CheapInboxes
Volume-priced Google Workspace reseller targeting cold-email agencies with same-day delivery and a developer API, though independent reviews question whether accounts are truly pre-warmed and note limited company transparency given the domain was registered in August 2024.

Our take on CheapInboxes
CheapInboxes lives up to the name on price and adds an unusually capable developer API — 70+ endpoints with webhooks — plus same-day setup and no minimum order, which makes it attractive for teams that want to script provisioning cheaply.
The caveats are significant. The headline “pre-warmed / start sending right away” claim is directly contradicted by independent reviewers, who report no built-in warmup and the need to ramp manually. The homepage advertises Google and Microsoft inboxes, but only Google Workspace is actually documented in reviews — treat M365 as unconfirmed. The IPs are shared with no tenant ownership, and there's limited public information about the company — domain registered August 2024, private WHOIS, and few public reviews so far. Cheap and developer-friendly, but verify warming and Microsoft availability with a test account before trusting either.
What we like
- +Budget volume pricing with no minimum order
- +Developer-first REST API (70+ endpoints, webhooks)
- +Same-day automated setup
- +Single-mailbox entry
Watch out for
- −“Pre-warmed” claim contradicted by independent reviewers
- −Microsoft-inbox availability is undocumented (only Google verified)
- −Shared IPs, no tenant ownership
- −Newer brand (Aug 2024) with limited public reviews
Best for: Developers and agencies who want cheap, API-driven inbox provisioning and will handle warmup themselves.
