Hi @Anonymous
So let's figure this out.
I've simplified the Flow as you described into something like:
1. Schedule
2. Fetch data from Excel
3. Send
In the picture below, you can see the 2 options to send the email. You can use either. The difference is that Outlook will send in your name, and the other will send from a system account. There are other differences, but I think they are not important now.

The only question is, how do you want to send the information?
1. Attach the Excel file?
2. Fetch the information and send it?
Do you already have a draft Flow that we can work with?
Cheers
Manuel
