Companies Using Brevo

With 10+ years in web crawling and technographic data analysis, I've examined Brevo's adoption across 108,617 enriched company profiles (a 75.3% match rate from 144,159 detected domains) on TechnologyChecker.io. Brevo (formerly Sendinblue) tells a story of European-first growth and WordPress-ecosystem dominance, but the current migration data shows specialists pulling at it from both ends.

Growth Trajectory

Brevo went from a single detected domain in March 2014 to 69,651 active domains at its December 2024 peak in our long-run detection history, before easing to 61,205 by July 2025, a 12.1% pullback over seven months. The May 2023 Sendinblue-to-Brevo rebrand and December 2025 unicorn financing (€500M) punctuated the growth story.

Our current crawl, which covers a wider slice of the web, now detects Brevo on 144,159 domains and the count is flat month over month (143,449 in July 2026, 144,159 in August). Those two figures are not like-for-like, because the set of domains we crawl turns over every month, with dead sites dropping out and newly discovered ones added, and our detection signals widen over time, so treat the step across the chart's 2025-to-2026 gap as coverage rather than growth.

Sales Signal: 7,069 domains have dropped Brevo since we began tracking it in March 2026, and the largest single destination is Klaviyo. Those are the warmest competitive leads in this install base.

Customer Profile

55.5% of Brevo's customers have 1-10 employees, and 83.3% have 50 or fewer. The 2010s-founded generation (38.64%) dominates, with a healthy 18.1% from 2020s-era companies. This concentration among digital-native micro-businesses aligns with Brevo's pricing: the free plan (300 emails/day, 100K contacts) and $9/month Starter tier specifically target early-stage companies that can't justify HubSpot or Klaviyo pricing.

The enterprise tail is thin but notable: 0.28% of the base has 10,001+ employees, including AXA, Sanofi, Michelin, and the United Nations. These names add credibility rather than volume.

Sales Signal: Target companies with 1-50 employees founded between 2010 and 2022. If they're European and running WordPress, conversion probability goes up. For enterprise prospecting, lead with the named logos: "AXA and Michelin trust Brevo" is a powerful opener for mid-market accounts considering the platform.

"Brevo's 75.3% enrichment match rate across 144,159 domains gives us one of the most complete firmographic profiles of any European marketing platform. The data shows Brevo isn't just competing on price; it's built a genuine ecosystem, especially among WordPress-powered businesses."

Industry & Geographic Concentration

No single industry exceeds 5% of Brevo's customer base. IT Services and IT Consulting leads at 4.54%, followed by Retail (4.52%), Software Development (3.81%), and Advertising Services (3.56%). This extreme diversification confirms Brevo as a horizontal platform, not a vertical specialist.

Geographically, the story is different. France accounts for 21.3% of all enriched customers and EU member states together reach 53.3%, against just 27.8% for the English-speaking markets that dominate every other platform in this category. The United States at 14.9% is growing but still trails France by nearly 7,000 companies. Italy (5.8%), the Netherlands (4.8%), and Spain (4.0%) fill out the European core.

Sales Signal: For vertical targeting, focus on IT services and retail companies in France and Germany; these are Brevo's sweet spots. The 21.3% French concentration means localized campaigns in French can reach over 22,000 prospects directly. For US targeting, position Brevo as the European-compliant alternative to MailChimp for companies with EU customers or data residency requirements.

Migration Patterns

Migration here counts domains we watched switch since March 2026, so the numbers are small by design and current by construction. Brevo still wins its oldest fight: 390 domains arrived from MailChimp against 278 leaving. But that is now the only corridor it wins.

The losses are concentrated and fast. Brevo is net negative against Klaviyo by 547 domains (691 out, 144 in), with 492 of those departures inside the last 30 days. It also loses to Mailgun (218 out, 72 in) and Amazon SES (130 out, 40 in). Klaviyo pulls the e-commerce-heavy customers who need deeper Shopify integration; the API-first senders pull the ones who only ever wanted transactional mail. Both are places where Brevo's generalist positioning falls short.

Sales Signal: Build a "Switch from MailChimp" landing page with transparent pricing comparisons, since that corridor still runs in Brevo's favour and post-Intuit price increases keep pushing cost-conscious SMBs away. For competitive defense against Klaviyo, emphasize Brevo's multi-channel capabilities (email + SMS + WhatsApp + chat) and lower cost of entry, because on pure Shopify integration the argument is already lost.

Tech Stack Ecosystem

WordPress dominates at 56.86%, the highest WordPress overlap of any email platform in our dataset. WooCommerce follows at 16.99%, Shopify at 8.26%, and PrestaShop at 3.05%, that last one a distinctly European signature you won't find on a US-centric platform. Google Analytics sits on 66.64% of Brevo domains.

The WordPress-WooCommerce corridor defines Brevo's tech identity. More than half of Brevo customers run self-hosted WordPress sites, and roughly one in six also uses WooCommerce. This makes Brevo the de facto email marketing choice for the open-source web stack.

Sales Signal: Partner with WordPress hosting providers (SiteGround, Bluehost, Cloudways) for co-branded landing pages. Create content targeting "best email marketing plugin for WordPress"; the 81,969 overlapping domains give you a data-backed proof point that no competitor can match. For WooCommerce stores, pitch Brevo's abandoned cart and post-purchase automation flows.

"With 56.86% WordPress overlap, Brevo owns the largest share of the WordPress email marketing ecosystem. That kind of platform integration through native plugins is hard to replicate. It's a genuine competitive moat, and right now it is the moat doing the work."
Mehmet Suleyman, CEO, TechnologyChecker.io

User Feedback Patterns

After looking at 1,398 G2 review mentions alongside our adoption data, here's what stands out: Brevo's biggest sell according to users is ease of use (324 mentions). The most frequent complaint, missing features (108 mentions), is something sales teams should proactively address, and it lines up exactly with the Klaviyo outflow. The 2.7:1 positive-to-negative ratio suggests overall satisfaction, but the cons aren't trivial.

Customer Sentiment (G2)

G2 reviewers validate what our market data suggests about Brevo. The leading positive signal is ease of use (324 mentions), while missing features (108 mentions) surfaces repeatedly as a concern. These review patterns help inform competitive strategy.

• MailChimp corridor still positive: 390 in against 278 out since March 2026
• Klaviyo is the threat: net -547 domains, with 492 departures in the last 30 days alone
• Micro-business core: 55.5% have 1-10 employees, pricing designed for SMBs
• Unicorn status: €500M raise in Dec 2025 positions Brevo for product expansion

Sales Applications

Outreach Template: "Hi [Name], I noticed [Company] runs WordPress and handles marketing through [current tool]. 57% of Brevo's user base runs WordPress, and the native plugin means setup is measured in minutes. Our data shows [specific insight about their stack]. Worth a 10-minute look at the cost savings?"

Targeting Strategy: Filter for companies with 1-50 employees, founded 2010-2022, in France, Germany, or Italy, running WordPress + WooCommerce. This profile matches Brevo's ICP almost exactly and represents a high-conversion segment for both Brevo sales teams and agencies recommending the platform.

Competitive Angle: Lead with pricing transparency against MailChimp (Brevo free: 300 emails/day + 100K contacts vs. MailChimp free: 500 contacts + no automation). For the EU market, emphasize data residency. "Your data stays in Europe" is the differentiator that US-based competitors can't easily match.
