Total e-mails sent per day

[qwertzuiop]

I am very new to Power BI, but I have to present my work in a few days.

As you can see in the table, we have the collums:

- transportID

- created

- amountOfEmails

What I need to present is the total number of mails sent per day in a list and as a bar chart.

Can anyone help me?

Thank you very much.
