About

InboxKit is the leading cold email infrastructure platform that automates domain and mailbox provisioning at scale. We help cold email agencies, sales teams, and outbound consultancies set up Google Workspace and Microsoft 365 mailboxes in minutes, not hours. Key features include automated DNS configuration, one-click export to 15+ sequencers (Instantly, SmartLead, Lemlist, Reply.io, etc.), real-time deliverability monitoring, and bulk mailbox management. As an official Google Cloud Partner and Microsoft Partner, we provide enterprise-grade infrastructure without the manual setup overhead.

About

Maildoso provides outbound mailboxes built for cold email, combining SMTP and Google Workspace infrastructure, fast setup, strong deliverability, and automated technical configuration. It helps teams diversify their sending strategy with reputable mailboxes built specifically for cold outreach, so campaigns are not dependent on one sender type, domain, or provider. Users can register domains directly in the dashboard or connect their own, enter mailbox names, and have SPF, DKIM, and DMARC auto-configured so mailboxes are ready to export and use with outreach platforms in minutes. Maildoso supports SMTP mailboxes, Google Workspace mailboxes, and combined setups, giving teams flexibility based on their sending strategy and target audience. It connects with popular sequencers and outreach tools such as Instantly, Smartlead, Saleshandy, and others, making it easier to move newly created mailboxes into active campaigns.
