If a partner has a workflow that generates emails and runs out of email credits, Zift123 will pause the workflow. The partner is notified via email that the workflow has been automatically paused because of the lack of email credits.

Partner Administrators can request more email credits by navigating to Settings > Mailing Credits or wait until additional credits are refreshed at the beginning of each month. Keep in mind the workflow does not resume until the partner has additional email credits and starts the workflow again.
