Brevo
FreemiumThe all-in-one email and CRM platform for growing businesses.
Published 27 September 2026
Scores
Popularity3/5
One of the largest all-in-one email platforms by customer count, especially recognized among small and mid-sized businesses and marketing teams under its former name Sendinblue, though it has less name recognition among developers specifically than API-first competitors.
Learning Curve3/5
The transactional API and SMTP relay are quick to wire up on their own, but the platform bundles marketing automation, a CRM, and multi-channel messaging, and reviewers note the automation workflow builder takes more effort to configure well than the core send-an-email path.
Flexibility4/5
Covers transactional API sending, SMTP relay, marketing campaigns, landing pages, and SMS/WhatsApp messaging from one contact database, giving it a broader feature surface than API-only competitors aimed purely at developers.
Performance3/5
Handles standard transactional and campaign volume reliably for most senders, but user reports of intermittent dashboard and login outages and inconsistent deliverability on some sending patterns keep it a step behind specialist high-deliverability competitors.
Portability2/5
A proprietary SaaS platform with no self-hosted option; the standard SMTP relay offers an easier migration path than API-only competitors, but marketing automation, CRM data, and campaign history are tied to the platform.
About Brevo
Brevo, formerly known as Sendinblue, is an all-in-one customer communication platform built around email, combining a developer-facing transactional API with marketing automation, SMS and WhatsApp messaging, and a built-in CRM. Founded in Paris in 2012 and rebranded in 2023, it has grown into a publicly traded company serving hundreds of thousands of businesses, most of them small and mid-sized teams rather than large enterprises.
On the developer side, Brevo offers a REST API with official SDKs for PHP, Python, Node.js, Ruby, Go, Java, and C#, alongside a standard SMTP relay for teams that prefer not to touch the API directly. Transactional sending includes template management, outbound webhooks for delivery events, and unlimited log retention even on the free plan. Contact and event data from API calls, marketing campaigns, and SMS activity are unified in a single contact profile through Brevo's built-in CRM, rather than being siloed by channel.
The marketing side adds a drag-and-drop campaign builder, landing pages, segmentation, and automation workflows, positioning Brevo as a single platform for teams that want transactional sending and marketing outreach under one account rather than stitched together from separate tools. Pricing is largely volume-based on the transactional side and scales with both email volume and contact count on marketing plans, with a permanent free tier that requires no credit card.

Pros
- Permanent free plan (300 emails/day, no credit card) rather than a time-limited trial
- Combines transactional API sending, marketing campaigns, and a free-access CRM in one account

Cons

Resend is the minimal, developer-first alternative to Brevo for teams that only need transactional sending with React Email templates, without Brevo's marketing automation, CRM, or multi-channel messaging.
SendGrid is the higher-volume, enterprise-oriented alternative to Brevo, with a longer deliverability track record and dedicated-IP options for teams that outgrow Brevo's SMB-focused pricing and features.
