Use Case

Use batch email verification to clean large lists before a campaign, CRM import, or migration. This protects deliverability and keeps your lists focused on reachable inboxes.

​
Where Verification Fits

Workflow at a glance:

1. Export

Pull the list from your CRM, ESP, or database.

2. Verify

Create a batch task with up to 10,000 emails.

3. Segment

Split results by status and risk flags.

4. Import

Load clean segments back into your ESP or CRM.
  1. Export the list of emails from your CRM or database.
  2. Create a batch verification task with up to 10,000 emails.
  3. Poll the task status or wait for a webhook notification.
  4. Download results and segment the list by status and risk flags.
  5. Import only acceptable addresses into your next campaign.

Minimal API Example

curl -X POST \
  'https://api.boltroute.ai/api/v1/tasks' \
  -H 'Content-Type: application/json' \
  -d '{"emails":["user1@example.com","user2@example.com"]}'

{
  "id": "550e8400-e29b-41d4-a716-446655440000",
  "email_count": 2,
  "domain_count": 1
}

​
Decision Rules

Common batch segmentation rules:
  • Keep valid addresses for campaigns.
  • Suppress invalid_syntax and invalid.
  • Review catchall and unknown before sending.
  • Suppress is_disposable for most lifecycle or paid campaigns.

​
Operational Notes

If your list is large, use a webhook so your pipeline updates automatically when the task finishes.
