The Mailscale alternative, built for deliverability.
Real Google, Microsoft, and Azure mailboxes with dedicated tenants, not shared-pool SMTP inboxes, handed off over OAuth.
Mailscale is built for speed and low cost on its own shared-pool SMTP, great for bulk provisioning, but the deliverability ceiling and sender reputation are tied to a pool you share with other senders.
Cladiant provisions real Google Workspace, Microsoft 365, and Azure Entra accounts, with each Azure domain in its own dedicated tenant, a higher deliverability ceiling than shared SMTP, handed off to your sequencer over OAuth.

What you actually get with Cladiant
Three real providers, one order
Diversify across Google Workspace, Microsoft 365, and Azure Entra in a single checkout - real enterprise accounts, not a grey-market SMTP relay.
Automated, not hand-built
No virtual assistants configuring domains by hand. DNS, SPF, DKIM, and DMARC are written and verified on every domain before a mailbox sends.
Dedicated tenants on Azure
Every Azure domain sits in its own tenant. Your reputation is never tied to someone else's sending in a shared pool.
Straight into your sequencer
We OAuth your mailboxes into Smartlead, Instantly, Salesforge, and more the moment provisioning completes. No exports, no copy-paste.
24/7 human support
Reach the team any time over email, Slack, or WhatsApp - real people who know your setup, not a ticket queue that replies next week.
Automations built for top-notch deliverability
We provide n8n automations that keep you ahead of deliverability. The moment a domain or mailbox gets affected, it is pulled from your campaigns and sending and moved straight to warmup - so one bad inbox never drags down the rest of your outreach.
