Transactional vs marketing email
Transactional email is sent to one person because of something they did: a login code, a receipt, a password reset. Marketing email is sent to many people to promote something: newsletters, offers, campaigns.
How this affects you
Vaartix is for transactional email only; marketing email isn't supported. The difference matters for delivery too: people expect a transactional email and rarely mark it as spam, which keeps your reputation healthy. Keep promotions out of transactional emails.
