MTN Verify
An email and identity verification API for keeping outreach lists clean and deliverable.
The brief
Sending to unverified addresses burns sender reputation and wastes spend. The product needed a fast, reliable verification API that other systems could depend on at volume.
What was built
- A verification engine that validates email and identity signals.
- A public API designed for reliability under load — idempotency, rate limits, and clean failure handling.
- Webhook delivery so downstream systems stay in sync.
What it demonstrates
Production API craft: the reliability, versioning, and failure-handling discipline that a service other companies build on top of actually requires.
