Send Email from Sharepoint with files(f.e. zip, pdf, docx)

Hello everybody im a student working for my company on a sharepointlist form which sends an automatically generated email with individual input values to our external Softwaredeveloping firm.

i completed 95%(or 90&) of my task and now i cant figure out a solution which saves time. I know that i might write some code lines but i need your help which way would be the most effective cause i started working with sharepoint on thursday.

Basically, the files should be attached to the email wich will be automatically send, after a new element was created by a user of the form. I can upload files directly into the listwindow while filling out the form, but it doesnt appear in the mail.

How can i link it?

I inserted everything into 1 emailworkflow. Which works pretty will but, without the files :(

WOuld be glad for a quick help!
