# Mailbox push delivery

> Understand the coming-soon push URL option shown when creating a mailbox.

The **Push URL** field in the mailbox creation flow is visible as a coming-soon option. It is disabled for now.

## What it will be for

Push delivery will POST inbound mailbox messages to a URL you control. It is intended for teams that want direct per-mailbox delivery without polling mailbox APIs.

## What to use now

* Use mailbox APIs to read folders, messages, threads, attachments, and changes.
* Use the Mailbox API event stream for live received-message notifications.
* Use webhooks to receive inbound event notifications.
* Use sender rules to reduce unwanted inbound mail before it reaches the mailbox.

## What happens next

There is no setup action or release date. You can create mailboxes normally while the field is disabled.
