| `.FallbackSubject` | string | Always | A default subject line. See Below. |
| `.Subject` | string | Only in body | The _subject_, once resolved. |
| `.Body` | string | Always | The message of the issue, pull request or comment, parsed from Markdown into HTML and sanitized. Do not confuse with the _mail body_ |
| `.Link` | string | Always | The address of the originating issue, pull request or comment. |
| `.Issue` | models.Issue | Always | The issue (or pull request) originating the notification. To get data specific to a pull request (e.g. `HasMerged`), `.Issue.PullRequest` can be used, but care should be taken as this field will be `nil` if the issue is *not* a pull request. |
| `.Comment` | models.Comment | If applicable | If the notification is from a comment added to an issue or pull request, this will contain the information about the comment. |
| `.IsPull` | bool | Always | `true` if the mail notification is associated with a pull request (i.e. `.Issue.PullRequest` is not `nil`). |
| `.Repo` | string | Always | Name of the repository, including owner name (e.g. `mike/stuff`) |
| `.User` | models.User | Always | Owner of the repository from which the event originated. To get the user name (e.g. `mike`),`.User.Name` can be used. |
| `.Doer` | models.User | Always | User that executed the action triggering the notification event. To get the user name (e.g. `rhonda`), `.Doer.Name` can be used. |
| `.IsMention` | bool | Always | `true` if this notification was only generated because the user was mentioned in the comment, while not being subscribed to the source. It will be `false` if the recipient was subscribed to the issue or repository. |
| `.SubjectPrefix` | string | Always | `Re: ` if the notification is about other than issue or pull request creation; otherwise an empty string. |
| `.ActionType` | string | Always | `"issue"` or `"pull"`. Will correspond to the actual _action type_ independently of which template was selected. |
| `.ActionName` | string | Always | It will be one of the action types described above (`new`, `comment`, etc.), and will correspond to the actual _action name_ independently of which template was selected. |
All names are case sensitive.
### The _subject_ part of the template
The template engine used for the mail _subject_ is golang's [`text/template`](https://golang.org/pkg/text/template/).
Please refer to the linked documentation for details about its syntax.
The _subject_ is built using the following steps:
* A template is selected according to the type of notification and to what templates are present.
* The template is parsed and resolved (e.g. `{{.Issue.Index}}` is converted to the number of the issue
or pull request).
* All space-like characters (e.g. `TAB`, `LF`, etc.) are converted to normal spaces.
* All leading, trailing and redundant spaces are removed.
* The string is truncated to its first 256 runes (characters).
If the end result is an empty string, **or** no subject template was available (i.e. the selected template
did not include a subject part), Gitea's **internal default** will be used.
The internal default (fallback) subject is the equivalent of:
<p>@{{.Doer.Name}} assigned you to the {{if eq .Issue.IsPull true}}pull request{{else}}issue{{end}} <a href="{{.Link}}">#{{.Issue.Index}}</a> in repository {{.Issue.Repo.FullName}}.</p>
<p>@{{.Doer.Name}} assigned you to the {{if .IsPull}}pull request{{else}}issue{{end}} <a href="{{.Link}}">#{{.Issue.Index}}</a> in repository {{.Repo}}.</p>
