get stuck” debugging that plagues Mailchimp journeys.

integrations

Mailchimp wins on integration count: 330+ native integrations vs Brevo’s 150+. if your stack requires deep native connections to Shopify, Salesforce, QuickBooks, or niche ecommerce platforms, Mailchimp has broader coverage. Brevo covers the essentials (WordPress, Shopify, WooCommerce, Zapier, Salesforce, Zoho, Pipedrive) but you may need Zapier as a bridge for tools Mailchimp connects to natively.

for lead-gen agencies running Google Ads + Meta + Brevo, the native integrations cover 95% of use cases. for complex ecommerce stacks, Mailchimp’s integration library matters more.

deliverability

independent tests consistently show Mailchimp scoring higher on inbox placement rates. Brevo’s deliverability tools (authentication wizard, IP warmup) are solid but not Mailchimp-class. for opted-in lead follow-up, both perform well. for cold outreach or purchased lists, neither will save you, and both will suspend your account if you try.

the bottom line

Brevo Pros and Cons

honest list after running Brevo for agency lead follow-up alongside ad campaigns.

what works

• pricing model rewards lead-gen workflows: pay for emails sent, not contacts stored. if you collect 1,000 leads/month but only email 200 of them weekly, you’re not paying for the dead weight.
• free plan is genuinely usable: 300 emails/day, 100K contacts, basic automation. most competitors offer a demo, Brevo offers a real starting point.
• marketing automation at $18/mo: visual workflow builder, behavioral triggers, conditional logic. Mailchimp charges more and delivers less flexibility.
• CRM included from Starter: contact profiles, deal pipeline, engagement history. no separate CRM subscription needed for agency workflows.
• transactional email separate from marketing: deliverability for transactional messages stays clean even if marketing sends hit spam.
• multi-channel consolidation (Professional): email + SMS + WhatsApp + push in one platform, no separate subscriptions.
• G2 awards for enterprise and small business: 2500+ reviews, TrustRadius top-rated email marketing 2026.

what doesn’t work

• Starter caps contacts at 500: the free plan holds 100K contacts but Starter ($9/mo) drops you to 500. counterintuitive pricing that confuses every new user.
• Standard plan limited to 1 user seat: if you have a team (virtual assistant, copywriter, media buyer), you need Professional at $499/mo for multi-user. that’s a steep jump from $18.
• fewer integrations than Mailchimp: 150+ vs 330+. for complex ecommerce stacks, you’ll need Zapier as a bridge.
• deliverability trails Mailchimp: historically lower inbox placement in independent tests. fine for opted-in leads, not for aggressive cold outreach.
• Professional tier is a cliff: $499/mo for WhatsApp, push, multi-user, and deliverability specialist. most agencies won’t need it, but the gap between Standard ($18) and Professional ($499) is enormous.
• reporting on lower tiers is basic: heatmaps, advanced analytics, and comparative reports require Standard or above. free and Starter get surface-level stats.

the free plan replaced my $90/month Mailchimp subscription for lead follow-up. that’s not a feature claim, that’s the actual bill difference. after one month on Brevo

Who Should Use Brevo?

three groups genuinely benefit. if you fall into one of these, the math works.

lead-gen agencies running paid ads

the core target. Brevo pays for itself if you’re collecting leads from Google Ads / Meta Ads and running automated nurture sequences. the pricing model favors high list-to-send ratios (lots of leads, targeted sends). automation at Standard ($18/mo) replaces Mailchimp’s $90+ plans. CRM is built in. landing pages are built in. one tool, one bill.

if you’re running ad campaigns and need to track which leads convert across channels, Two Minute Reports connects your ad platforms to Looker Studio and gives you a cross-channel view that Brevo’s reporting alone can’t match.

solopreneurs and freelancers

if you’re a one-person agency, freelance media buyer, or consultant, the free plan covers your basic email marketing. upgrade to Standard ($18/mo) when you need automation and remove the Brevo branding. at one seat, you never hit the multi-user problem.

nonprofits and community organizations

Brevo’s free plan holds 100,000 contacts, you can manage a large community list without paying. paid Starter caps at 500 contacts, so nonprofits with large lists need to stay on free or jump to Standard. note: Brevo’s nonprofit discount (15%) only applies to the Enterprise plan, not the tiers most nonprofits actually use.

Who Shouldn’t Use Brevo?

three groups should look elsewhere.

high-volume ecommerce sending 50,000+ emails/week

if you’re running promotional email at scale: daily sends, 100,000+ emails/month. Brevo’s per-email pricing becomes expensive fast. Mailchimp’s contact-based pricing often works out cheaper for high-frequency senders, and platforms like Klaviyo are purpose-built for ecommerce volume.

teams needing multi-user access on a budget

Standard ($18/mo) is single-seat. if you need 3-5 team members with access, you’re looking at Professional at $499/mo. Mailchimp offers multi-user on lower tiers. for teams on a budget, this Brevo pricing gap is real.

companies needing 300+ integrations

if your tech stack requires deep native connections to Shopify Plus, NetSuite, or niche ecommerce tools, Mailchimp’s 330+ integrations will save you from building Zapier bridges. Brevo covers the essentials but not the long tail.

Brevo Alternatives

when to pick each one

• pick Brevo if you’re a lead-gen agency or media buyer, you want real automation at a fair price, and your list-to-send ratio is high (more contacts than monthly emails).
• pick Mailchimp if you need 330+ integrations, you’re a high-volume sender (contact-based pricing works in your favor), or brand recognition matters to your clients.
• pick Klaviyo if you’re an ecommerce store doing promotional email at scale and need predictive analytics.
• pick ActiveCampaign if you need the deepest automation builder available and CRM features that go beyond contact storage.

Final Verdict

if you’re running lead-gen campaigns and paying Mailchimp $50-100/month for basic automation, Brevo will replace it at a fraction of the cost. the free plan alone handles 300 emails/day. Standard at $18/mo gives you the full automation builder, landing pages, A/B testing, and CRM. for agencies collecting leads from Google Ads and Meta Ads, Brevo’s pricing model (pay per email sent, not per contact stored) is structurally the right fit.

the two scenarios where Brevo is unequivocally the right call: (1) you’re a lead-gen agency with a growing contact list but targeted send volume, Brevo rewards exactly this pattern, and (2) you’re a solopreneur who needs real automation without the Mailchimp price tag: the free plan covers you until you’re ready for Standard.

the counter-case: high-volume ecommerce senders, teams needing multi-user on a budget, or companies needing 330+ native integrations, Mailchimp or a purpose-built tool serves you better. Brevo’s Professional tier at $499/mo is a cliff, not a slope, and the Starter plan’s 500-contact cap is a genuine annoyance.

if you’re on the Brevo free plan, you can set up your entire lead follow-up workflow, forms, welcome automation, nurture sequences, without entering a credit card. the free plan is the real thing, not a demo. start there, upgrade to Standard when you need the full automation builder.
