Create distribution list from a SharePoint list

Viccy  I made the second flow to remove people from the SharePoint list out for two main reasons. First, and easiest, is that SharePoint lists have a maximum of (I think) 500 items. The distro list I was working with is over 2000. The second reason is more of a cleaner programming logic. Person A signs up to the distro, they get added to the SharePoint list, no problem. Person B signs up to the distro, they get added to the distro; Person A shouldn't be added to the distro a second time, but they're on the SharePoint list so maybe(?). Now lets expand further and assume there's Person A, Person B, Person C, and Person D on the "add to distro" SharePoint list. Person C no longer wants to be in the distro list, MS Flow removes them from the distro. Note: Person C is still on the "add to distro" SharePoint list. Now, if, Person E wants to be added to the distro, MS flow might add Person C back into the distro.

All the explanation to say you probably don't need the delete functionality, but it's a best practice to have it. Hope that helps and explains things.
