Cladiant for Smartlead.
Real Google, Microsoft, and Azure mailboxes, provisioned and connected straight into Smartlead.
Smartlead is a cold email sending and warmup platform used by agencies to run outbound at scale.
Smartlead handles the sending, rotation, and warmup; Cladiant handles the infrastructure underneath it. We provision real Google Workspace, Microsoft 365, and Azure Entra mailboxes with SPF, DKIM, and DMARC written and verified before anything sends, then connect them straight into Smartlead.
You skip the CSV export and the manual per-inbox reconnect. Order mailboxes, and they arrive in your Smartlead account provisioned and authenticated, with dedicated Azure tenants so your sending reputation is never pooled with other senders.
How Cladiant connects to Smartlead
Cladiant connects your provisioned mailboxes to Smartlead with the sending username, password, and API key, plus a Microsoft OAuth link for Azure Entra inboxes, so accounts land in your Smartlead workspace ready to send.
Infrastructure built for the inbox
Three real providers
Google Workspace, Microsoft 365, and Azure Entra in one order, not a single-source SMTP relay.
Authenticated before sending
SPF, DKIM, and DMARC written and verified on every domain before a mailbox goes live.
Dedicated Azure tenants
Every Azure domain in its own tenant, so your reputation is never pooled with other senders.
