Brevo: Email Marketing at Send-Volume Pricing (Not Per-Contact)
Brevo (formerly Sendinblue) is the all-in-one marketing platform we recommend for SMB marketers, bootstrapped B2B / e-commerce founders, and lean service businesses. Email, automation, transactional API, SMS, WhatsApp, landing pages, and a basic CRM under one workspace — priced by emails sent per month, not contact count, which is structurally cheaper than Mailchimp, ActiveCampaign, or HubSpot Marketing for the large-list / moderate-send shape most operators actually have. Honest review: where Brevo wins, where it doesn't, and when to pay for Klaviyo or HubSpot instead.

Where this lands
Why we recommend Brevo
1
The friction
Per-contact pricing is structurally wrong for most SMB lists.
Default email platforms — Mailchimp, ActiveCampaign, HubSpot Marketing, Klaviyo — charge by contact count. Every contact you add bumps your tier, regardless of whether you actually email them. A 25K-contact list on Mailchimp Standard runs ~$135/mo even if you only email twice a week. ActiveCampaign Plus on the same list runs ~$135-$229/mo. HubSpot Marketing Pro starts at $890/mo. The math punishes the most common SMB shape: large lists you segment into smaller send populations — lifecycle nurture flows, win-back campaigns, infrequent broadcast newsletters where contacts accumulate but send volume stays moderate.

Send-volume pricing math
Multi-channel under one workspace — email + SMS + WhatsApp + transactional + landing.
Most SMB marketing stacks stitch 3-5 tools: Mailchimp for email, Postmark for transactional, Twilio for SMS, Unbounce for landing pages, HubSpot for CRM. Brevo collapses email + automation + transactional API + SMS + WhatsApp + landing pages + light CRM into one workspace, sharing sender infrastructure and contact data. For solo operators and lean marketing teams, workspace consolidation beats best-of-breed depth on TCO and operational overhead — fewer vendor relationships, one billing line, one set of segmentation logic. The pricing curve stays favorable for the large-list / moderate-send shape through ~250K contacts and ~150K monthly sends; above that, you're into Professional ($499/mo) where AI segmentation and advanced ecommerce earn the premium.

Confirm current pricing on each vendor's site — list prices shift quarterly and tier boundaries move.
What Brevo gets right
Structural pricing
Send-volume pricing instead of per-contact
The structural inversion of the Mailchimp / ActiveCampaign / HubSpot Marketing model. For SMB lists with moderate send cadence — the most common shape — Brevo's pricing math beats every contact-tier competitor by 2-4x at scale.
Free tier
Real free plan, 300 emails/day, unlimited contacts
Not a 14-day trial. Ship your first automations, transactional flows, and broadcast campaigns before paying anything. Almost no other major email platform offers this with unlimited contacts.
One workspace, shared contact data, shared sender infrastructure. Collapses 3-5 SaaS line items (Mailchimp + Postmark + Twilio + Unbounce + maybe a CRM) into one bill — fewer vendor relationships, one set of segmentation logic.
Transactional API
Competitive with Postmark and SendGrid
Order receipts, password resets, app notifications, event-triggered messages. Shares sender domain + IP infrastructure with marketing campaigns — most operators paying two vendors (Mailchimp + Postmark) are doing it with what Brevo bundles.
Authentication
Operator-friendly sender domain setup
Clear SPF / DKIM / DMARC workflow with working validation. Not the prettiest UI but the docs are honest about what to add and the verification doesn't break under standard DNS providers (Cloudflare, Route 53, GoDaddy, Namecheap).
AI segmentation
AI segmentation + contact scoring on Professional
At $499/mo (Professional), Brevo bundles AI segmentation, predictive contact scoring, and advanced ecommerce automations. Reasonable mid-market depth without HubSpot Marketing Pro's $890/mo entry point.
Workspace consolidation
Light CRM + marketing under one vendor
The CRM module handles contact records, basic pipeline stages, and deal tracking. Enough for solo operators and service businesses that want light deal visibility without standing up HubSpot or Pipedrive alongside their email tool.
