# 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`](https://github.com/netdata/netdata/blob/master/docs/netdata-agent/configuration/README.md#edit-a-configuration-file-using-edit-config) script from the
Netdata [config directory](https://github.com/netdata/netdata/blob/master/docs/netdata-agent/configuration/README.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
Config Options
| Name | Description | Default | Required |
|:----|:-----------|:-------|:--------:|
| EMAIL_SENDER | You can change `EMAIL_SENDER` to the email address sending the notifications. | netdata | no |
| SEND_EMAIL | Set `SEND_EMAIL` to YES | YES | yes |
| DEFAULT_RECIPIENT_EMAIL | Set `DEFAULT_RECIPIENT_EMAIL` to the email address you want the email to be sent by default. You can define multiple email addresses like this: `alarms@example.com` `systems@example.com`. | root | yes |
##### DEFAULT_RECIPIENT_EMAIL
All roles will default to this variable if left unconfigured.
The `DEFAULT_RECIPIENT_CUSTOM` can be edited in the following entries at the bottom of the same file:
```text
role_recipients_email[sysadmin]="systems@example.com"
role_recipients_email[domainadmin]="domains@example.com"
role_recipients_email[dba]="databases@example.com systems@example.com"
role_recipients_email[webmaster]="marketing@example.com development@example.com"
role_recipients_email[proxyadmin]="proxy-admin@example.com"
role_recipients_email[sitemgr]="sites@example.com"
```
#### Examples
##### Basic Configuration
```yaml
#------------------------------------------------------------------------------
# email global notification options
EMAIL_SENDER="example@domain.com"
SEND_EMAIL="YES"
DEFAULT_RECIPIENT_EMAIL="recipient@example.com"
```
## Troubleshooting
### Test Notification
You can run the following command by hand, to test alerts configuration:
```bash
# become user netdata
sudo su -s /bin/bash netdata
# enable debugging info on the console
export NETDATA_ALARM_NOTIFY_DEBUG=1
# send test alarms to sysadmin
/usr/libexec/netdata/plugins.d/alarm-notify.sh test
# send test alarms to any role
/usr/libexec/netdata/plugins.d/alarm-notify.sh test "ROLE"
```
Note that this will test _all_ alert mechanisms for the selected role.
