mail.tm
Spin up throwaway inboxes over a JSON:LD REST API
mail.tm is a temporary-email service with a clean REST API for creating disposable mailboxes and reading messages. The /domains endpoint lists which mail domains are currently available to register against, and it needs no authentication. Responses come back as Hydra/JSON-LD collections.
