Best for agencies overall
Built for teams that juggle many inboxes for many clients. Comments, assignments and shared drafts keep account managers and support on the same thread without forwarding chaos. It is less a ticketing engine than a collaboration layer, which suits agency work well.
Multi-brand help centers and department-level controls let an agency run separate desks for each client under one login, cheaply. The denser interface is the price of that flexibility.
Spinning up a clean, separate mailbox and docs site per client is quick and tidy here. Reporting per inbox is clear for client updates. Additional inboxes carry a small monthly fee, so cost scales with your client count.
Handles several products or clients with shared agents and solid automation, at a friendlier price than Zendesk. The all-rounder choice when clients need ticketing rather than a pure shared inbox.
Multi-brand, deep routing and granular permissions make it the heavyweight option for a larger agency. The cost and setup effort only pay off once you are running real volume across several clients.
Turns Google Workspace into a shared help desk, so a small agency can manage client mail without leaving Gmail. The seat-count steps and Gmail-centric design limit it as you scale beyond a handful of clients.
