The InfraMail alternative, built for deliverability.
Dedicated Azure Entra tenants and Google Workspace for real provider diversity, not shared Microsoft tenants on Outlook alone.
Inframail's flat, unlimited-inbox pricing is appealing for pure volume, but everything runs on shared Microsoft tenants and Outlook only. There is no Google Workspace, and the dedicated IP refers to the egress IP, not an isolated tenant.
Cladiant gives every Azure Entra domain its own dedicated tenant with a native Outlook experience, and adds Google Workspace for real provider diversity, handed to your sequencer over OAuth rather than raw SMTP credentials.

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.
