What Mail.tm is
Mail.tm lets users create temporary email accounts and receive messages through a REST API. The documented flow is to request an available domain, create an account, use its address for an email confirmation, and retrieve messages. Messages can be fetched through the API or delivered as real-time Server-Sent Events through Mercure.
The API supports listing, reading, marking as read, and deleting messages, as well as accessing attachments. Most requests need a bearer token; account creation and domain listing are exceptions, and no API key is required. The free API access plan costs nothing, has no signup or paid tiers, and allows 8 queries per second per IP address. Mail.tm lists community-built libraries for .NET, Dart, Go, Java, JavaScript, PHP, Python, Rust, and Swift.
The API terms prohibit illegal activity, resale of a paid product wrapping the API, and proxying or mirroring it; visible attribution to Mail.tm is required. Questions and suggestions can be sent to [email protected]. Mail.tm says its technology stack includes API-Platform, Mercure, Nuxt.js, Haraka, Caddy, MongoDB, Node.js, and CentOS.
