Mail10s is a temporary email service designed to help people receive messages without sharing their personal email address or creating an account. Users can generate disposable addresses in seconds and view incoming messages in an inbox, with automatic extraction of OTP codes from supported services including Facebook, Google, and Instagram. The service highlights speed, privacy, and convenience, and says temporary email addresses are automatically deleted after they expire.

Mail10s also offers tools for developers and other users who want to integrate temporary email into their workflows. Its RESTful API supports generating or renting email addresses, listing available domains, reading inbox messages, extracting OTP codes, and waiting for codes through long polling. Real-time updates are available through Server-Sent Events, and the service supports multiple domains for different needs. The site provides API documentation, pricing information, and account access, alongside privacy and terms pages. With instant address creation, inbox access, and OTP handling in one service, Mail10s presents itself as a practical option for temporary email use and integration.