When NOT to pick Brevo
Shopify e-commerce
Deep Shopify-native e-commerce automation
Klaviyo wins on Shopify-native depth: product-feed automation, predictive segmentation, dynamic recommendations, and integration depth across Shopify + WooCommerce + BigCommerce. If your store does $500K+/yr GMV on Shopify and email is the #1 marketing channel, buy Klaviyo.
Sales-led B2B
Sales-led B2B where CRM is the anchor
Brevo's CRM is functional but isn't built for reps running cadences, multi-stage opportunities, or revenue forecasting. Pair Brevo with HubSpot Free CRM, Pipedrive, or Close for sales-led motions — don't try to use Brevo CRM as the system of record.
Automation depth
Complex multi-branch automation logic
ActiveCampaign and Klaviyo have deeper automation editors with more advanced conditional logic, recipes, and templates. Brevo's automation handles standard lifecycle flows well (welcome, nurture, win-back, abandoned cart) but caps out for automation-heavy mid-market motions.
Branding-removal hack
$9/mo 'Remove Brevo branding' add-on at sub-Business tiers
Free, Starter, and lower tiers append a 'Sent with Brevo' tag. The $9/mo add-on strips it. On Starter the math gets awkward — $9 plan + $9 branding removal = $18, which is the same price as Business that bundles more features. Skip the hack and go straight to Business.
At enterprise volume, dedicated ESP platforms (Iterable, Braze, Customer.io) or purpose-built high-volume infra (Amazon SES + custom front-end) earn their cost on deliverability, observability, and account management. Brevo Professional ($499/mo) handles up to mid-volume; above that, you're shopping different tools.
UX polish
UI/UX is less polished than Mailchimp or ActiveCampaign
Brevo's editor and dashboards are functional but feel a half-step behind the category leaders on craft. Not a dealbreaker for operators who care about pricing math and feature coverage over polish — but if UX matters more than TCO, Mailchimp's editor wins.

Patterns we see with Brevo
Bootstrapped B2B nurture: Founders and early-stage marketers running long-cycle nurture flows on 10K-50K contact lists with moderate send cadence (1-2x/week). Brevo's send-volume pricing wins decisively against Mailchimp / ActiveCampaign at this shape — typical savings of 50-70% over a year while keeping the same send capability.
Service business newsletters + transactional: Agencies, consultancies, and service businesses running monthly client newsletters plus transactional email (proposals, invoices, scheduling confirmations). Bundling marketing + transactional under one Brevo workspace eliminates the Mailchimp + Postmark + Calendly-stack-of-stuff overhead.
Course creators + community-led businesses: Email-first creators running launch sequences, drip courses, and community newsletters. Brevo's automation handles standard course-launch flows (welcome → waitlist → launch → post-purchase) and the SMS / WhatsApp channels add reach for launch days without standing up Twilio separately.
Brevo + HubSpot Free CRM for sales-led SMB: Pair Brevo for marketing email + automation + transactional, HubSpot Free CRM for sales pipeline and contact management. Route leads bidirectionally with a Zapier or n8n bridge. This pattern earns the most marketing-stack ROI per dollar for sales-led SMB teams under 10 reps.
Multi-channel SMB marketing under one workspace: SMB marketers running email + SMS + WhatsApp + landing pages + transactional API from one bill. Consolidation play — fewer vendor relationships, one set of segmentation logic, one sender infrastructure. Used by lean marketing teams of 1-3 people who would otherwise be context-switching across 4-5 tools.
FAQ
Brevo vs Mailchimp — which is cheaper for my list size?+
Depends on the shape of your motion. Mailchimp charges per contact, so a 25K-contact list on Standard runs ~$135/mo even if you only email twice a week. Brevo charges per email sent — that same 25K list sending 2x/week (~200K emails/mo) lands on Brevo Business ~$69-$129/mo. The bigger the gap between your contact count and your monthly send volume, the more structurally cheaper Brevo gets. Flip it around: if you mail your full list 5x/week (high send-to-contact ratio), Mailchimp's contact-based math can win.
