How do I tell a Zapier loop to send message only once to a user?

I have built  the following Zap

Description of Zap:

I have Google Sheet table. This table has columns.

One column is called “Due Date” another column is called “Returned”

Everyday at 8AM: IF Due Date is before today AND IF Returned = No, then I want the Zap to send me a single email notification.

I built the Zap and it works great, the issue is that I keep adding more rows everyday, and as I add rows I get more notifications. I want to limit the notification to 1 notification per row. So if I got one email today about Row#2, I do not want to get also tomorrow the notification about Row#2 again..

Here is how I built it:

1. Scheduled to work everyday at 8AM excluding weekends
2. Get Many Speadsheet Rows (Google Sheet)
3. Create a Loop from Line Item in Looping by Zapier
4. FIlter → Only continue if date is older then x
5. Send an email notification to myself (Gmail)

Now what happens is that everyday at 8AM I get the same emails from yesterday + the new emails from today.

I would like to know how can I limit the Zap to only send me 1 notification per Row. So I do not receive duplicate notifications every day for the same row I was already notified about in previous days.

Any suggestions?

Thanks in advance.
