InboxAPI

Send email through
your own mailbox.

InboxAPI connects your Outlook or Hotmail account with a secure Microsoft sign-in, then lets you send mail through your own mailbox no shared sending domain, no reputation to build, no separate inbox to manage.

Your mailbox, your identity

Mail sends from the real Outlook/Hotmail address you connect not a shared relay. Recipients see you, not a platform.

Secure Microsoft sign-in

Delegated OAuth via Microsoft Graph. InboxAPI never sees or stores your password.

Connect from any device

Generate a shareable link to finish sign-in on another browser or device no shared session needed.
