Re: Flow to Send One Email instead of Multiple Emails
Hi @theBrianL
Thank you for your further explanation. Sorry for the misunderstanding.
If the email address is static with grab 'send email' outside of loop. We will receive one email. But it's weird from your end. Thus, I recommend you can change flow from the beginning.

Flow details:

formatDateTime(utcNow(),'yyyy-MM-dd')
formatDateTime(addDays(utcNow(),1),'yyyy-MM-dd')
Filter query is used to reduce returned items based on modified date. It will make a query between today and today +1 with the ge and lt. It functions as condition.

The delay action is used to spare some time for flow to write data into excel. For how long we need to configure, it depends on the actual data from ‘get items’. I set up a 5 minutes delay here. If you have plenty of data needs to copy, you can set up it longer.
Once tested, only items modified today are filtered and wrote to excel. Meanwhile I only receive one email as you required.

Hope it helps.
Thanks
Anna
