In datacenter you can modify the email-batch velocity templates. But there does not appear to be a cloud equivalent. We are aware of the configuration for modifying the email templates for JSM customer notifications (Space Settings → Notifications → Customer notifications) but that only customizes the emails back to the customer. It does not customize emails sent internally. This is a problem because the content may be sensitive so our notifications are not allowed to include the content. We are also aware that we could disable all notifications and then use Automations to send custom notifications (via the Send customized email action), but this would mean notifications dont get batched and these notifications would get applied to our action quotas (not to mention the tedium to disable all current notifications and manually create all the actions).
Are we missing something here? It feels like we must just not be finding the documentation to do the same thing we could do with DataCenter, but it is possible that its just not possible…
