Brevo Review 2026: The Best Value Here, If It Lets You In
The Best: Bills emails sent, not contacts stored, so the list can grow free
The Worst: Account protection suspends new accounts before the first campaign
TL;DR, Should you still use Brevo in 2026?
Brevo is the best value on this site, and the reason is structural rather than promotional. It bills on emails sent, not contacts stored. Every other platform we have profiled charges you for the size of your database. Brevo charges you for how much you mail it. If your list is large and you mail it occasionally, that single difference is worth more than any feature comparison, and at least 35 of the 157 distinct reviews we read praise the value directly.
It is also the only platform in this group that has an SMTP relay at all. MailerLite, Flodesk, Constant Contact and Klaviyo all publish none. Brevo gives you marketing campaigns, transactional mail, an official MCP server and a permanent free tier from one account.
Now the catch, and it is a real one. At least 17 of those 157 reviews describe account suspension, blocking or an abrupt verification process, and almost all of them are four and five-star reviews. People who love this product describe being locked out of it before they sent anything. “The automatic suspension immediately after creating the account,” writes one five-star reviewer. “Things do happen without warning. My account got suspended,” writes another.
The context you need before evaluating Brevo in 2026
Start with the name, because the measurement is striking. Brevo was Sendinblue until May 2023. Three years later, 6,600 people a month in the United States still search for sendinblue. That is seventeen times the volume of brevo review and a sixth of the volume of brevo itself. The rebrand has not finished landing, and it means a large share of the advice you will find about this product was written under a different name and may describe different pricing.
The company is French, founded in 2007, and has grown into something broader than an email tool: campaigns, transactional sending, SMS, WhatsApp, a CRM and a chat widget on one contact database. That breadth is the product thesis, and the review corpus both confirms it and prices it. Reviewers praise the all-in-one scope and then, in the same breath, call it “a vast software with countless functions” and “rich in features, options difficult.”
The structural fact that should govern your decision is the billing basis. Brevo meters emails sent. It does not charge for contacts stored. Read that against Klaviyo, where 51 of 148 reviewers complained about being billed per stored profile, and the two platforms are exact opposites of each other on the one axis that determines a marketing bill. A ten-year-old list of one-time buyers costs nothing to hold here. It is the whole cost base at Klaviyo.
The second structural fact is that Brevo publishes a real SMTP relay at smtp-relay.brevo.com. The legacy smtp-relay.sendinblue.com hostname still resolves as an alias. Nothing else in this comparison group has one. If your application sends receipts and your marketing team sends campaigns, this is the only platform here where those are the same account and the same contact database.

What Brevo does well
The billing model is the product, and it is the right way round
Emails sent, not contacts stored. That sentence is worth more to a growing list than any feature on any comparison grid, and reviewers say it in their own words: “Large contact capacity without cost increase,” “Contacts won’t cost more,” “free plan for unlimited contacts.” At least 35 of 157 excerpts praise the value or the pricing, the second-largest praise cluster in the corpus. Put next to Klaviyo, where a third of reviewers complain about exactly the opposite model, this is the clearest structural advantage we have measured on any platform.
It is the only platform in this group with an SMTP relay
MailerLite routes transactional mail to a sibling product. Flodesk, Constant Contact and Klaviyo publish no relay at all and never have. Brevo publishes smtp-relay.brevo.com and lets you send receipts and campaigns from one account against one contact database. For a small team, that is one vendor instead of two, one deliverability reputation instead of two, and one bill. Our SMTP settings tab has the ports and key management.
Support is answered by people, and answered well
At least 33 of 157 excerpts praise support, against at least 8 that criticise it. Capterra scores customer service at 4.5. The reviews name individual agents, which is a signal you do not get from a scripted queue: “Fantastic service from Romeo,” “Customer service is great with Isabella,” “really good, happy, friendly, and real human support.” Several note it is good even on the free tier, which is rare.
The developer surface is unusually complete for a marketing tool
A v3 REST API at api.brevo.com/v3, 7 official SDKs, an api-key header with no request signing to get wrong, and an official MCP server. Only Brevo and Klaviyo ship official agent tooling among the marketing platforms we have profiled; Mailchimp and Constant Contact ship none. One reviewer praises “excellent API documentation, seamless Rust integration”, which is not a sentence you find in a Constant Contact review.
