@mattdjuk You can do a search for the string emailer.send( in src/ to see every invocation of the emailer.
From the first argument passed in, you can see which template it attempts to use, and the third argument shows the template data passed in.
e.g.
await emailer.send('notification', uid, {
path: notification.path,
notification_url: notification.path.startsWith('http') ? notification.path : nconf.get('url') + notification.path,
subject: utils.stripHTMLTags(notification.subject || '[[notifications:new_notification]]'),
intro: utils.stripHTMLTags(notification.bodyShort),
body: body,
notification: notification,
showUnsubscribe: true,
})
