Email and notifications

When mail is sent

Mail is sent only when send_email is enabled in Configuration. Implemented via hook_mail() and entity insert/update hooks.

Event	Mail key	Recipients
Note created	insert	Collected from note owner, assignee, entity owner, revision author, parent thread participants (see below).
Note assigned (new or changed)	assign	Assignee.
Note resolved (published → unpublished)	resolve	Same as insert.
Note re-opened (unpublished → published)	re-open	Same as insert.

No mail is sent on note delete (resolve notification was already sent).

Recipients (insert / resolve / re-open)

_moderation_note_collect_recipients() in moderation_note.module gathers:

• Note owner
• Note assignee
• Notated entity owner (if EntityOwnerInterface)
• Revision author (if RevisionLogInterface)
• Parent note owner
• All children’s owners and assignees

Only active users with view access on the note are included; duplicates are removed.

Customization

• Disable: Set “Send email notifications” to off at /admin/config/moderation-note (see Configuration).
• Override body: Override template mail-moderation-note.html.twig in your theme.
• Mail plugin: Backend is moderation_note (class Drupal\moderation_note\Plugin\Mail\NoteMail). Subject and body are built in moderation_note_mail().
