Mail API

Use the mail API to customize mail content, format, and notification recipients.

Clients who use this API can make notification requests and extend construction of notification messages. The Mail API contains the Mail Client API, which makes notification requests, and the Mail Provider API, which implements notification requests.

The mail API also contains a function that is called Post Office that prevents workflow participants from receiving multiple email notifications that have similar content. Similar emails are stored, combined into a single email notification, and forwarded to a user.
