I think this is a duplicate of #3032 and duplicates like #3191, #2661
Also see Pull request doing work in this area which have encountered problems:

• Feature: SMTP-templating of customBody and customHeader via liquidjs #3414
• Notification tests #760

If you agree, could you please close this Issue, as duplicates only create immortal zombies and are really hard to issue-manage?
If not, what makes this issue unique enough to require an additional issue? (Could this be integrated into the issue linked above?) ^^
