Tmailor is a temporary email service designed to help people receive messages without sharing their personal email address. A disposable inbox is created automatically when visitors open the service, with no account, password, or personal information required. Users can copy the address, use it for sign-ups, downloads, or verification messages, and view incoming mail in a real-time web mailbox.

The service includes tools for generating or changing email addresses, selecting available domains, and accessing an inbox across devices with a QR code. Users can review message details and attachments, mark messages as favorites, and revisit previously used addresses through email history. Tmailor is intended for short-term uses such as one-time verification and trials, rather than as a replacement for a permanent mailbox or for sensitive communications.

Tmailor offers a free plan and paid monthly and yearly plans. Depending on the plan, features include different limits for custom domains, email history, and favorite messages, as well as no ads and attachment viewing.
