How to check if a subscriber opens ANY email?

Your software

My PHP version is: 7.4.30
My Database type and version is: 10.3.35-MariaDB

Your problem
My problem is: I’m trying to set an “engagement check campaign” and I would like to be able to do basically the following:

  1. Lead subscribes, tag as active.
  2. Wait 7 days, check whether the person has opened ANY email. If not, tag as ‘disengaged’.
  3. If tagged as disengaged, remove from this campaign and add to a re-engagement campaign. If they engage there, tag as ‘active’ and re-add to original ‘engagement check campaign’.
  4. (original campaign) Wait 21 days, check whether the lead has opened ANY email. If not, tag as ‘Inactive’ and remove from segment.

This is ‘roughly’ it.

Mostly is already done… but I can’t find an option to check for ANY opened email… I always have to pick the ‘specific’ emails… does such an option even exist?
