Bring your own VM from any provider. Run one curl — we install, configure, and orchestrate the entire cold email stack. Your IPs. Your data. Your domains. We just keep them healthy.
Shared P2P mesh — your inboxes warm each other using a controlled send/receive playbook. Positive contribution earns billing credits.
Why InboxAtScale
You own the VMs, the domains, the email logs, the whole stack. If you churn, nothing gets held hostage. Exports are one click.
A typical 200-mailbox setup runs ~$100/mo in VMs + our $10/mailbox. Equivalent SaaS tooling: $2–4k/mo. Math gets better the larger you get.
Rent any cheap VM. Run our curl. We take it from there — provisioning, DNS, warmup, rotation, monitoring, alerts.
How it works
Rent a VM from any provider. Run one curl. We handle the rest.
Hetzner, Contabo, DO, Scaleway, OVH — wherever. Or let us provision one in a click.
Our agent authenticates with your workspace key, inventories the box, reports home.
We auto-generate MX, SPF, DKIM, DMARC. Paste into your DNS and we verify within minutes.
Inboxes enter the warmup pool automatically. When reputation is strong, you start sending.
