Bring your own VM from any provider. Run one command: we install, configure, and orchestrate the entire cold email stack. Your IPs. Your data. Your domains. We keep them healthy.
curl -fsSL inboxatscale.com/install | sh14-day trial · No credit card · Nothing irreversible happens without your approval
Every domain and IP you own, checked against 42 blacklists every five minutes. Anything that drifts is paused before it costs you a send.
Why InboxAtScale
Everything a cold email program needs to stay deliverable, running on hardware you control and pay for at cost.
You own the VMs, the domains, the email logs, the whole stack. If you churn, nothing is held hostage. Exports are one click.
A 200-mailbox setup runs about $100/mo in VMs plus $10 per mailbox. Equivalent SaaS tooling: $2–4k/mo. The math improves as you grow.
Rent any cheap VM. Run our install command. We take it from there: provisioning, DNS, rotation, monitoring, alerts.
How it works
Rent a VM from any provider. Run one command. We handle provisioning, DNS, monitoring and rotation from there.
Hetzner, Contabo, DigitalOcean, Scaleway, OVH. Wherever you like. Or let us provision one in a click.
