Hi Mustafa,

You can create a table for the records you are sending as mail through the action flow by using the data push api

https://docs.celonis.com/en/create-and-push-csv-to-data-integration.html

Another approach is if you are using views i.e. the user comes into the view selects the records and performs an action (send email in this case). In this case you can use Augmented Attributes. Update the value after every email sent. I would send an email and update my augmented attribute to "Completed". This helps me track all cases that have be sent over an email. 

Hello Abhishek,

That is the link I was following.

I am not sure how to handle Augmented Attributes yet. I will look into that as well.

Thanks
