InboxKit – Cold Email Infrastructure, Fully Automated
InboxKit is the most powerful platform for automating your cold email infrastructure at scale. Built as an official Google Cloud Partner and Microsoft Partner, InboxKit handles everything from domain purchasing to mailbox provisioning and DNS configuration—so you can focus on sending campaigns, not managing servers.
What InboxKit Does
InboxKit eliminates the technical complexity of cold email setup. Purchase domains directly within the platform, automatically provision Google Workspace or Microsoft 365 mailboxes, and let our system configure SPF, DKIM, and DMARC records without manual intervention. What typically takes hours of technical work happens in minutes.
Key Features
Automated Domain & Mailbox Provisioning – Buy domains, create mailboxes, and configure DNS records from a single dashboard. No switching between registrars, email providers, and DNS managers.
Official Provider Partnerships – As a Google Cloud Partner and Microsoft Partner, InboxKit provisions real workspace accounts with full infrastructure control—not pre-made mailboxes with questionable history.

Real-Time DNS Health Monitoring – Proactive alerts catch issues before they impact deliverability. Monitor blacklist status, DNS propagation, and inbox placement from one view.
Bulk Operations at Scale – Manage hundreds of domains and thousands of mailboxes with CSV uploads, bulk actions, and
