Every client runs on its own domains, mailboxes, ramp curve and reputation record, and each one gets a report nobody on your team had to assemble by hand.

Average client inbox placement
Pooled reputation turns one client's bad week into everyone's throttle.
Shared domains, a shared warmup pool and hand-built reporting all fail at the same place: the third retainer.
Complaints don't stay in one account
On a pooled domain or IP, one client's complaint rate raises the deferrals and bounce codes every other client sees the same afternoon.
Reporting is assembled, not generated
Screenshots pasted into a deck every Friday is a job, and the hours grow in a straight line with the number of retainers you sign.
Churn leaves residue in the billing
With no boundary per client, a cancelled account's mailboxes, seats and invoice lines sit in the same pool as the accounts still paying.
A separate fleet per client, run from one login.
Domains, ramp curves, reputation history and invoices all stop at the workspace boundary.

Reputation stops at the boundary
Each client's domains and mailboxes carry their own sending history: a complaint spike in one workspace never moves another's placement.

Reports that write themselves
A branded weekly summary of placement, volume and domain health reaches each client without anyone opening a spreadsheet.
Seats scoped to one workspace
Account managers get edit rights where they work; clients get read-only on their own numbers and nothing beyond them.
Invoices split the way clients do
Bill retainers on their own cycle or invoice project work separately. The split is a property of the workspace, not a spreadsheet.
“Fourteen client fleets sit behind one login and none of them share a domain, a warmup pool or an invoice line. That was the whole decision.”
Six client fleets, no shared surface between them.
Switching workspaces changes the domains, the mailboxes, the ramp curve and the invoice. Your login is the only thing they have in common.

White-glove report, this week
Auto-sent FridaysBuilt for how retainers actually start and end
Offboarding without a cleanup week
Pause a workspace's sending or hand its domains over the day the contract closes.
Exports carry your name
PDF and CSV reporting goes out under your agency's brand, not ours.
Twenty mailboxes in one job
Name the pattern, set the count, and a new client's roster is provisioned in a single pass.
One seat pool, many workspaces
Account managers move between client fleets without a second login or a second licence.
Provisioning from your onboarding flow
Every workspace exposes the same REST endpoints, so client setup can run from your own tooling.
Warned before the overage lands
Usage alerts fire while there's still time to move a client up a tier, not after the invoice.
Fewer escalations, cleaner renewals.

The questions that come up in week one
No. Domains, mailboxes, warmup history, reputation records and billing are scoped to a single workspace and never join across them.
Yes. A workspace can sit on its own plan and cycle, or be invoiced manually, independent of every other client you run.
Pause the workspace and sending stops immediately, or transfer its domains and mailboxes into the client's own account.
Yes, scoped to their workspace. They see placement and volume for their own fleet and cannot reach settings or any other account.
Most agencies have a client's domains bought, records published and mailboxes created in under ten minutes.
Give every client a fleet of their own.
Start free, open your first client workspace today, and let the week-one report send itself.
