What are the numbers at the top, bottom, and in the top right corner of each element in my workflow?

These numbers illustrate how many contacts have entered a particular element of your workflow, how many contacts are in this element right now and how many contacts have already left it.

The number at the top of the element is the overall number of contacts who have entered this element.

The number in the top right corner illustrates how many contacts are currently in the element. You may find it especially useful for elements with a “When to assume the condition wasn’t met” setting available in Properties and for a Wait element.

The number at the bottom of the element illustrates how many contacts have gone past this particular element of the workflow.

After you publish your workflow (that is make it running), you can observe these numbers to see the dynamics of the entire process. You can also use these numbers to identify steps in the workflow that block it from running.
