Gerrit uses Closure Templates (Soy) for the bulk of the standard mails it sends out. There are builtin default templates which are used if they are not overridden. These defaults are also provided as examples so that administrators may copy them and easily modify them to tweak their contents.

Compatibility Note: previously, Velocity Template Language (VTL) was used as the template language for Gerrit emails. VTL has now been deprecated in favor of Soy, but Velocity templates that modify text emails remain supported for now.

Template Locations and Extensions:

The default example templates reside under: '$site_path'/etc/mail and are terminated with the double extension .soy.example. Modifying these example files will have no effect on the behavior of Gerrit. However, copying an example template to an equivalently named file without the .example extension and modifying it will allow an administrator to customize the template.

Supported Mail Templates:

Each mail that Gerrit sends out is controlled by at least one template. These are listed below. Change emails are influenced by two additional templates, one to set the subject line, and one to set the footer which gets appended to all the change emails (see ChangeSubject.soy and ChangeFooter.soy below.)

Many types of Gerrit email message support HTML in addition to plain-text. Where both are supported, templates to control the HTML part have …​Html appended in their file names. For example, for "Abandoned" emails, the Abandoned.soy template determines the text part of the message, whereas AbandonedHtml.soy determines the HTML part.

Abandoned.soy and AbandonedHtml.soy

The "Abandoned" templates will determine the contents of the email related to a change being abandoned. It is a ChangeEmail: see ChangeSubject.soy and ChangeFooter.

AddKey.soy and AddKeyHtml.soy

AddKey templates will determine the contents of the email related to SSH and GPG keys being added to a user account. This notification is not sent when the key is administratively added to another user account.

ChangeFooter.soy and ChangeFooterHtml.soy

The ChangeFooter templates will determine the contents of the footer that will be appended to emails related to changes (all `ChangeEmail`s).

ChangeSubject.soy

The ChangeSubject.soy template will determine the contents of the email subject line for ALL emails related to changes.

Comment.soy

The Comment.soy template will determine the contents of the email related to a user submitting comments on changes. It is a ChangeEmail: see ChangeSubject.soy, ChangeFooter and CommentFooter.
