Send Email

Send Email sends a message through an SMTP resource. Recipients, subject, body, and attachments are all mapped on the Input tab.

The sender address can come from three places. The input from is used if set, otherwise the From (override) configured here, otherwise the Default From on the SMTP resource.

The output reports recipients individually. Fail on Partial Reject decides whether a send where some recipients were rejected fails the activity or succeeds with those recipients listed in rejected.

The activity has four tabs: Configuration, Advanced, Input, and Output.

Name	Optional	Name of the component.
Description	Optional	Description of the component.
