The Allegrow Email Validation API provides real-time and asynchronous email validation services to help improve deliverability and reduce bounce rates.

The API offers three validation options:

Synchronous validation (/v1/email/validate) - Receive the validation result in the same call
Asynchronous validation (/v1/email/validate-async) - Submit validation requests and receive results via webhook
Bulk CSV validation (/v1/email/validate-file) - Upload a CSV file and validate all emails in bulk

The first step is to generate your API Key needed for all calls to Allegrow API.
Please follow the Authentication Guide.
