Does the Email Validation API detect disposable email addresses?

Yes. It flags disposable, temporary and role-based addresses (like admin@ or info@) so you can route them to additional checks or reject them at signup.

Is email validation DPDP-compliant?

Yes. Every call captures a consent artifact and is written to a tamper-evident audit log, consistent with DPDP data-minimisation and purpose-limitation principles.

Overview

What the Email Validation API Does

FinHub's Email Validation API checks syntax, MX/domain health and inbox-level deliverability in a single call, so onboarding forms and KYC workflows reject dead or malformed addresses before they cost you a failed OTP or a lost lead. Every check runs against a consent artifact and writes to a tamper-evident audit log, in line with DPDP data-handling requirements.

Inputs

Email address
Consent artifact ID
Check depth (syntax / domain / inbox)

Returns

Syntax validity
Domain & MX health
Inbox existence (deliverability)
Disposable/role-account flag
Risk score
