The Maildoso alternative, built for deliverability.
Google Workspace, Microsoft 365, and Azure Entra under one order, with dedicated tenants instead of a shared SMTP tier.
Maildoso competes hard on price, and its cheapest inboxes run on its own shared SMTP infrastructure, the tier where reputation is most easily shared between senders. There is no Microsoft 365 or Azure path at all.
Cladiant adds real Microsoft 365 mailboxes and dedicated Azure Entra tenants alongside Google Workspace, so you can diversify providers and keep each Azure domain isolated in its own tenant.

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.
