Flow sending duplicate emails with every run

[lynnosler]

I have built a flow for a SharePoint list.  The initial trigger is "when an item is modified or created".  It is a simple flow with one control and a switch.  The control checks to see if a certain field is true or false.  If it is true, it sends an email then moves on to the switch which is based on a Status.  The problem is, if this item is one that gets an email sent, it is sending an email every time this flow is triggered.  I only want it to send an email ONCE on the initial run.  How can I accomplish this?

Hi @lynnosler -

Could you share an image with the configuration of your Flow? It will help in determining what you are attempting to build so people can better assist.

Hi @lynnosler ,

It seems that we don't quite understand what you mean, maybe you can consider using When an item is created as the trigger.

In addition, the method you can consider is to create a Yes/No column in the list. After the email is sent, use the Update item action to update the Yes/No field value to Yes.

Then set the trigger conditions, and trigger only when the value of the Yes/No field is false, so that the requirement of sending the email only once can be achieved.

Hope that makes sense.
