Email infrastructure for outbound teams
Mailboxes built to scale. Deliverability built to last.
Provision Google and Microsoft mailboxes, configure authentication, monitor domain health, and connect your sending tools from one operational platform.
- No manual DNS setup
- Full administrative control
- API-ready
Start with one domain. Scale to thousands of mailboxes.
Works with the tools already in your outbound stack.
Operational workflow
From domain to sending-ready infrastructure
Replace manual setup, spreadsheets, shared credentials, and disconnected tools with one controlled provisioning workflow.
Connect domain
Add a domain you own and verify ownership through DNS.
Choose provider
Select Google Workspace or Microsoft 365 per domain.
Provision mailboxes
Create mailboxes in bulk with a naming pattern and workspace.
Configure authentication
Apply SPF, DKIM, and DMARC guidance automatically.
Warm reputation
Gradually ramp sending volume to build a healthy reputation.
Connect sending tools
Sync mailboxes to your sequencer and start sending.
Provisioning
Provision infrastructure without the operational work
Create mailboxes across Google Workspace and Microsoft 365 without coordinating multiple vendors, manually configuring every account, or tracking credentials in spreadsheets.
- Bulk mailbox provisioning
- Provider selection
- Domain assignment
- Automated account creation
- Central credential management
- Provisioning status tracking
- Failure recovery
- Full administrative access
| Domain | Provider | SPF | DKIM | DMARC | Warmup | Status |
|---|---|---|---|---|---|---|
| northwind.co | ok | ok | active | 14/15 | Healthy | |
| vertex labs.io | ok | ok | active | 20/20 | Healthy | |
| summit-outbound.com | Microsoft | ok | ok | missing | 5/15 | Needs attention |
| harbor-mail.net | fail | ok | pending | paused | At risk | |
| apex-reach.co | Microsoft | pending | pending | pending | 0/10 | Pending |
Recommended action: add a DMARC record before connecting additional mailboxes.
Monitoring
See infrastructure problems before campaign performance drops
Monitor authentication, blacklists, mailbox status, warmup progress, bounce behaviour, and domain health from one operational view.
- SPF, DKIM, and DMARC verification
- Blacklist and reputation checks
- Warmup progress per mailbox
- Bounce behaviour tracking
- Incident detection with remediation

What teams say after moving infrastructure here
“Before using the platform, our team managed mailbox provisioning, DNS records, and credentials in separate systems. Now the entire workflow is visible and controlled from one place.”
“We stopped rotating credentials in spreadsheets and stopped guessing which domains were healthy. Provisioning went from days to minutes across every client workspace.”
Only publish verified customer quotes and logos.
FAQ
Answers to the operational questions
Google Workspace and Microsoft 365, with mixed-provider support so you can assign the right provider per domain within a single workspace.
Yes. You retain full administrative access to every provisioned mailbox and workspace, including credentials, recovery settings, and account ownership.
You can connect an existing tenant or provision new ones through MailControl — both are supported, and you keep administrative control either way.
MailControl provides the exact DNS records and continuously verifies SPF, DKIM, and DMARC status, alerting you when a record is missing, misconfigured, or reverted.
Yes. Add any domain you own, verify ownership through DNS, and begin provisioning. Existing authenticated domains are imported with their current status intact.
Warmup controls are included on Growth and Platform plans, with per-mailbox progress tracking and configurable ramp schedules.
Native integrations include Smartlead, Instantly, HubSpot, and Clay, with API and webhook access for custom sending platforms.
Yes. Each client gets an isolated workspace with its own domains, mailboxes, credentials, billing, and role-based access — under one operational view for your team.
Yes. A documented REST API covers provisioning, domain management, health, and integrations, with webhook delivery for provisioning and incident events.
Pricing is based on the number of domains, mailbox volume, provider mix, and included features — use the infrastructure calculator above for an estimate, or contact sales for a configured quote.
Failed mailboxes are surfaced individually with the reason, a retry action, and an activity timeline, so a single failure never blocks the rest of the batch.
Yes. Existing domains, mailboxes, and credentials can be imported into a workspace with their current authentication and health status preserved.
Build outbound infrastructure without building an operations team.
Start with your first domain, provision mailboxes, authenticate your setup, and manage everything from one operational platform.
