Problem
Cold email outreach often suffers from low deliverability because new domains and mailboxes require weeks of warming and manual DNS configuration, leading to delayed campaigns and high risk of sender reputation damage.
Solution
Cheap Inboxes offers pre‑warmed Google Workspace and Microsoft 365 inboxes that are ready to send high‑volume emails from day one. The platform automates domain registration, DNS setup (including DKIM and DMARC), mailbox provisioning, and integration with any sequencing tool through a single developer‑first API call. Customers can purchase or import hundreds of domains, receive isolated workspaces for each domain, and connect the inboxes to their outbound platform automatically, eliminating manual setup and reducing warm‑up time. Real‑time webhook notifications inform users when domains and mailboxes are live, and 24/7 human support ensures issues are resolved quickly. This end‑to‑end infrastructure enables scalable, high‑deliverability outreach without the operational overhead of managing email infrastructure.
Target Audience
Primary customers are B2B sales and marketing teams, outbound agencies, and AI‑driven lead generation platforms that run large cold‑email campaigns and need automated, high‑deliverability inbox infrastructure.
