It shares the same 600-free-calls-per-month tier as Cloudmersive's other validation products in this catalog.

mail.tm

mail.tm issues disposable inboxes on shared domains and exposes a Hydra/JSON-LD REST API to create accounts, fetch a bearer token, and read incoming messages, all without any signup fee. It's the fully free, actively maintained sibling of mail.gw.
