If you want to attach an extra file to an outgoing email, then you can use the advanced, utilities workflow component, From variable to attachment to achieve that. The component has these parameters:
Variable name
The name of the variable from which the data is to be copied from.
Decode base64
If the data in the variable is stored as an encoded base64 data stream, then you can enable this to convert the base64 data stream into a binary data stream.
Attachment name
The name of the attachment in the workflow, that is to receive the data from the variable.
If you see an attachment name when you receive the email like this:
Then you are probably using an invalid characters in the attachment name. There is no standard as to which characters, that are allowed so you need to test for invalid characters and e.g. replace characters not found in the lists: a-z, A-Z and 0-9. On one mail server the dash (minus) character caused such an attachment name.
