Workflow preview
Provides a service that allows users to send emails.

This workflow, when deployed as a service deployment, allows you to delegate the ability to send emails via SMTP to other Hub users. The deployment must be created under a user scope. Once deployed, share this service deployment with the individuals or teams who need to send emails.

They can then trigger the email sending by calling this service deployment through a Call Workflow Service node (see link below).
When calling the service deployment, the following flow variables are expected:
- to (String): Hub User IDs or Email Addresses. If a Hub user ID is given, the users email is fetched, otherwise the given email address is taken.
- message_subject (String): The Subject of your message.
- message_body (String): The body of your message.
- message_format (String): "Text"|"Html". Choose whether the message should be interpreted as plain text or HTML.
