Brevo (formerly Sendinblue) is the email platform I recommend when a business has a big list it does not mail very often. The reason is the pricing model: Brevo charges for emails sent, not contacts stored, which inverts the math that makes most tools expensive. The free tier underlines the point with 100,000 contacts and 300 emails a day, automation and segmentation included, which is generous enough to be genuinely unusual in this category.
What it does best
Serving large, infrequently-mailed lists cheaply, and doing transactional email well alongside marketing. Because you pay by send volume, importing tens of thousands of contacts costs nothing until you actually email them, so a 20,000-name list you newsletter once a month lands in a far cheaper bracket here than on a contact-count tool. On top of that, Brevo bundles email, SMS, and WhatsApp messaging plus solid transactional email in every plan, so it covers both the campaign side and the system-generated receipts and notifications most platforms split into separate products.
Pricing and what you actually get
The free plan gives 300 emails a day and 100,000 stored contacts with no card required and no expiry. Paid Starter plans begin at $9/month for 5,000 emails and scale up through higher send volumes, with Standard tiers adding more automation and a Professional plan at $499/month for advanced needs. The catch to budget for is branding: the lower plans stamp Brevo on your emails by default, and removing it is a paid add-on, which feels stingy at the entry price.
Where it falls short
The branding add-on on cheaper plans is the most immediate annoyance, since paying to remove someone else's logo from your own emails grates. The AI feature set is also thinner and less front-and-center than Klaviyo or ActiveCampaign, so if AI-driven content and predictive sending are central to your strategy, Brevo will feel behind. And the jump from the lower tiers to the $499/month Professional plan is a large step, which can leave growing senders stuck between an outgrown small plan and an expensive next one.
Who it's for
Small businesses and creators getting started with email, and anyone sitting on a large list they mail occasionally rather than constantly. The free tier makes it a natural first email tool, and the send-based pricing rewards exactly the lists that punish contact-based competitors. If your strategy leans heavily on AI features and sophisticated lifecycle automation, Klaviyo or ActiveCampaign are the stronger fit despite costing more.
Getting the most out of it
Before you assume a contact-based tool is cheaper, model your actual monthly send volume against Brevo's email tiers, because for large-but-quiet lists the gap is often large in Brevo's favor. Lean on the free tier to load your full audience at no cost and prove your workflow before paying, and use the included transactional email so your receipts and notifications run through the same deliverability infrastructure as your campaigns instead of a separate service.
