I currently have a Power Automate that will send an email notification based on the emails in a SharePoint list field. I want to turn the flow off and add modifications to the flow and then turn it back on, but I noticed that each time I turn it on and off it will send out all the emails again. Is there a way to prevent the flow from sending all emails to preexisting items in my list?
What trigger you are using?
Can you confirm that you are using a "When an item is created" trigger? I ask because a Flow using that trigger should not fire again after yo turn it off/on. It should only run for new items created after the Flow is turned on again.
