Where an email is sent to a person on an individual basis, usually as a result of an action they’ve taken (like making a purchase, or receiving a shipping update) is called Transactional Mailing.

Transactional emails are becoming essential to the way we interact with applications and services on the web. You know those emails from Facebook letting you know someone’s commented on a photo, or those receipt emails you get from Amazon? They’re transactional emails, with content that’s tailored specifically to you. Transactional email is a type of one-to-one email. It’s different from bulk email, which goes to many people with the same content.
