3

Choose Your Plan

Select from subscription plans or use pay-as-you-go credits based on your needs.

​
Make Your First Request

Once you have your API key, you can start validating emails immediately. Here’s how to validate a single email address: 
curl -X POST https://base.sanitizeemail.com/v1/api/email-validation/ \
  -H "Content-Type: application/json" \
  -H "X-API-KEY: YOUR_API_KEY" \
  -d '{
    "emails": ["user@example.com"],
    "options": {
      "validate_smtp": true
    },
    "file_tag": "quickstart-test"
  }'

​
Understanding the Response

The API will return detailed validation results for each email: 
{
  "results": [
    {
      "email": "user@example.com",
      "status": "valid",
      "normalized_email": "user@example.com",
      "is_disposable": false,
      "is_role_account": false,
      "reason": {
        "format": {
          "status": "pass",
          "reason": "Valid email format"
        },
        "dns": {
          "status": "pass",
          "reason": "Domain exists"
        },
        "mx": {
          "status": "pass",
          "reason": "MX records found"
        },
        "smtp": {
          "status": "pass",
          "reason": "SMTP server responds"
        }
      },
      "mx_records": ["mx1.example.com", "mx2.example.com"]
    }
  ],
  "stats": {
    "total": 1,
    "valid": 1,
    "invalid": 0,
    "disposable": 0,
    "role_accounts": 0
  },
  "credits_used": 1,
  "remaining_processing": 0,
  "batch_size": 1
}

​
Bulk Email Validation

You can validate multiple emails in a single request for efficient bulk processing: 
{
  "emails": ["user1@example.com", "user2@domain.com", "test@company.org"],
  "options": {
    "validate_smtp": true
  },
  "file_tag": "bulk-validation"
}

​
Validation Options

Set validate_smtp: true to perform real-time SMTP checks. This provides the most accurate validation but takes longer.
Use file_tag to organize and identify your validation batches for easier tracking.
The API has rate limits to ensure optimal performance. Check the response headers for rate limit information.

​
Error Handling

Always check for errors in your API responses:
  • 400: Bad request - Invalid payload format
  • 401: Unauthorized - Missing or invalid API key
  • 403: Forbidden - API key is inactive
  • 429: Rate limit exceeded
Keep your API key secure and never expose it in client-side code. Store it as an environment variable or in a secure configuration file.
