In practice
Transactional messages confirm something a person did, such as a receipt. Promotional ones advertise. Newsletters inform on a schedule. Triggered messages respond to behaviour. Cold outreach goes to people who have not asked. Rules and expectations differ for each.
Verification and sending
Verification helps all of them. Cold outreach benefits most, since its addresses were collected rather than given.
