The service is built and operated by FreeCustom.Email and also offers a CLI tool and a developer API for programmatic access.

Who is it for?
FreeCustom.Email is designed for developers who need to test registration flows or OTP delivery without polluting a real inbox; online shoppers who want to avoid marketing spam while still receiving order confirmations; business QA teams that require temp mail on their own domain for internal testing; and any privacy-conscious individual who needs to access gated content or trial accounts without exposing their primary email address.
What can you do with FreeCustom.Email?
- Online shoppers: Use a disposable email to receive purchase confirmations and tracking updates without subscribing to marketing lists.
- Developers: Integrate the API or CLI to automatically create inboxes, fetch messages, and extract OTP codes for bulk account automation or end-to-end testing.
- Business QA teams: Deploy temp mail on a custom domain to simulate real user sign-ups in staging environments, with support for large attachments (25MB on Pro) and permanent cloud storage (5GB).
- Privacy advocates: Generate a throwaway email for forums, free trials, or one-time verifications without linking to your personal address.
