Quick answers to common questions.

InboxKit is your complete cold email infrastructure in one place. We deliver Google, Microsoft, and Azure mailboxes with zero setup fees—fully automated, fastest in the market, and integrated with 16+ sequencers. Manage all your mailboxes from a single dashboard with automated billing, InfraGuard protection, Email Analytics, Bounce Monitoring, and Inbox Placement Tests. Everything you need to land in primary, without the complexity.

InboxKit provides official Google Workspace Business accounts with verified US IP addresses, achieving industry-leading 95% inbox placement rates. Unlike other providers, you get complete admin control over each domain, built-in 2FA security, app passwords for seamless integration with any email platform, and our proprietary warmup system that builds sender reputation automatically. Our infrastructure is built specifically for email outreach with advanced features like domain rotation, engagement tracking, and real-time deliverability monitoring.

Getting started takes less than 10 minutes with our completely automated setup process. Simply connect your domain, and our system instantly configures all DNS records (SPF, DKIM, DMARC), creates your Google Workspace account with US IP allocation, enables 2FA security, generates app passwords for your outreach tools, and begins the automated warmup sequence. Most users see dramatic deliverability improvements within the first 24 hours, with full optimization achieved after our 14-day warmup protocol.

We have 16+ integrations live in the platform directly, or you can build your own integration smoothly. InboxKit integrates seamlessly with major email platforms including Instantly, Smartlead, Apollo, Reply, Lemlist, Plusvibe, and many more. Our universal app password system works with any SMTP-compatible platform, ensuring 100% compatibility. We also provide a comprehensive REST API, webhook notifications for real-time events, and SDKs for popular programming languages. Our technical team offers free integration support to help you connect any custom tools or workflows to your InboxKit infrastructure.

We provide 24/7 expert technical support across all plans via live chat, email, and phone. Our support team consists of email deliverability specialists who can resolve complex issues quickly. Agency and Enterprise plans include priority support with sub-4-hour response times, dedicated success managers for strategic guidance, and access to our technical implementation team for custom configurations. We also offer comprehensive onboarding, regular health checks, and proactive monitoring to prevent issues before they impact your campaigns.

For Google, Microsoft, and Azure mailboxes, we complete orders in 30 to 120 minutes automatically. This includes setting up the admin panel, configuring DKIM, adding profile pictures, making accounts public, and connecting with your email sending platform.

Absolutely! Our white-glove migration service handles the complete transfer of your existing email infrastructure, campaigns, and data to InboxKit with zero downtime. The process includes: comprehensive audit of your current setup, automated data export and import, DNS record migration and optimization, campaign continuity planning, and parallel testing to ensure everything works perfectly. Most migrations complete within 24-48 hours, and our migration specialists provide step-by-step guidance throughout the process. We also offer rollback capabilities and 30 days of post-migration support to ensure a smooth transition.

Make your cold emails count

No setup rituals. No DNS sorcery. Just emails that send, land, and look damn good doing it. Get started now. Because why wait?
