Email for your applications
Send email through an API or SMTP. Receive email on your domains and work with messages through the API and webhooks.
Sending
Connect your application.
Submit transactional and permission-based email through the Outbu API or authenticated SMTP, and follow delivery events through webhooks and the dashboard.
Send from domains you control and verify in Outbu, with domain authentication and separate project credentials.
Receiving
Build with incoming email.
Receive messages for your configured domains and mailboxes, then retrieve their content through the API or connect inbound events to your application with webhooks.
Manage sending and receiving from the same account, with access scoped to your projects.
Sending safety
Build reputation with care.
Outbu applies domain verification, sending limits and warmup controls. Bounce and complaint events feed suppression and sending-safety controls.
Use Outbu for messages recipients have requested or expect from your application. Senders are responsible for recipient permission and clear unsubscribe options for subscription email.
