Four stages, one pipeline

A pipeline, not a checklist.

Stage 01

Claim tenants

Batch-create Google Workspace, Microsoft 365, and Azure Entra tenants. Cladiant carries billing across providers; you run the campaigns.

Stage 02

Register domains

$13.50 .com domains (budget TLDs $9.00), no hyphens, no junk TLDs - or bring your own from any registrar. DNS zones configured and propagation verified before we proceed.

Stage 03

Write auth

MX, SPF, DKIM, DMARC written on every domain. Mailboxes, aliases, and forwarding generated across providers. SMTP and IMAP tested end to end.

Stage 04

Push to your sequencer

We OAuth into Smartlead, Instantly, Emailbison, Salesforge, Outreach, Salesloft, and more, and upload your mailboxes for you. No CSV exports. Your sequencer runs warming and rotation from there.

Questions

Things agencies ask first.

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 work end to end.
Direct OAuth into Smartlead, Instantly, Emailbison, 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. API and webhooks are coming soon.
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. Smartlead, Instantly, Emailbison, Salesforge, or anything in our integration list takes it from there.
We verify propagation and auth on every domain before sending. MX resolves, SPF passes, DKIM signs, DMARC aligns. If any record is not clean, we do not push the mailbox to your sequencer. You see the full diff in your dashboard.
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. Domains bought through us are $13.50 for a .com, or $9.00 for budget TLDs (.net / .co / .org / .info / .biz), billed on your first invoice.
Five steps. Basics, domains, accounts, delivery, review. Live price in the right rail. One invoice, monthly. Cladiant provisions, OAuths into your sequencer, and flips the order to Active. Unlimited team members can join your workspace at no extra cost.
Coming soon. Today every order is placed through the dashboard and pushed to your sequencer over OAuth. Public API and webhook support is on the near-term roadmap.
Yes. No minimum contract. Cancel from your billing portal any time. Workspace and Microsoft admin access is available on request; Azure migration and reconnection are handled end to end by our team if you switch off.
Everything runs automated. Most providers lean on virtual assistants to hand-configure domains, which is where the misconfigurations and 24-hour-plus delays come from. Cladiant provisions a 100-mailbox batch in around six hours. And on Azure, every domain sits in its own dedicated tenant - you are never bundled into a shared pool where someone else's sending can drag down your reputation.
No. These are real Google Workspace, Microsoft 365, and Azure Entra accounts - the same enterprise-grade infrastructure that Fortune 500 companies run on, not a grey-market SMTP server. Running across all three providers lets you diversify properly instead of leaning on a single source that takes a day to deliver.
You get a native Outlook experience - the inbox looks and behaves exactly like standard Outlook, which most Azure resellers cannot offer. Worth asking any other provider whether their solution is truly native. Beyond the UI, dedicated tenant-level isolation means stronger inbox reputation in warmup, fewer throttling issues, and more consistent deliverability.
Capacity scales with your order. Google Workspace and Microsoft 365 run one to five mailboxes per domain; Azure Entra runs 25 or 50 per domain - you choose. You decide how to split names across them. Daily volume and warmup ramp are controlled by your sequencer - we hand off clean, authenticated mailboxes and your sender sets the pace from there.
We have tested with lead-gen agencies sending several hundred thousand emails a month. Cladiant mailboxes hold up against direct-buy and reseller inboxes, and consistently let teams scale volume without sacrificing performance. Follow best practices and you can expect at least the same results you get today, with far more headroom to grow.
Placement depends on your content, sending reputation, and warmup strategy - no provider can honestly promise 100% primary placement. We optimize everything at the infrastructure layer and let you spread sending across Google, Microsoft, and Azure for the best possible shot. Azure Entra is especially strong for Outlook placement.
Reach out and we will audit your setup against the best practices in our onboarding guide. Reply rates come down to far more than the infrastructure - but with Cladiant you can be certain the infra side is best in class, so you can focus on offer, copy, and targeting.
Swap it for a fresh one. If a domain gets flagged, you replace it from the dashboard - buy a clean .com through us for $13.50 (or a budget TLD for $9.00), or bring one you already own. DNS and authentication are reconfigured automatically on the replacement.
Yes. Plenty of teams run Cladiant in parallel with other infrastructure to diversify their sending and spread risk. Use it as your primary source or as one more provider in the mix - your call.
No free trial, but every plan is month-to-month with no long-term contract, so you can test the platform without locking in. Cancel any time from the web app - no support ticket required.