What is the email-volume vs per-contact pricing difference, exactly?+
Most email platforms (Mailchimp, ActiveCampaign, HubSpot Marketing, Klaviyo) tier pricing by how many contacts are in your list — every contact you add bumps you up, regardless of whether you actually email them. Brevo prices by emails sent per month — you can hold 250K contacts in the database and pay based on what you actually send. This matters for SMB and bootstrapped teams with large lists they segment into smaller send populations: lifecycle nurture flows, win-back campaigns, infrequent broadcast newsletters. The structural break-even is roughly: if monthly emails sent ÷ contact count is below ~10, Brevo's math wins. Above ~15, per-contact pricing wins.
Can I run transactional + marketing email under one Brevo workspace?+
Yes — and that's one of Brevo's quiet wins. The transactional email API is competitive with Postmark and SendGrid for order receipts, password resets, app notifications, and event-triggered messages, and it shares the same sender domain + IP infrastructure as your marketing campaigns. Most operators using Mailchimp + Postmark or Klaviyo + SendGrid are paying two vendors for what Brevo does under one contract. The caveat: at very high transactional volume (10M+/mo), purpose-built transactional services like Postmark still have a deliverability and observability edge.
How good is the Brevo CRM, honestly?+
Functional, not the wedge. The CRM module handles contact records, basic pipeline stages, and deal tracking — fine for a solo operator or service business that wants light deal tracking alongside their email. It is not the right CRM for a sales-led B2B motion with reps running cadences, multi-stage opportunities, or revenue forecasting. If sales is the engine, pair Brevo (email + marketing automation) with a real sales CRM — HubSpot Free CRM, Pipedrive, or Close — and route leads bidirectionally.
What is Brevo's deliverability story?+
Standard for the SMB email category — competitive when you do the basics right (SPF + DKIM + DMARC verified, sender reputation managed, list hygiene maintained), thin if you treat it as a fire-and-forget tool. Brevo's sender domain authentication workflow is operator-friendly: clear DNS records to add, working validation, and dedicated IP available on Business+ tiers when your monthly volume justifies one (typically ~50K+ sends/month consistent). Dedicated IPs are an extra ~$130-145/mo and only worth it if you have the volume to warm and maintain reputation.
Why is there a $9/mo 'Remove Brevo branding' add-on?+
Brevo's Free, Starter ($9), and lower-end tiers append a small 'Sent with Brevo' tag to outgoing emails. The $9/mo branding-removal add-on strips it. Business tier ($18+/mo) and above remove the tag without the add-on. Honest read: on Starter the math gets awkward — your $9/mo plan effectively becomes $18/mo to look professional, which is the same price as the Business tier that bundles more features anyway. If you care about branding (and most operators do), skip Starter + branding-removal and go straight to Business.
Brevo vs ActiveCampaign for automation depth?+
ActiveCampaign wins on pure marketing-automation depth — more advanced conditional logic, deeper integrations with sales-CRM workflows, and a more mature ecosystem of templates and recipes. Brevo's automation is solid for SMB lifecycle flows (welcome series, abandoned cart, post-purchase nurture, win-back) but caps out for complex multi-branch scoring + segmentation logic. The tradeoff: ActiveCampaign uses per-contact pricing, so it gets expensive faster. For lean teams running standard lifecycle automation, Brevo's depth is enough and the pricing math wins. For automation-heavy mid-market motions, ActiveCampaign earns its premium.
Brevo vs Klaviyo for e-commerce — which one?+
Klaviyo wins on Shopify-native e-commerce depth. Product-feed automation, predictive segmentation, dynamic recommendations, and integration depth across Shopify + WooCommerce + BigCommerce are the engine of Klaviyo, and Brevo is one step behind on every dimension. Brevo's e-commerce features exist (abandoned cart, post-purchase, browse abandonment) but are not the wedge. The honest split: if your store does $500K+/yr GMV on Shopify and email is the #1 marketing channel, buy Klaviyo. If you're earlier or running a non-Shopify store where multi-channel (email + SMS + transactional) under one workspace beats deep product-feed flows, Brevo wins on TCO.
