SharePoint: Send email to unique addresses Created By with a count of times they appear

[cooper33]

I am trying to build a Flow that gives the user a summary of requests they submitted. I am storing items in a SharePoint list but since users often add many items, I don't want to send an email On Item Add because they'd get too many emails

Instead I want to send a summary email. At a high level, each day the flow would run and build a unique list of email address that have been added to the list in the last 24 hours. Each time the same email address appears in the query then a total would increment by one so that the email body to each user would say something like You added X items on [Today]

I can get the unique emails by building an array and then using Contains to only add unique users. I am assuming I shouldn't use an array data type if I want to store a number.

Can anyone explain how I can accomplish this?

I got this to work by building the same array with unique emails. After building the array, I loop through each and use the Get Items action to find items created in the past 24 hours where Created By email = current email in array

Created ge '@{formatDateTime(addDays(utcNow(),-1),'yyyy-MM-dd')}' and Author/EMail eq '@{items('Apply_to_each')}'

*Note the casing of EMail above is not a typo*

Then I used compose to get the length of get items and added it to the body of my email

Still feeling like this isn't the most efficient solution so if anyone has other ideas I'd love to hear
