Brevo (Sendinblue) Integration
Brevo (formerly known as Sendinblue) has become one of the most popular all-in-one marketing platforms out there. From email campaigns to SMS marketing to CRM, it's a powerhouse for businesses of all sizes.
But here's the thing - even the best email platform can't help you if you're sending to invalid addresses. That's where Valid Email Checker comes in. Connect your Brevo account and verify your contact lists without the tedious export-import dance.
What You Can Do
With the Brevo integration, you can:
- Import contacts directly from your Brevo lists
- Verify email addresses without downloading or uploading files
- Automatically clean lists by removing or unsubscribing bad emails
- Protect your sender score by catching invalid emails before they bounce
- Connect multiple Brevo accounts if you manage several
Before You Start
Make sure you have everything ready:
| Requirement | Details |
|---|---|
| Brevo account | Free or paid plan |
| API key | Generated from SMTP & API settings |
| Valid Email Checker credits | Enough to cover your list size |
| Contacts to verify | At least one list in your Brevo account |
If you're wondering about the name - Sendinblue rebranded to Brevo in 2023. The platform is the same, just with a fresh look and name. You might still see "Sendinblue" in some places within the interface, and that's perfectly normal.
Finding Your Brevo API Key
Brevo uses API keys for secure integration. Here's how to create one:
Step 1: Access SMTP & API Settings
- Log in to your Brevo account
- Click your account name in the top-right corner
- Select Settings from the dropdown menu
- In the left sidebar under Organization settings, click SMTP & API
- Click the API keys & MCP tab
Step 2: Generate a New API Key
- Click Generate a new API key button (top right)
- Enter a name for your key (e.g., "Valid Email Checker Integration")
- Click Generate
Brevo shows your API key only once when you create it. Copy it right away and store it somewhere safe. If you lose it, you'll need to generate a new one.
Connecting Your Brevo Account
Now let's connect Brevo to Valid Email Checker.
Step 1: Open the Connection Modal
You have two ways to start:
Option A: From Integrations page
- Go to Integrations in the sidebar
- Find Sendinblue(Brevo) in the Available Integrations
- Click on it to open the connection modal
Option B: From Bulk Upload page
- Go to Bulk Upload
- Click Connect Email Platform
- Select Sendinblue (Brevo) from the list
Step 2: Enter Your Credentials
In the connection modal:
- Connection Name (optional): Give this connection a friendly name like "Main Brevo Account" or "Marketing Team"
- Brevo API Key: Paste the API key you just created
- Click Connect Account
The modal includes a helpful "Where do I find my API key?" link showing the path: Settings → SMTP & API → API keys & MCP → Generate a new API key
Step 3: Connection Success
Once connected, Valid Email Checker syncs with your Brevo account and fetches your available lists.
Verifying Your Brevo Lists
After connecting, you can verify your contacts.
Step 1: Select a List
You'll see all your Brevo lists with the number of contacts in parentheses. Use the search bar to find specific lists if you have many.
Select the list you want to verify.
Step 2: Choose Your Verification Mode
You have two options:
Option 1: Verify Only
Select Verify only to:
- Import and verify all emails
- See detailed results for each contact
- Make your own decisions about what to do with each email type
- Download results and review before taking action
This is perfect if you want to understand your list health before making changes.
Option 2: Clean List Automatically
Select Clean list automatically for hands-free cleaning:
Configure what happens to each email type:
| Email Type | Options | Default |
|---|---|---|
| Invalid | Keep / Unsubscribe / Delete | Unsubscribe |
| Disposable | Keep / Unsubscribe / Delete | Delete |
| Catch-all | Keep / Unsubscribe / Delete | Keep |
| Unknown | Keep / Unsubscribe / Delete | Keep |
| Risky | Keep / Unsubscribe / Delete | Keep |
When you choose "Delete," contacts are permanently removed from Brevo. This cannot be undone. If you're unsure, use "Unsubscribe" instead - it preserves the contact but prevents them from receiving emails.
Step 3: Configure Additional Options
Remove Duplicates: Toggle on (recommended) to automatically remove duplicate email addresses before verification. This saves credits and ensures accurate counts.
Step 4: Review and Import
Check the credit summary at the bottom:
- Credits needed: Estimated credits for this verification
- Available credits: Your current balance
Click Import List to start the verification.
Monitoring Your Verification
After clicking Import List, you're redirected to the Uploads & Results page.

Managing Your Brevo Connection
Viewing Connected Accounts
Go to Integrations in the sidebar to see all your connected platforms.
Your Brevo connection shows:
- Provider: Sendinblue (Brevo) with logo
- Connection Name: The name you gave it
- Status: Active (green badge)

When to Sync
Use Sync Now when:

Syncing refreshes the list data from Brevo but doesn't re-verify anything.

- Select Sendinblue (Brevo)
- You'll see your existing connections listed under "Your Connections"
- Click + Add Another Account
- Enter the new API key and a unique name
- Click Connect Account
Managing Multiple Connections
Each Brevo connection appears separately in your Integrations list. Use clear names to tell them apart:
- "Brevo - Main Account"
- "Brevo - Client ABC"
- "Brevo - Newsletter"
Each connection needs a unique name. If you try to use the same name twice, you'll be prompted to choose a different one.
