Hi!
I am trying to set up a flow that will send a reminder email to all 'site owners' (see first image below) on a sharepoint list. However, before sending out the email I want the flow to check if there are duplicate email addresses in the column 'site owners'. If yes, then they must be skipped such that each site owner only receives one email.

This is what I have so far.

Does any one have any suggestions for how I can set up a duplicate check with a condition that checks for email addresses that appear more than once and eventually sends out out ONLY one email to each site owner.
