Hi Nick, I don't believe you'll be able to do this with a powerlist, as what you're really trying to do is report on absence of data, which a powerlist can't really handle.





Instead use a bionic query and accomplish this via three data tasks:





1 - fetch all users (and any other fields you'd want from those users to use in your outreach)





2 - fetch user name and SUM of post count (those two fields only), with a filter of 30 days (or whatever timeframe you want to search for). This will give you a count of the number of posts in that timeframe.





3 - merge those two data sets doing a left merge with fetch 1 on the left. This will give you a field added to your fetch 1 dataset that shows the count of posts in that timeperiod defined in step 2.





The reason this works is that you want to have a separate data set that shows all users regardless of post activity. Then you can filter to send this outreach only to users that have a post count of 0.

Isn't it possible to have the query look for Null values on the last login/post field and then just use an OR in the logic (e.g. Last Post < Subtract 30 days from Rule Date OR Last Post = Null)?
