# Subscribers

> Manage email and Slack audiences for release notifications.

DuckPost supports two subscriber channels:

* Email subscribers
* Slack channel subscribers

You manage both from [**Subscribers**](https://duckpost.app/subscribers).

## Email subscriptions

Email subscriptions use a confirmation flow:

1. A customer submits their email from the public page or widget flow.
2. DuckPost sends a confirmation email.
3. The subscriber becomes active after confirmation.

Customers can later unsubscribe through their unsubscribe link.

## Slack subscriptions

Slack subscriptions use Slack OAuth from the public page. A customer connects a Slack workspace and chooses a channel to receive release notifications.

## Managing subscribers

From the subscribers table, you can:

* Switch between **Email** and **Slack**
* Filter by enabled or disabled notifications
* Page through large subscriber lists
* Turn notifications on or off per subscriber

## What disabled means

An entry may appear disabled because:

* Your team turned notifications off for that subscriber
* Delivery became blocked
* The Slack channel subscription is no longer usable

## When notifications are sent

DuckPost sends notifications when a release becomes live and the release has subscriber notifications enabled.

That includes:

* Immediate publication
* Scheduled publication
* Auto-published release agent jobs
