Campaign Collaborator is the system label for a magic-link guest invited to a single Campaign with no workspace membership. Signup-free for the guest, free for the workspace owner, never tier-gated as a paid seat. Available from Professional and above.
What the role can do
- Receive a magic-link invitation to one campaign.
- Open the campaign in a browser without creating an account.
- Comment on variations.
- Approve at the campaign’s sign-off stages if granted Approver permission.
- See exactly the assets shared with them on that campaign. Nothing from other brands. Nothing from other campaigns on the same brand. The brand-switcher chrome is not rendered.
UX naming: Client
In agency-client contexts, the UI labels Campaign Collaborator as “Client”. The underlying permission model is identical; the label changes to match the relationship the agency has with the person. For in-house teams sharing work with a stakeholder, the label can stay neutral or read as “Reviewer” depending on context. The technical role and the audit identity remain “Campaign Collaborator” throughout.
Why this is the viral channel
Every client review session on Brandflux exposes a client to Brandflux. The client doesn’t pay, doesn’t sign up, doesn’t see a paywall, and gets a fast, well-designed surface to react to work on. A subset of those clients run their own marketing function, recognize what they are seeing, and end up asking how to get one. The acquisition path runs entirely through the agency or the in-house team, not through Brandflux marketing.
The free posture on this role is deliberate. Charging guests would break the viral loop. The workspace owner pays for the seat that hosts the work; everyone the work is shared with rides free.
