One account. A workspace per client.
Each workspace holds its own data. Reporting rolls up to the agency level; operations stay scoped to the client.

Every client is a separate workspace with its own credentials, domains, and suppression state.
The features that make agency work sustainable.
Custom roles per workspace
Client contacts see reporting only. Your team holds Admin or Operator. Audit logs track every change.
Full workspace isolation
Lists, domains, suppression, and sending credentials never leak between clients.
Shared template libraries
Build a pattern once, duplicate across clients. Update the source, push downstream.
Re-usable automations
Welcome flows, re-engagement, and drip sequences replicated to any workspace in seconds.
Per-workspace usage
Bill clients on your terms. We expose clear usage counters per workspace.
Audit trails per client
Who changed what, when. Critical when a client asks why their send looked different this month.
Reputation isolation
Separate sending domains and pools per client keep problems contained.
One contract, many clients
You own the Mailers.io contract. Clients don't need their own account.
How agencies actually use Mailers.io.
Scale the client roster without scaling the chaos.
Workspaces per client, roles per user, libraries across the business. One login, cleaner ops, happier clients.
