Re-enrollment loops
Contacts being enrolled in the same workflow over and over because re-enrollment is on and the exit criteria are missing or wrong. Creates thousands of unnecessary actions.
Missing or broken branches
If/then branches that never get updated when the business changes. A "is a customer" branch that still routes to the 2021 onboarding sequence nobody uses anymore.
Wrong trigger timing
Workflows that fire immediately when they should wait, or wait 5 days when the window for a useful response has already closed.
No exit criteria
Contacts who've already converted still receiving nurture emails because there's no exit criteria checking for deal stage or lifecycle stage changes.
Conflicting workflows
Two workflows enrolling the same contacts and fighting each other — updating the same property to different values, creating duplicate tasks, sending overlapping emails.
Abandoned workflows
Workflows that were turned off but never deleted. Workflows that were paused "temporarily" in 2022 and never reviewed. Technical debt that makes auditing your portal harder every month.
