How Agencies Run Cold Email for Many Clients Safely
Running outreach for multiple clients? Keep mailboxes, lists, reputations, and reports separate. How Infiara’s isolated workspaces make agency cold email safer.
Key takeaway
Agencies run cold email for many clients safely by isolating each client: separate mailboxes on the client’s own domain, separate lead lists and suppressions, and separate reporting and billing. In Infiara each client is a workspace, and nothing crosses workspace lines.
Agency outreach fails in a specific way: one client’s bad list damages another client’s results, or a suppressed contact gets emailed again under a different client. Both come from mixing data and infrastructure.
The isolation checklist
- Each client sends from mailboxes on their own domain.
- Lead lists, templates, and suppressions are per client.
- Inbox replies and tasks are per client.
- Analytics and invoices are per client.
- Agency staff switch clients with one login; client users only see their own workspace.
Roles that match how agencies work
Invite people as owner, admin, or member per workspace. Members do not get Senders or Billing unless an owner grants that role, so a contractor can run campaigns without touching mailbox credentials.
Onboarding a new client in a day
- Create the client workspace and invite the client’s owner.
- Connect the client’s mailboxes on Senders and send a test from each.
- Verify SPF, DKIM, and DMARC for the client’s domain on Domains.
- Import the client’s lead list; duplicates and suppressed contacts are skipped.
- Draft the first campaign, review it with the client, and launch.
Reporting clients actually read
Clients care about conversations, not opens. Lead the weekly report with positive replies and meetings, then show volume, replies, and bounces per mailbox from the workspace analytics. Because every number comes from that client’s workspace only, there is no risk of showing one client another client’s data.
Frequently asked questions
Can a client log in to see their own results?
Yes. Invite client users to their workspace with the role you choose. They cannot see other clients.
Do clients share sending infrastructure?
No. Each workspace sends from its own connected mailboxes.
Connect Gmail, Google Workspace, Microsoft 365, or SMTP, import a list, and let Infiara run personalize → send → follow up → stop on reply → AI reply triage.
