## What Brevo is great at. Where Bird is different.

### What Brevo is great at

- An all-in-one suite. Marketing campaigns, CRM and sales, automation, SMS, WhatsApp, and live chat on one self-serve account. If you want a single tool for the whole funnel, Brevo covers it.
- One contact database behind every channel. The same contact list and segments drive campaigns, automation, chat, and transactional mail, so there is no syncing between a marketing tool and a sending API.
- A low entry cost. A generous free tier and cheap volume-slider pricing up to around 100K a month make it easy to start.
- Pay-as-you-go email credits. Credits that do not expire, useful for irregular or seasonal sending.

### Where Bird is different

- Built on SparkPost. Bird’s email runs on SparkPost, the deliverability platform Bird acquired in 2021. It carries about 40% of the world’s commercial email, a depth of transactional deliverability that an all-in-one marketing suite does not focus on.
- A developer-first API. Errors as values with .safe(), an idempotency key reused across retries, scoped API keys, and a hosted MCP server. Brevo’s API is capable too; the difference is the error-as-value result shape.
- Dedicated IPs as standard. Dedicated IPs and pools with automated warm-up for senders who need their own reputation, rather than an annual add-on gated to higher plans.
- Comms infrastructure, not a marketing tool. Email, SMS, and voice as one programmable API for product and engineering teams, rather than a campaign-and-CRM dashboard.

## Capability by capability.

Brevo wins as an all-in-one suite (marketing, CRM, SMS, WhatsApp, and chat) with a low entry price. Bird wins on transactional deliverability depth on the SparkPost network and a developer-first API, and both offer a customer SMTP relay. They suit different buyers.

| Capability | Bird | Brevo | Who wins |
| --- | --- | --- | --- |
| Transactional send API | HTTP API (POST /v1/email/messages) with an error-as-value SDK. | HTTP API (POST /v3/smtp/email) with an api-key header. | Even |
| SMTP relay | Customer-facing relay at eu1 and us1.smtp.bird.com. Implicit TLS on 465, STARTTLS on 587 and 2525, authenticated with a normal API key. | Customer-facing SMTP relay at smtp-relay.brevo.com. | Even |
| Marketing, CRM, and chat suite | Focused on programmable comms (email, SMS, voice), not campaigns or CRM. | Campaigns, CRM and sales, automation, and live chat on one account. | Brevo |
| Idempotency on send | Idempotency-Key header, reused across retries. | Idempotency-Key header on transactional and batch sends. | Even |
| Deliverability heritage | Runs on SparkPost (acquired 2021): roughly 40% of the world’s commercial email. | Strong for SMB marketing volume; not a dedicated transactional-scale platform. | Bird |
| Dedicated IPs | Dedicated IPs and pools with automated warm-up. | Dedicated IP is an annual add-on on Professional; included on Enterprise. | Bird |
| Developer experience | Error-as-value SDK, scoped API keys, and a hosted MCP server. | Capable SDKs and an official MCP server; no error-as-value pattern. | Bird |
| SPF, DKIM, DMARC | SPF, DKIM, and DMARC signed for verified domains, with optional BIMI. | SPF, DKIM, and DMARC supported, with BIMI. | Even |
| Event webhooks | Twelve event types with Standard Webhooks signing. | Fifteen transactional event types via webhooks. | Even |
| Channels beyond email | Email, SMS, and voice as one programmable API. | Email, SMS, WhatsApp, push, and chat, oriented around the marketing suite. | Even |

## One send, two API styles.

Sending one HTML email. Brevo takes a config object on a unified client. Bird is a bearer-token call that returns a typed result. The fields map directly.

**Brevo** · send.ts

```typescript
import { BrevoClient } from "@getbrevo/brevo";

const brevo = new BrevoClient({ apiKey: process.env.BREVO_API_KEY! });

await brevo.transactionalEmails.sendTransacEmail({
  sender:      { email: "onboarding@yourdomain.com", name: "Acme" },
  to:          [{ email: "customer@example.com" }],
  subject:     "Your March invoice",
  htmlContent: "<p>Attached.</p>",
});
```

**Bird** · send.ts

```typescript
import { BirdClient } from "@messagebird/sdk";

const bird = new BirdClient({ apiKey: process.env.BIRD_API_KEY! });

const { data, error } = await bird.email
  .send({
    from:    { email: "onboarding@yourdomain.com", name: "Acme" },
    to:      ["customer@example.com"],
    subject: "Your March invoice",
    html:    "<p>Attached.</p>",
  })
  .safe();

if (error) console.error(error.message);
else console.log(data.id);
```

## Pricing at a glance

Brevo meters campaigns and transactional email together on its all-in-one plans, so the figures are its monthly plan price at each volume.

| Emails / month | Bird | Brevo |
| --- | --- | --- |
| 50,000 | $20/mo (Starter) | $68/mo (Starter) |
| 250,000 | $170/mo (Premier) | $249/mo (Professional) |
| 1,000,000 | $525/mo (Premier) | $999/mo (Professional) |

## Switching cost: Low for transactional.

Moving the transactional side is straightforward: domain authentication, a blocklist or suppression list, and event webhooks map across, and the send fields line up directly.

If you also use Brevo for marketing campaigns and CRM, those stay where they are. Bird replaces the transactional and programmable-comms layer, not the marketing suite. The migration guide covers domain auth and event mapping.

## Bird vs Brevo: common questions

### Should I pick Bird or Brevo?

It depends on the job. If you want one tool for marketing campaigns, CRM, and email, Brevo’s all-in-one suite is a strong fit. If you need serious transactional deliverability and a developer-first API for email, SMS, and voice, Bird is built for that, running on the SparkPost network that carries about 40% of the world’s commercial email.

### Does Bird replace Brevo entirely?

Not the marketing and CRM side. Bird replaces the transactional email and programmable-comms layer. Teams that rely on Brevo for campaigns and sales would keep those and use Bird for transactional sending.

### Does Bird offer an SMTP relay like Brevo?

Yes. Point your client at eu1.smtp.bird.com or us1.smtp.bird.com, on port 465 for implicit TLS or 587 and 2525 for STARTTLS. The username is bird and the password is a normal API key with the emails scope, so there is no separate SMTP credential. Mail submitted over SMTP goes through the same pipeline as the API, with the same domain verification, IP pools, DKIM signing, suppressions, tracking, and events.

### How does Bird’s deliverability compare to Brevo’s?

Bird is purpose-built for transactional deliverability on SparkPost, with dedicated IPs, automated warm-up, and full authentication. Brevo handles marketing and transactional volume well for SMBs but is not a dedicated transactional-scale platform.
