Hotmail OTP inbox API
Use arranged Hotmail.com inbox access for authorized incoming verification workflows. Retrieve the OTP email through API access after availability for your target service has been confirmed.
Hotmail within Microsoft's email ecosystem
Hotmail.com addresses now sit within Microsoft's Outlook ecosystem, while the domain remains relevant to many verification workflows. We confirm Hotmail.com availability separately rather than treating all Microsoft domains as identical.
The target service sends the email; our arranged workflow supports incoming retrieval. We do not generate the sender's OTP or control its acceptance rules.
Arrange a real verification test
Tell us which service will send the email and your expected volume. Test the exact Hotmail domain and sender before regular supply, including how your application distinguishes the latest message from older email.
If Hotmail is unavailable for the requested workflow, Outlook.com or Gmail.com alternatives can be discussed where supported.
Independent and authorized use
SMS Activation API is not affiliated with Microsoft. Inbox access must be used only for accounts, tests and business processes you are authorized to manage.
No inbox provider can guarantee that every third-party sender will deliver to every domain on every attempt.
Phone and email verification together
Businesses can also request virtual or physical SIM numbers for incoming SMS. Combining both channels in one supply discussion helps teams test which route fits each service.
