​

What you will build

Create an n8n workflow using the Bolt Route - Email Validation & Verification node to verify single emails or submit bulk tasks.

​

Step 1: Create your Bolt Route API key

1. Create an account or log in to Bolt Route.
2. Open app.boltroute.ai/api.
3. Click New key.
4. In the Generate API key dialog, select n8n to tag usage. Keys are universal, so the selection only tags usage.
5. Enter a key name, then click Create key.
6. Copy the key now. It is shown only once.

​

Step 2: Install the community node

1. In n8n, go to Settings -> Community Nodes.
2. Click Install and enter n8n-nodes-email-verifier.
3. Restart n8n if the node does not appear in the editor.
4. If you are already building a workflow, search for Bolt Route - Email Validation & Verification in the node picker. If it does not appear, install it from Community Nodes.

​

Step 3: Create credentials

1. Open Credentials and click Create New.
2. Search for Bolt Route API.
3. Paste your API key.
4. Confirm the Base URL is https://api.boltroute.ai/api/v1 unless you use a custom endpoint.
5. Click Test Connection and save.

​

Step 4: Realtime verification in n8n

1. Create a new workflow and add your trigger node.
2. Add Bolt Route - Email Validation & Verification.
3. Set Resource to Email Verification and Operation to Verify Single Email.
4. Map Email Address from your trigger.
5. Execute the node. Use status, is_disposable, and is_role_based in downstream steps.

​

Step 5: Batch verification in n8n

1. Add Bolt Route - Email Validation & Verification.
2. Set Resource to Email Verification and Operation to Create Bulk Task.
3. Map Emails to a list of addresses (one per item, up to 10,000).
4. Optionally set Webhook URL if you have a receiving workflow.
5. Execute the node. The response includes a task id.

​

Step 6: Track results

1. Add another Bolt Route - Email Validation & Verification node.
2. Choose Get Task to check progress_percent or Download Task Results to fetch the CSV/XLSX.