The all-in-one scope is real, not a feature list
Email, SMS, WhatsApp, CRM, chat and transactional on one contact database. Reviewers describe running a whole small business off it: “Free marketing, CRM, tasks, organized tracking,” “We use Brevo as a free-access CRM,” “Breadth on platform: email, SMS, WhatsApp.” The next section explains what that breadth costs, but the breadth itself is not marketing copy.
Where Brevo falls short
Account protection locks people out before they have sent anything
This is the finding of this review, and it is the reason to read past the star rating. At least 17 of 157 excerpts describe suspension, blocking, or an abrupt verification or due-diligence process. The wording is consistent and it is specific:
- “Account suspended immediately; verification required initially” – five stars
- “The automatic suspension immediately after creating the account” – five stars
- “Temporary account blockage without prior notice” – five stars
- “Things do happen without warning. My account got suspended” – four stars
- “Account suspension for unclear reason. We sent a campaign” – five stars
- “Overly sensitive algorithm; campaigns suspended unnecessarily” – five stars
- “Didn’t receive any notifications or warnings in my dashboard or email” – five stars
Read the star ratings on that list again. These are not angry ex-customers. These are people who rated Brevo five out of five and still chose to spend their Cons field on being locked out. That combination is what makes this a product characteristic rather than a support anecdote, and it is not in any feature comparison anywhere.
The charitable reading is that a platform with a permanent free tier and an SMTP relay is a magnet for abuse, and aggressive screening is how it protects the shared pool that everyone else’s deliverability depends on. That is probably true, and it may even be why the deliverability holds up. It is still a bad first week, and you should plan for it: verify your domain and your business details before you need to send anything urgent.
The breadth is wide and the depth is ordinary
At least 28 of 157 excerpts say the advanced features, customization or templates stop short. The phrasing repeats: “advanced customization limited compared to higher-end,” “advanced features feel limited compared to,” “limited design flexibility, basic pop-ups,” “landing page builder feels half-baked,” “drag and drop limits creativity.” Brevo does eight things adequately rather than one thing brilliantly. If any single one of those eight is your core requirement, a specialist will beat it.
Eight products in one interface is eight products in one interface
At least 21 excerpts name the complexity, the learning curve or the navigation. “Complex dashboard,” “a vast software with countless functions,” “very confusing interface and navigation,” “left-hand menu bulky, contact list confusing.” A recurring specific complaint is worth flagging because it will cost you money if you miss it: several reviewers find the contact and recipient counts confusing or mismatched. On a platform that meters sends, understanding exactly who is in a send is not optional.
Automation is mid-tier, and that is the honest ceiling
The flows work and reviewers use them, but the depth is not there for real lifecycle marketing. Complaints name “limited automation workflow contacts,” automation that is “unintuitive,” and a “recurring difficulty implementing automations.” If your programme needs behavioural branching or revenue attribution, Klaviyo and ActiveCampaign are the honest answers, and you will pay considerably more for them.
Deliverability is the weakest measured number in the tested group
EmailToolTester puts Brevo at 88.3 percent inbox placement in its most recent published round. That is below Constant Contact at 91.7, MailerLite at 89.8 and Mailchimp at 89.5, and well below ActiveCampaign at 94.2. The corpus is kinder than the panel: at least 8 excerpts praise deliverability specifically and very few complain. Both are true, and the panel is the number you should plan against.
Two billing details reviewers wish they had known
First, purchased credits do not carry over, named directly by a reviewer who otherwise rated the product five stars. Second, several reviewers describe extra per-user fees: “cannot add users without additional fees,” “add marketeers without additional fees.” Neither is hidden, and neither is unusual. But on a platform chosen for its value, the things that are not metered by send are the things worth checking. Our pricing tab has the current ladder.
Account risk: not rated, and here is what we can and cannot say
What we can report is the corpus, and here it is unusually loud: 17 of 157 excerpts describe suspension, blocking or abrupt verification, overwhelmingly from four and five-star reviewers. Note the difference from a strict-AUP platform: nobody here describes being banned for what their business is. They describe being stopped for what their sending looked like, usually in the first days, usually resolved. That is a screening system, not a prohibited-industries list, and it should be read as one.
