Hi @Loecha,
That will be a problem that when you upload 50 files will trigger Flow 50 times if you want to create an automatically Flow.
As a workaround, you can create a manually Flow to perform it. For example, after you upload these 50 files, perform the Flow with a manual trigger, initialize an array variable to store file name and file content, create Get files action, create a condition to find file that created in the past 5 minutes, if it is, gets file content and Append to the variable, after the loop, send email with attachment.
