Brevo vs Warmly in 2026: Affordable Multichannel Campaigns vs Six-Figure Website De-Anonymization
Brevo starts at $9 a month and sends to people who opted in. Warmly starts at $10,000 a year and identifies the anonymous visitors on your website by name before autonomously starting a conversation. The gap between them is less about features and more about which budget tier you are actually in.
Brevo
Warmly- Warmly starts at $10,000/year with no free trial or self-serve signup; Brevo has a permanent free plan and a $9/month Starter tier available immediately.
- Warmly de-anonymizes website visitors at the individual person level, not just company; Brevo has no visitor identification capability of any kind.
- Warmly's Context Graph unifies site visits, CRM data, call transcripts, and chat logs into one account view for its AI agents; Brevo has no equivalent unified data layer.
- Full autonomous inbound automation on Warmly requires its AI Inbound Autopilot plan at $30,000/year; Brevo's most expensive published tier, Professional, is $539/month.
- Brevo includes SMS, WhatsApp, and a built-in CRM alongside email; Warmly connects to external CRMs like HubSpot and Salesforce rather than including one natively.
- Warmly customers report replacing $20,000 to $40,000/month SDR agency spend with the platform; Brevo has no comparable enterprise ROI case since it targets a different budget tier entirely.
Brevo and Warmly could not sit further apart on price or purpose despite both living in the marketing automation category. Brevo is a self-serve email, SMS, WhatsApp, and CRM platform priced by send volume, built for businesses messaging contacts who already opted in. Warmly is an enterprise GTM platform that identifies anonymous website visitors at the person level, unifies every signal about an account into a Context Graph, and deploys autonomous AI agents to engage them across chat, email, and ads, starting at $10,000 per year with no self-serve option. Almost no team is genuinely deciding between these two; the useful exercise is understanding why the price gap is this large and what each dollar actually buys.
The tools at a glance
Brevo
All-in-one email, SMS, WhatsApp, and CRM platform priced by emails sent, not contacts stored
Brevo is built for immediate, self-serve adoption. Pricing is published starting at $9/month, contacts are unlimited on every paid tier, and the bill scales with how many emails you send rather than your database size, a structure that suits businesses with large, selectively-emailed lists. A team can sign up and have a campaign live within hours, with no sales conversation required.
Its scope covers campaigns, transactional email, SMS, WhatsApp, live chat, push notifications, and a CRM with deal pipelines from Professional, with AI content generation from Standard upward. What it has no answer for is identifying who is browsing your website anonymously; Brevo works entirely with contacts that have already opted in and provided their information directly.
That is a reasonable and cost-effective scope for a small or mid-size business managing existing relationships. It offers nothing, however, to a team whose problem is converting anonymous, unidentified website traffic into a named lead before that visitor ever fills out a form.

Warmly
AI agents de-anonymize website visitors at the person level and autonomously run inbound and outbound GTM across chat, email, and ads
Warmly resolves anonymous website visitors down to the individual person, not just the company, by cross-referencing first-party tracking against its identity graph. The moment a named visitor lands on your site, the platform can pop an AI chat with full context, alert a rep in Slack, or fire a retargeting sequence, all before that person has filled out a single form.
The engine behind this is the Context Graph, a unified data layer ingesting site visits, emails, meetings, call transcripts, CRM records, and chat logs into a real-time account view, which AI agents consult before every action. The Inbound Agent runs chat and follow-up email autonomously, and the TAM Agent scores and segments your total addressable market for signal-triggered outbound rather than static list blasting.
None of this comes at small-business pricing. Plans start at $10,000/year for de-anonymization alone, scale to $20,000/year for inbound chat, and reach $30,000/year for full autonomous AI Inbound Autopilot, with GTM Signals and Warm Experiences priced as separate $10,000/year add-ons on top. There is no free trial or self-serve tier; every engagement starts with a sales conversation and a traffic-volume conversation about whether the math actually works.

Which should you choose?
BrevoWarmlyBrevoWarmlyBrevoWarmlyThe honest framing is that the price gap between these two is the whole story. Warmly is not a more expensive version of Brevo, it is solving a problem Brevo does not attempt to touch: converting anonymous website traffic into named, context-rich leads through an AI agent layer. A team should only be evaluating Warmly if it already has meaningful qualified traffic and either an SDR budget it wants to reallocate or an ABM program that needs to know exactly which named accounts are active on the site right now. Everyone else is looking at Brevo, or a similarly priced alternative, by default.
Bottom line
Choose Brevo unless you have a specific, budgeted reason to consider Warmly. Warmly only makes sense once your website traffic is substantial enough that identifying visitors at the person level and automating the first response has a clear, calculable ROI against its five-figure annual entry price, ideally with a current SDR agency spend it could offset. For nearly every small or mid-size business, Brevo's $9/month entry point covers the actual job that needs doing.
Frequently asked questions
Why is Warmly so much more expensive than Brevo?
Warmly starts at $10,000 per year because it is solving an enterprise-grade problem, identifying anonymous website visitors at the individual person level and running autonomous AI agents against a unified Context Graph of every account signal. Brevo starts at $9/month because it is a self-serve email, SMS, and CRM platform for contacts who have already opted in, a fundamentally lower-cost and lower-complexity job.
Does Brevo have any website visitor identification feature like Warmly?
No, Brevo has no capability to identify anonymous website visitors at all. It works entirely with contacts who have already provided their information directly, such as through a signup form or purchase. Warmly's entire product is built around resolving anonymous traffic to a named individual before that visitor ever fills out a form.
Is there a cheaper way to try Warmly before committing to a $10,000 contract?
No, Warmly does not offer a free trial, free tier, or self-serve signup at any price point. Every engagement starts with a sales conversation, and prospective buyers should specifically request to see person-level match rates for their own domain during that process, since accuracy varies meaningfully by industry and geography.
What traffic volume do I need before Warmly makes financial sense?
Warmly does not publish a specific traffic threshold, but the honest answer is that businesses with only a few hundred monthly B2B visitors are unlikely to see enough identified leads to justify the cost. Higher-traffic sites in competitive B2B categories, and companies currently spending on SDR agencies, are the more realistic fit for the ROI case Warmly is built around.
Can Brevo and Warmly be used together?
In principle yes, though they would serve very different roles. Warmly could identify and initiate contact with high-intent anonymous visitors, syncing qualified leads into a CRM, while Brevo could then run ongoing lifecycle email, SMS, and WhatsApp communication with those contacts once they convert into known customers. Most businesses evaluating Brevo, however, are not yet at the traffic or budget scale where adding Warmly makes sense.
Does Warmly include email marketing the way Brevo does?
Warmly includes automated email follow-up as part of its AI agent workflows, triggered by visitor identification and intent signals, but it is not a general-purpose email marketing platform with campaign templates, list segmentation, or SMS and WhatsApp the way Brevo is. The two tools' email capabilities serve different purposes rather than directly competing.
