How can I get uploaded files sent to webforms to be attached to an email?
The steps to get uploaded files to be sent as attachments to be included in emails from Webforms go as follows:


Install SwiftMailer and Mail System Modules
In Mail System Module Configuration, add Webform Module and set Handler and Mailer to Swift Mailer
In Swift Mailer Configuration, Messages tab, set to HTML (may not be necessary, but it worked for me.
In Structure..Webforms..[your webform name]..Settings..Email/Handler..Edit..Advanced Tab set the check box for include files as attachments


The body of the email still has a broken image, but the files are attached.
I believe I can modify the body of the email to just include the fields that I want by expliciting naming each one, however, if you uncheck the fields that are "broken" in Included Email Values (hoping to continue to use [webform_submission:values] in the body template) the email does not show the broken connection but it also no longer includes the attached file(s)