What real users actually say
We read 7 pages of Capterra reviews, 175 rendered rows, and deduplicated on the exact record. At least 18 rows were the same reviews re-served across pages, leaving roughly 157 distinct. That is a 10 percent duplicate rate, the highest we have measured on any profile, and it is a property of how this listing paginates rather than of the reviews themselves.
Praised most often
- Ease of use and clean interface – at least 80 of 157 excerpts
- Value for money and the free tier – at least 35
- Customer support, often by name – at least 33
- Deliverability and reliability – at least 8
- All-in-one breadth: email, SMS, WhatsApp, CRM – repeatedly, across every page
Complained about most often
- Advanced features, customization and templates limited – at least 28
- Interface complexity and learning curve – at least 21
- Account suspension, blocking, abrupt verification – at least 17
- Contact limits, credits and per-user fees – at least 14
- Support response time – at least 8
The distribution is heavily positive: 3 one-star, 1 two-star and 4 three-star in 157, with the rest at four and five. Capterra’s own aggregate across 3,512 reviews is 4.6, and our recent sample is consistent with it.
The mixed cluster is the breadth itself, and it is the most interesting one we have measured. The same property is the top reason people love this product and a top reason they struggle with it. Praise: “all-in-one platform, efficient contact management,” “centralizes email, SMS within single platform,” “free marketing, CRM, tasks.” Criticism: “platform rich in features, options difficult,” “there is so much functionality that sometimes it’s hard,” “a vast software with countless functions.” Nobody is wrong. Breadth is a feature until it is a map you have to learn.
The second cluster is support, praised at least 33 times and criticised at least 8. The split is about channel and timing rather than quality: the praise names individual humans, the criticism names response time and the absence of real-time chat. “Customer care tends to be intermittent at busy times” is the fairest summary a reviewer offered.
The third is the account-protection system, and it does not split at all. Nobody praises it. Seventeen people, mostly happy customers, describe it as abrupt, unexplained or immediate. When a complaint appears only in one direction and mostly inside five-star reviews, it is not a matter of taste.
Ratings breakdown
Six categories, scored 1 to 10. The overall is the unweighted arithmetic mean, rounded to one decimal.
| Category | Rating | Best alternative for this |
|---|---|---|
| Ease of use Interface clarity, and the first week | 7.5 | MailerLite if you want one product instead of eight |
| Automation depth Branching, triggers, segmentation | 6.0 | Klaviyo for ecommerce, ActiveCampaign for B2B |
| Deliverability Inbox placement, measured | 7.5 | Constant Contact at 91.7 percent, or Postmark for transactional |
| Support Response time, quality, escalation path | 8.0 | Ties MailerLite at the top of the category |
| Pricing value Cost per outcome, and the billing basis | 8.5 | Brevo wins this category. Highest score on the site. |
| API and MCP Developer experience, agent support, SMTP | 8.5 | Postmark or Klaviyo, both at 9.5 |
| Overall | 7.7 | Highest-rated marketing platform on SMTPedia, just under Postmark at 7.8 |
Who should still use Brevo
Recommended if
This is the case Brevo wins outright, and it is not close. Billing on emails sent, not contacts stored means a decade of accumulated contacts costs nothing to hold. On Klaviyo the same database is the entire bill, and 51 of its 148 reviewers said so.
Brevo is the only platform in this comparison group with an SMTP relay. Receipts, password resets and campaigns run off one contact database, one reputation and one bill. For a small team without a dedicated ops person, that is a genuine reduction in surface area.
A v3 REST API, 7 official SDKs, plain api-key header authentication and an official MCP server. Among marketing platforms only Brevo and Klaviyo ship official agent tooling, and Brevo is the cheaper of the two by a wide margin.
Who should look elsewhere
At least 17 of 157 reviewers describe suspension, blocking or abrupt verification, mostly in the first days and mostly in five-star reviews. If a launch date depends on your first campaign going out on schedule, do not let account verification be on the critical path.
At least 28 reviewers name the depth ceiling on advanced features, templates and customization. Brevo does breadth. For serious automation go to Klaviyo or ActiveCampaign; for design go to Flodesk; for pure transactional go to Postmark.
