# Email
Send notifications via Email using Netdata's Agent alert notification feature, which supports dozens of endpoints, user roles, and more.
## Setup
### Prerequisites
####
- A working sendmail command is required for email alerts to work. Almost all MTAs provide a sendmail interface. Netdata sends all emails as user netdata, so make sure your sendmail works for local users.
- Access to the terminal where Netdata Agent is running
### Configuration
#### File
The configuration file name for this integration is `health_alarm_notify.conf`.
You can edit the configuration file using the `edit-config` script from the
Netdata [config directory](https://github.com/netdata/netdata/blob/master/docs/configure/nodes.md#the-netdata-config-directory).
```bash
cd /etc/netdata 2>/dev/null || cd /opt/netdata/etc/netdata
sudo ./edit-config health_alarm_notify.conf
```
#### Options
The following options can be defined for this notification
