Set up Brevo

Brevo works well when you already manage your sender identities there — connect Mailrith with an API key and let Brevo handle delivery while Mailrith manages campaigns and audience targeting.

The Email Delivery Connections page lists every connected provider. From here you can add a new connection, send a test email, view webhook endpoints, and assign connections to workspaces.

Before you start

Before connecting Brevo to Mailrith, confirm the following in your Brevo account:

  • Your sender identity is active. In Brevo, go to Senders & IPs → Senders and confirm the email address or domain you plan to send from is verified and active. Unverified senders will cause delivery failures.
  • Create an API key. In Brevo, go to Account → SMTP & API → API Keys and generate a new API key. Make sure it has the permission level needed for transactional email sending.

Mailrith fields

When creating a Brevo connection in Mailrith, fill in the following fields:

  • API Key: the Brevo API key with transactional send permission.
  • From name: the display name that recipients see in their inbox — for example, "Acme Newsletter".
  • From email: the email address in the From field. Must match a sender identity verified in Brevo.

After saving, open View webhooks on the Brevo connection to get the endpoint URL for configuring event tracking in Brevo.

Brevo setup

  1. In Brevo, go to Account → SMTP & API → API Keys and create a new API key. Copy the value.
  2. In Mailrith, create a new connection and select Brevo. Enter the API key, From name, and From email.
  3. Save the connection.
  4. Click Send test email to verify the API key is correct and that the From email is a valid active sender in Brevo.

If the test email fails with a sender-not-verified error, go back to Brevo and confirm the sender address you entered is fully verified under Senders & IPs.

Webhooks and test send

Brevo delivers transactional email events — including bounces and spam reports — to a webhook endpoint. To configure it:

  1. In Mailrith, open the connection row and click View webhooks. Copy the webhook URL.
  2. In Brevo, go to Transactional → Settings → Webhooks and add a new webhook.
  3. Paste the Mailrith URL and enable at minimum the Hard bounce and Spam event types.
  4. Save. Brevo will begin forwarding these events to Mailrith, which uses them to update subscriber statuses automatically.

Once the webhook is configured, send a Mailrith test email to confirm the complete setup is working correctly. Check that the email arrives in the target inbox and that the connection appears as active in the Mailrith connections list.
