The current supported version is 4.54.00.

*Edge for Private Cloud v4.18.01*

Edge automatically sends emails in response to certain events. For each of these events, Edge
defines a default email template in /opt/apigee/edge-ui/email-templates. To
customize these emails, you can edit the default templates.

> [!NOTE]
> **Note:** These events are triggered when modifying users in the Edge management UI. If you use a script to add or modify a user, no email is sent.

The events where an email is sent, and the default template file for the generated email,
are:

- New user is added: user-added-new.html
- Existing user requests a password reset: password-reset.html
- A user is added to an organization: user-added-existing.html

> [!NOTE]
> **Note:** The next installation of Edge overwrites these files, so make sure to backup any customizations that you make.

The "From" field of the email can be set by using the conf_apigee_apigee.mgmt.mailfrom property in
/opt/apigee/customer/application/ui.properties (if
that file does not exist, create it). For example:

```
conf_apigee_apigee.mgmt.mailfrom="My Company <myCo@company.com>"
```

> [!NOTE]
> **Note:** Use the SMTPMAILFROM property in the installation configuration file to set the "From" field at install time. The SMTPMAILFROM property is required at install time. See [Edge Configuration File Reference](https://docs.apigee.com/private-cloud/v4.18.01/edge-configuration-file-reference) for more.

The email subjects are customizable by editing the following properties in /opt/apigee/customer/application/ui.properties
(if that file does not exist, create it):

- conf_apigee-base_apigee.emails.passwordreset.subject
- conf_apigee-base_apigee.emails.useraddedexisting.subject
- conf_apigee-base_apigee.emails.useraddednew.subject

Several email properties reference the {companyNameShort} placeholder, which
defaults to a value of "Apigee". You can set the value of the placeholder by using the
conf_apigee_apigee.branding.companynameshort
property in ui.properties. For
example:

```
conf_apigee_apigee.branding.companynameshort="My Company"
```

After setting any properties in /opt/apigee/customer/application/ui.properties,
you must restart the Edge UI:

```
> /opt/apigee/apigee-service/bin/apigee-service edge-ui restart
```
