02

Deliverability automations

We monitor domain health and deliverability for you — so drift gets caught early, before it tanks your reply rate.

03

One order, one invoice

Bring, buy or mix domains across Google, Microsoft and Azure. No minimum contract. Cancel any time.

Questions

Things teams ask first.

01Do you handle provider accounts for me, or do I buy them myself?
We do. Cladiant claims and bills every Google Workspace, Microsoft 365, and Azure Entra tenant for you. You never touch a provider console. Workspace and Microsoft admin access is available on request; for Azure, our team handles all migration and reconnection end to end.
02Which senders does Cladiant integrate with?
Direct OAuth into Smartlead, Instantly, Email Bison, Salesforge, Outreach, Salesloft, PlusVibe, Saleshandy, Mailreach, Manyreach, and Supersend. Your mailboxes appear in your sequencer the moment provisioning completes — no CSV exports, no copy-paste.
03How is Azure Entra different from other Azure sellers?
You get a native Outlook experience — the inbox looks and behaves exactly like standard Outlook, which most Azure resellers can't offer. Dedicated tenant-level isolation means stronger inbox reputation, fewer throttling issues, and more consistent deliverability.
04How do I know DNS is actually set up right?
We verify propagation and auth on every domain before sending. MX resolves, SPF passes, DKIM signs, DMARC aligns. If any record isn't clean, we don't push the mailbox to your sequencer. You see the full diff in your dashboard.
05Can we bring our own domains?
Of course. Point your registrar at Cladiant and we handle DNS, authentication records, and mailbox provisioning automatically. Bring, buy, or mix in a single order.
06Do you handle warming and rotation?
No. Your sequencer already does that and does it well. Cladiant stops at handoff — we provision the mailboxes, authenticate the domains, and OAuth them into your sender.
07What makes Cladiant different from other providers?
Everything runs automated. Most providers lean on virtual assistants to hand-configure domains — that's where the misconfigurations and day-long delays come from. We provision a 100-mailbox batch in around six hours, and on Azure every domain sits in its own dedicated tenant.
08Is this a private or custom SMTP relay?
No. These are real Google Workspace, Microsoft 365, and Azure Entra accounts — the same enterprise-grade infrastructure Fortune 500 companies run on, not a grey-market SMTP server.
09Can we leave at any time?
Yes. No minimum contract. Cancel from your billing portal any time.
