What is an email API?

An email API (Application Programming Interface) allows you to send, receive, and manage emails programmatically from your application. Instead of using an email client, you make HTTP requests to the API endpoint, which handles delivery, tracking, and infrastructure.

Is Brevo's email API free?

Yes. Brevo offers a free plan with 300 emails per day with no time limit and no credit card required. The free plan includes full API access, webhooks, email tracking, templates, and support. If you need to send more, paid plans start at $9/month.

How do I get started with Brevo's email API?

Sign up for a free account, verify your sending domain, generate an API key, and install the SDK for your programming language. You can send your first email in under 10 minutes.

Which programming languages does Brevo support?

Brevo provides official SDKs for PHP, Python, Node.js, Ruby, Go, Java, and C#. You can also use the REST API with any language that supports HTTP requests, including cURL for testing.

What's the difference between the email API and SMTP relay?

Both send emails, but they work differently. The REST API uses JSON over HTTPS and supports advanced features like webhooks, templates, and scheduled sends. It's the recommended method for modern applications. SMTP relay uses the traditional SMTP protocol (port 587) and works with legacy systems or applications that only support SMTP. It doesn't support templates or webhooks.

Does Brevo offer webhooks?

Yes. Brevo sends real-time webhook notifications for all email events: delivered, opened, clicked, bounced, spam complaints, and unsubscribed. Configure webhook URLs in your dashboard to receive HTTP POST requests whenever these events occur. You can set up to 40 webhook endpoints per account.

Can I use Brevo for both transactional and marketing emails?

Yes. Brevo handles both transactional emails (password resets, order confirmations) and marketing emails (newsletters, campaigns) in one platform, along with CRM and sales tools. Transactional and marketing emails are sent through separate streams to maintain optimal deliverability for time-sensitive messages.

What are the API rate limits?

Free plan: 300 emails per day, 1,000 requests per second Paid plans: No daily limit, 1,000-6,000 requests per second depending on plan If you exceed the rate limit, the API returns a 429 status code.

How does Brevo ensure email deliverability?

Brevo maintains high deliverability through automatic SPF, DKIM, and DMARC configuration, real-time reputation monitoring, dedicated IP options on higher plans, and email validation API to verify addresses before sending. Average inbox placement rate is 99% across major providers including Gmail, Outlook, and Yahoo.

How long are email logs stored?

Brevo stores transactional email logs without a time limit for standard-volume accounts. For accounts exceeding 10 million events, logs are retained for up to 24 months by default, with extended options available on Enterprise plans.

Is Brevo's email API GDPR compliant?

Yes. As a European company, Brevo hosts your data in France and Germany. We are GDPR compliant and ISO 27001:2022 certified, ensuring maximum service availability and security for your transactional emails.
