Flow / Unit types / Sink / Email Sink
Email Sink
Description
This unit is a Sink unit type.
The Email Sink unit sends input events through email. If a provider configuration is not set, the unit will use the Devo's Amazon SES service to send the email.
The events enter via the in port and the event details and custom messages are sent to the configured destinations.
In the case of an error, these events are enriched with two additional fields, error and exception, and the event is output through the error port.

Example
In this example, we want to send an HTTP request to the randomuser.me API, which retrieves random user information. We need to send this information by email with a specific delay. To do it, we add a Tick unit to fire the request every time we need it. Then, we link it to the input port of the Delayer unit and join its output port to an Http call unit, configured with the API information. Finally, we add an Email Sink unit to send it to the required recipients.
In the Email Sink unit properties, you must specify the required subject and message of the emails and the list of addresses to which you want to notify.
