Part 2 - 30/60/90 Day Email Engagement (List Based)

This automation works in conjunction with Part 1 - 30/60/90 Day Email Engagement (List Based)

This automation will tag users based on when they last opened or clicked on an email. This is useful for engagement tagging for campaign sends, or to fire a sunset inactive subscriber automation when they go dormant.

Part 2 acts as the countdown trigger, that adds and removes users from Part 1 based on a recent email read or click.

Active Campaign has a similar automation for engagement tagging. However, this is different as it is a classical definition of email engagement which to me is more useful for campaign engagements segmentation.
