This is a duplicate of the From file to attachment:
If you want to attach an extra file to an outgoing email, then you can use the advanced, utilities workflow component, File to attachment to achieve that. The component has these parameters:
File path
This is the path to the file, that is to be attached.
Attachment name
The name of the attached file. So you decide for a name of the attachment independently of the original file name.
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.
