Email Validation for Brevo

Why Validate Emails for Brevo?

Brevo's free tier limits contact counts, and paid plans charge per contact. Invalid emails eat into your quota and reduce campaign performance. Validation helps you maximize your allowed contacts and maintain strong deliverability.

Benefits

• ✓ Maximize your Brevo contact quota with a clean list
• ✓ Improve email open and click rates
• ✓ Reduce spam complaints from bounced emails
• ✓ Stay within free tier limits longer

How to Validate Brevo Emails

1. Step 1: Export your Brevo contact lists from the Contacts section as CSV
2. Step 2: Upload to an email validation service for bulk verification
3. Step 3: Remove or segment invalid contacts before your next campaign
4. Step 4: Set up double opt-in for new subscribers to prevent future invalid signups

API Integration

Integrate email validation directly into your Brevo workflow:

// Brevo API - Manage contacts after validation
const SibApiV3Sdk = require("sib-api-v3-sdk");

const client = SibApiV3Sdk.ApiClient.instance;
const apiKey = client.authentications["api-key"];
apiKey.apiKey = process.env.BREVO_API_KEY;

const apiInstance = new SibApiV3Sdk.ContactsApi();

// Delete invalid contacts from Brevo
for (const email of invalidEmails) {
  try {
    await apiInstance.deleteContact(email);
  } catch (err) {
    console.log(`Contact ${email} not found`);
  }
}

// Update valid contacts with custom attribute
await apiInstance.updateContact(email, {
  attributes: { VALIDATION_STATUS: "verified" },
});
