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
Sellvance is a GTM experimentation platform for B2B SaaS teams still searching for product-market fit. Validate an ICP, test an offer, or check demand for a feature by talking to real prospects.
Most cold email tools are built for volume. But zero replies can mean nobody wants your product, or that your emails never reached the inbox. Sellvance tells them apart. Every experiment gets a Signal Check: a delivery verdict (did the emails arrive?), an interest verdict (is the positive reply rate above your threshold?) and a harm verdict (unsubscribes). Until delivery is confirmed, Sellvance won't let you judge the reply rate.
Includes a 9.5M+ company database, enrichment with AI agents, AI-written messages, in-app domains and mailboxes, deliverability monitoring, and an MCP server to run campaigns from Claude.
Free Experiment Plan, no domain or mailbox needed. Paid plans from $199/month.
