Scenarios

#1 Build a screen to display OutSystems outgoing emails

Query the System Sent_Email entity for email metadata and the Email_Content entity for the email in MIME format.

Use the EmailUtils_ParseEmail action to retrieve the email HTML content and attachments.  Set StripAttachmentContent to True, so only attachment metadata is returned.  Set ConvertInlineImages to True so images will display in the HTML content.

Display the email HTML content using the IsolateHtmlBlock web block.

#2 Parse email content and store email content

Create entities to store email metadata and email content.

When email content is provided either via upload or a REST API, parse email content using the EmailUtils_ParseEmail action and store the email metadata and content in the entities.

For example usage a demo is available on the sample page.
