# What sends notifications

One capability in the whole suite sends notifications: Approval. Nothing else emails or messages anyone.

The second thing to know is that email and Slack are not alternatives. For the same event, both go out.

## Channels

![A Slack message from the Capable app reading approval request from Jack Graves for Get the most out of your team space, with Respond to request and View all requests buttons.](https://help.gocapable.com/images/3f89b7a2-bd12-4f09-b20a-65050af9c944.webp)

A Slack message names the requester, links to the page and carries buttons to respond without opening Confluence.

* Email, sent from a Capable address with Reply-To set to the person who requested the approval
* Slack direct messages to individuals, matched to their Confluence email address
* Slack channel broadcasts, configured per Confluence space by an administrator

---

## What triggers one

* Approval request from someone for a page
* Someone added you as an approver on a page
* A page has been updated and requires your approval
* An approver approved, rejected or commented on a request (optionally with a comment)
* A page has been approved
* A page has been rejected
* Your approval for a page has expired

ℹ️

**Watchers are set per space, up to 50 people**, and are notified on status changes. That is how people who are not approvers stay informed.

## A few things worth knowing

* If nothing in your site uses Approval, nobody will ever receive a Capable notification.
* Email comes from a Capable address with Reply-To set to whoever requested the approval, so replying reaches a person.
* Turning off email does not turn off Slack.
