Unosend

Send transactional email through an API or SMTP with delivery tracking

Meet Unosend

Unosend is an email delivery service for product teams that need to send transactional messages such as verification codes, receipts, and account alerts. Developers can integrate through a REST API or standard SMTP, configure sending domains, and separate different message streams within one workspace.

The service provides delivery logs, bounce handling, suppression lists, event webhooks, and reporting on sends, opens, and clicks. A template editor supports visual composition and HTML with reusable variables. Unosend is useful for teams that want application email infrastructure alongside tools to inspect delivery problems, manage sender configuration, and maintain branded messages across different parts of a product.