88.3 percent in the most recent independent round is the lowest of the tested group, against 91.7 for Constant Contact and 94.2 for ActiveCampaign. The corpus is happier than the panel, but plan against the measured number, not the reviews.
At least 21 reviewers name the complexity, and a recurring specific one is that contact and recipient counts are confusing. On a platform that meters sends, misreading who is in a send costs money. MailerLite is one product instead of eight and easier to hand over.
Third-party validation
All figures read on August 27, 2026.
| Source | Score | Reviews |
| G2 | 4.5 / 5 | 2,625 |
| Capterra | 4.6 / 5 | 3,512 |
| Trustpilot | N/A | Not retrieved |
The gap between G2 and Capterra is 0.1, far under the 1.5 point threshold at which we stop and reconcile a divergence, and the combined sample of 6,137 reviews is the largest we have worked with after Constant Contact. A high score on a large sample is worth more than a high score on a small one, and Brevo’s is both.
One caution on searching for this product yourself. G2 lists more than one entity containing the word Brevo, and the figures above are from Brevo Marketing Platform, which is the product this review covers. A similarly named unrelated listing carries no reviews at all. If you are comparing scores from a different article, check which listing it read.
We are not running the corpus-mean integrity check on this profile. Our harvest covers roughly 157 distinct reviews out of 3,512 declared, about 4 percent, and a partial harvest at that ratio cannot reproduce a lifetime average. The thematic counts stand on their own; the distribution does not.
Top 3 alternatives
- MailerLite is the answer if the breadth is the problem. One product instead of eight, the best support sub-score in the category at 4.8, and a much gentler first week. We rate it 7.4 against Brevo’s 7.7.
- Postmark is the answer if transactional is really what you came for. It does one job, its inbox placement is measured and high, and it ships a 24-tool official MCP server. From $15/mo, and we rate it 7.8.
- Mailchimp is the comparison prospects actually run, at 210 searches a month for brevo vs mailchimp. Mailchimp has more integrations and better brand recognition. Brevo is cheaper, has SMTP, and does not bill you for contacts you never mail.

Frequently asked questions
Is Brevo free? Yes, permanently. The free tier allows 300 emails a day with unlimited contacts and SMTP included, which is unusual: most free tiers cap the list, not the sending. It is a genuine working tier rather than a trial, and reviewers run small businesses on it.
How much does Brevo cost? Paid plans start in single digits per month and scale on emails sent, not contacts stored. That is the key difference from most competitors and it makes Brevo structurally cheaper for any large list that is mailed occasionally. Two things to check before committing: purchased credits do not carry over, and extra users are charged separately. Full ladder on our pricing tab.
What is Brevo? A French all-in-one marketing platform founded in 2007, known as Sendinblue until May 2023. It covers email campaigns, transactional sending over SMTP, SMS, WhatsApp, a CRM and chat from one contact database. Full background on the Brevo hub.
Does Brevo have SMTP? Yes, at smtp-relay.brevo.com, and the legacy smtp-relay.sendinblue.com hostname still resolves as an alias. Brevo is the only platform in this comparison group that publishes an SMTP relay at all. Ports and key management on our SMTP settings tab.
Is Brevo better than Mailchimp? On price and scope, clearly: Brevo bills sends rather than stored contacts, includes SMTP and transactional, and ships an official MCP server, none of which Mailchimp does. Mailchimp has more integrations and a more polished editor. Our scores: Brevo 7.7, Mailchimp 6.3.
Is Brevo good? Yes, on a large sample: 4.6/5 on Capterra across 3,512 reviews and 4.5/5 on G2 across 2,625. We rate it 7.7/10, the highest of any marketing platform we have profiled. The one thing the star ratings hide is the account-protection system, described by 17 of the 157 recent reviews we read.
What are the best Brevo alternatives? MailerLite for simplicity, Postmark for pure transactional, Mailchimp for integration breadth. Full list on the alternatives tab.
Is Sendinblue the same as Brevo? Yes. Sendinblue rebranded to Brevo in May 2023. The old name still draws 6,600 US searches a month, seventeen times the volume of brevo review, so a great deal of the advice you will find online predates the change and may quote different pricing. The legacy SMTP hostname still resolves.
