  • This call spends one verification credit and blocks until Mailcheck answers; use mailcheck.check_emails for a whole list.

See Check Email Address run in a workflow.

In a technical demo we add the Mailcheck connection, drop the node on the canvas and let Workflow Health pre-flight it before the first real run.
