Resend adds Inbound feature for webhooks-based email receiving and processing

Resend has launched Inbound, extending its platform beyond sending emails to now support receiving and processing incoming messages. Inbound operates through webhooks, delivering structured JSON payloads to a specified endpoint each time an email arrives. This approach gives developers immediate programmatic access to parsed content, message metadata, and stored attachments through the Resend platform.

Each inbound email is automatically parsed, with the system saving both attachments and event data before sending it to the configured webhook. Developers can use default inbound domains supplied by Resend or set up custom domains for addresses tailored to their brands. If a webhook is not ready, Resend retains all inbound emails, preventing data loss and allowing users to access messages once their endpoint is available.

While developers benefit from programmatic attachment handling via a dedicated API, users can also view and filter received emails on the Resend dashboard. The dashboard displays content in HTML or plain text, as well as attachment previews. Typical use cases include enabling in-app replies, supporting ticket systems, or automating document processing workflows.
