Agencies manage communication infrastructure for multiple clients simultaneously. Each client expects their own sending domain, their own branding, and their own analytics, but agencies need a single control plane to manage it all efficiently. Most agencies end up maintaining separate accounts across multiple vendors per client, which creates operational overhead that eats into margins.
Transactional's multi-tenant architecture is built for exactly this model. Each client gets an isolated organization workspace with its own domains, API keys, and team members. Agency staff can switch between client workspaces without logging in and out of separate accounts. Billing rolls up to the agency level while usage reporting breaks down by client.
The domains module lets you provision authenticated sending domains for new clients in minutes, not days. Combined with white-label email sending, your clients see their own brand on every communication while you retain full operational control.
Email and Domains are the core combination: send on behalf of clients from their own authenticated domains with isolated reputation tracking. Auth provides the multi-tenant workspace structure with granular roles for agency teams and client stakeholders. Calendar powers client-facing booking pages for calls and meetings. Forms handle client intake, creative briefs, and project requests. Support can be embedded in client-facing portals to offer white-label help desk functionality.
