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
Single-email responses (sync, polling, and async webhook) include the headline result.status alongside a domain object (with name, mxProvider, mxRecords, and isCatchAll) and a mailbox object (with isRoleAccount) — signals you can use for downstream decisions. See Validation Statuses for the full field reference.
The first step is to generate your API Key needed for all calls to Allegrow API.
