# Single send

*Marketing*. A non-recurring email message that communicates non-automated, non-sequential content.

You can deliver this message to a list or segment of your contacts, in the moment or scheduled for future delivery. Unlike an [automated email][] series such as a [drip campaign][], this message doesn't belong to a series of related messages designed to work in sequence, a [campaign][].

Single Sends work for both [transactional email][] and [promotional message][] use cases:

* promotional offers
* engagement campaigns
* newsletters
* announcements
* legal notices
* policy updates
