Run multi-client outbound without juggling tabs.
Each client gets its own workspace, providers, domains, lists, and campaigns. Your team moves between them in one dashboard. Reports stay isolated. Clients stay yours.

An email platform built around the way agencies actually operate.
The typical agency setup looks like chaos inside: client A has Gmail + SES, client B has Mailgun and a dedicated SMTP relay, client C wants their own branded dashboard. Credentials scattered across password managers. Reports stitched together in spreadsheets.
Mailers.io is structured for that reality. Each client lives in its own workspace with isolated providers, domains, lists, and campaigns. Your operators move between workspaces in one session. Reporting and billing stay clean.
Onboard a client. Work their account. Report cleanly.
- Step 1
Spin up a workspace
New client = new workspace. Attach their providers, domains, and API keys. Nothing bleeds across workspaces.
- Step 2
Assign roles per client
Each operator gets the right role per workspace. Senior roles on strategy accounts; scoped roles on day-to-day ops.
- Step 3
Report per client
Per-workspace reports land in clean, brandable formats. Export or share without leaking data from other clients.
What an agency needs from an email platform.
Per-client workspaces
Every client is its own sealed environment. Zero risk of mixing their data with another client's.
Client-owned providers
Attach the client's own SES, Mailgun, SendGrid, or SMTP credentials. No resale margin for you or for us.
Cross-workspace operator view
Your operators switch between workspaces instantly. No logins per client, no creds passed around.
Role isolation per workspace
A user can be Owner on one workspace and Viewer on another. Access scales with engagement level.
Per-client quotas
Set sending caps per client based on their plan, their providers, or internal SLAs.
Routing per client
Each client's pool runs independently. A bad day on one client's SES never spills into another's.
Per-workspace reporting
Reports, dashboards, and event exports are scoped to the workspace you are inside.
Clean handover
When a client leaves, export their workspace data and hand them their credentials. No hostages.
- You run outbound email for multiple clients
- You want client-owned providers (no resale, no lock-in)
- You need per-workspace roles for your operators
- You want audit trails and clean handover when contracts end
- Workspaces are isolated by design; cross-workspace views apply to operators, not client data
- Billing is per-workspace or per-plan depending on how you configure it
- White-label UX is available on the Enterprise tier; baseline is shared domain
Questions answered clearly.
Run every client in one operational surface.
Per-client workspaces, per-client providers, per-client reports. Scale the agency without scaling the chaos.
