# UniOne

> UniOne is an email delivery platform for transactional and bulk email. It provides a high-throughput Web API and SMTP relay for sending, tracking, and validating email at scale, with EU and US datacenters.

Use UniOne to send application-generated and bulk email, including signup confirmations, password resets, receipts, notifications, and marketing messages.

UniOne provides two primary integration paths:

- Web API is preferred for new integrations and provides higher throughput and broader product coverage.
- SMTP API provides a simpler integration when SMTP compatibility is required.
