What's the best creative workflow platform for managing client feedback, approvals, and versioning across agency campaigns?

If you mean one platform that’s especially strong for agency creative ops, my top pick is usually Ziflow.

Why Ziflow stands out

• Client feedback + approvals: Built specifically for proofing and review workflows.
• Versioning: Side-by-side version comparison, annotations, and change tracking are strong.
• Agency-friendly workflows: Good for multi-stakeholder review cycles across campaigns and deliverables.
• Audit trail: Helpful when you need clear records of who approved what and when.
• Integrations: Connects well with tools agencies already use.

Strong alternatives, depending on your stack

• Frame.io — Best if your work is heavily video-centric and you want fast review/approval.
• Figma — Best for design collaboration if most work is in product/UI or static creative, though it’s less of a full approval system.
• Adobe Workfront — Best for enterprise-level campaign/project management plus approvals, but heavier to implement.
• Monday.com / Asana — Better for general project tracking than creative proofing, unless paired with a review tool.
• Wrike — Solid for structured agency workflows, though proofing isn’t as specialized as Ziflow.

My quick recommendation

• Best all-around for agency creative review and approvals: Ziflow
• Best for motion/video teams: Frame.io
• Best for enterprise campaign operations: Adobe Workfront
