I’ve been running my own mailserver for a while.

Having no code in your workflow has been a best practice for some organizations for years and as a low-code platform, it’s a nobrainer. However, there are requirements that always required code in the past, one of those Asynchronous server events.
With the release of K2 4.6.11 a new wizard has been added to the k2 blackpearl software. It’s the For Each wizard, which might surprise you. How can a workflow engine like K2 not have a For Each option? It’s quite simple once you understand how the K2 workflow engine works.
