The PremiumInboxes alternative, built for deliverability.
The same official Google and Microsoft accounts, provisioned by automation with dedicated Azure tenants and monitoring included, not upsold.
PremiumInboxes leans on manual, human-verified setup of official Google and Microsoft accounts. Solid work, but hand-configured, and their real-time monitoring is gated to premium tiers.
Cladiant automates the same SPF, DKIM, and DMARC setup end to end, adds dedicated Azure Entra tenants, and pushes mailboxes into your sequencer over OAuth the moment provisioning completes, with monitoring included rather than upsold.

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.

Cladiant vs PremiumInboxes, answered

Yes, if you want automation and included monitoring. PremiumInboxes hand-verifies official Google and Microsoft accounts and gates real-time monitoring to premium tiers; Cladiant automates the same setup and includes monitoring.
What is the difference between Cladiant and PremiumInboxes?

Tenant isolation is not publicly documented, and there is no Azure option. Cladiant gives every Azure Entra domain its own dedicated tenant.
